SHINGLED SOLAR CELL ARRANGEMENT, AND METHOD FOR

SEPARATING A SOLAR CELL INTO TWO OR MORE SOLAR CELL PIECES

FIELD [0001] Embodiments of the present disclosure relate to an apparatus for use in the manufacture of a solar cell arrangement, a system for the manufacture of at least one shingled solar cell arrangement, and a method for separating a solar cell into two or more solar cell pieces. Embodiments of the present disclosure particularly relate to an apparatus, system and method for the manufacture of shingled solar cell arrangements.

BACKGROUND

[0002] Solar cells are photovoltaic devices that convert sunlight directly into electrical power. An efficiency of the solar cells can be affected by an active area on a front surface of the solar cell that is exposed to light for converting sunlight into electrical power. The active area can be reduced due to the presence of electrical contacts, such as fingers and/or busbars, on the front surface of the solar cells. The presence of the electrical contacts on the front surface of the solar cells can thus reduce a module power of a solar cell module consisting of the solar cells.

[0003] Shingled solar cell arrangements can increase an output power of a solar cell module. The increase in the output power can be affected by a quality of a manufacturing process, such as a quality of the elements used to assemble the shingled solar cell arrangement. Further, a proper assembling of the shingled solar cell arrangement can be cumbersome, and a throughput and/or yield can be low.

[0004] In view of the above, new apparatuses for use in the manufacture of a solar cell arrangement, systems for the manufacture of at least one shingled solar cell arrangement, and methods for separating a solar cell into two or more solar cell pieces, that overcome at least some of the problems in the art are beneficial. The present disclosure particularly aims to improve a manufacturing process of solar cell arrangements.

DETAILED DESCRIPTION OF EMBODIMENTS

[0011] Reference will now be made in detail to the various embodiments of the disclosure, one or more examples of which are illustrated in the figures. Within the following description of the drawings, the same reference numbers refer to same components. Generally, only the differences with respect to individual embodiments are described. Each example is provided by way of explanation of the disclosure and is not meant as a limitation of the disclosure. Further, features illustrated or described as part of one embodiment can be used on or in conjunction with other embodiments to yield yet a further embodiment. It is intended that the description includes such modifications and variations.

[0012] Shingled solar cell arrangements can increase an output power of a solar cell module. The increase in the output power can be affected by a quality of a manufacturing process, such as a quality of the elements used to assemble the shingled solar cell arrangement. Further, a proper assembling of the shingled solar cell arrangement can be cumbersome, and a throughput and/or yield can be low.

[0013] The present disclosure mechanically holds and separates a solar cell from the same side. A well-defined, smooth and accurate breaking edge can be achieved. A quality of the solar cell pieces used to assemble a solar cell arrangement, such as a shingled solar cell arrangement, can be improved and an output power can be increased. The separation process can provide for an increased yield and/or an increased throughput of a system for manufacturing the solar cell arrangement.

[0014] FIGs. 1A and B show schematic side views of an apparatus 100 for use in the manufacture of a solar cell arrangement, such as a shingled solar cell arrangement, according to embodiments described herein.

[0015] The apparatus 100 includes a separation device 110 configured to mechanically contact a first surface 12 of a solar cell 10 to divide the solar cell 10 into two or more solar cell pieces, and a holding device 120 configured for mechanically contacting the first surface 12 of the solar cell 10 to hold the solar cell 10 at a support arrangement at least while the solar cell 10 is divided into the two or more solar cell pieces, such as a first solar cell piece 16 and a second solar cell piece 18.

[0016] The separation device 110 can be configured to mechanically contact a first portion of the first surface 12 of the solar cell 10. The holding device 120 can be configured to mechanically contact a second portion of the first surface 12 of the solar cell 10. The first portion and the second portion can be spaced apart from each other. In some implementations, the spacing between the first portion and the second portion can be less than a width of the two or more solar cell pieces. In further implementations, the spacing between the first portion and the second portion can be greater than a width of the two or more solar cell pieces. The width of a solar cell piece can be defined perpendicular to a breaking line or breaking edge defining a respective solar cell piece.

[0017] According to some embodiments, the solar cell 10 has the first surface 12 and a second surface 14 opposite the first surface 12. The first surface 12 can be a frontside or front surface of the solar cell 10 and the second surface 14 can be a backside or back surface of the solar cell 10. In some implementations, the solar cell 10 can have one or more conductive patterns, such as fingers and/or busbars, provided thereon. In particular, the term "solar cell" can refer to a finished or nearly finished solar cell instead of, for example, an unprocessed semiconductor substrate. The fingers and/or busbars can be deposited on the first surface 12, for example, using a printing technique such as screen printing. Optionally, the solar cell 10 can have one or more contacts, such as back contacts, on the second surface 14.

[0018] According to some embodiments, which can be combined with other embodiments described herein, the support arrangement includes a first support 130 configured for supporting the solar cell 10 and a second support 140 configured for supporting at least one solar cell piece of the two or more solar cell pieces obtained from the solar cell 10. The first support 130 can be configured to support the second surface 14 of the solar cell 10. As illustrated in FIG. 1A, the first support 130 can support the solar cell 10 such that the solar cell 10 protrudes over an edge of the first support 130 by a predetermined distance, particularly during the separation process. The predetermined distance can be greater than the width of the solar cell piece that is to be separated from the solar cell 10. As an example, the separation device 110 can be configured to contact the solar cell 10 at, or away from, an edge or edge portion of the first support 130 to break the solar cell piece off the solar cell 10, as is exemplarily shown in FIG. IB. [0019] The solar cell piece that has been separated from the solar cell 10, such as the second solar cell piece 18, can be collected by the second support 140. The remaining solar cell piece of the solar cell (also referred to as '^remaining solar cell"), such as the first solar cell piece 16, can remain on the first support 130. In some implementations, one or more further solar cell pieces can be separated from the solar cell piece of the remaining solar cell on the first support 130, such as from the first solar cell piece 16. The solar cell 10 can be divided into any suitable number of solar cell pieces, such as two, three, four, five, six, or even more solar cell pieces.

[0020] According to some embodiments, the second support 140 is offset by an amount D with respect to the first support 130 in an offset direction, which can be essentially perpendicular to the first surface 12 of the solar cell 10. The offset direction can be an essentially vertical direction (e.g., the z-direction). The solar cell piece, such as the second solar cell piece 18, can fall onto the second support 140 when the solar cell piece is separated from the solar cell 10 or remaining solar cell.

[0021] The separation device 110 is configured to separate the solar cell 10 into two or more solar cell pieces. In particular, the separation device 110 can create smaller cells (solar cell pieces or solar cell elements) starting from the (big) solar cell. The two or more solar cell pieces have essentially the same dimensions, such as lengths and/or widths.

[0022] According to some embodiments, which can be combined with other embodiments described herein, the separation device 110 includes a moveable body 112 and a contact element 114 connected to the moveable body 112. The contact element 114 can be configured to contact the first surface 12 of the solar cell 10 to divide the solar cell 10 into the two or more solar cell pieces. The contact element 114 can also be referred to as "cleaving device". The contact element 114 and the moveable body 112 can be provided as separate entities, or can be integrally formed from a single piece of material, such as a plastic material.

[0023] In some implementations, the contact element 114 can be a blade or an element with a sharp tip configured to contact the solar cell 10 for cleaving and dividing the solar cell 10. According to some embodiments, the contact element 114 can be made of a plastic material. However, the present disclosure is not limited thereto and the contact element 114 can be made of other materials, such as ceramics and/or metal.

[0024] In some implementations, the moveable body 112 can be configured to move the contact element 114 towards the solar cell 10, for example, in a quick motion, in order to provide a sharp dividing line at the solar cell 10. As an example, the apparatus 100 can include an actuator, such as a linear actuator, configured for moving the moveable body 112 in a moving direction, which can be essentially perpendicular to the first surface 12 of the solar cell 10. The moving direction can be an essentially vertical direction, such as the z-direction. As an example, the separation device 110 can push the moveable body 112 having the contact element 114 attached thereto against the solar cell 10 in order to cleave the solar cell 10. According to some embodiments, the moveable body 112 can be movable substantially vertically towards and away from the solar cell 10, e.g., in an up- and down- movement. The up- and down-movement can be repeated in predetermined intervals to divide the solar cell 10 into the two or more solar cell pieces.

[0025] The apparatus 100 includes the holding device 120 configured for mechanically contacting the first surface 12 of the solar cell 10 to hold the solar cell 10 at the support arrangement, and particularly at the first support 130. In particular, the holding device 120 can press against the first surface 12 such that the second surface 14 is pressed against the first support 130. By fixing the solar cell 10 to the support arrangement, e.g., by holding the solar cell 10 down at and against the support arrangement, a reliable separation process can be provided.

[0026] In some implementations, the holding device 120 can be moveable in a direction essentially perpendicular to the first surface 12 of the solar cell 10, e.g., in an essentially vertical direction, such as the z-direction. The holding device 120 can include an actuator, such as a linear actuator, to move the holding device towards and away from the solar cell 10. By moving the holding device 120, the holding device 120 can either contact the solar cell 10 for holding the solar cell, or cannot contact the solar cell 10 such that the solar cell 10 can move below the holding device 120. Another example of a holding device using rollers is illustrated in FIGs. 3A and B.

[0027] In some embodiments, the holding device 120 can be configured to essentially prevent a movement of the solar cell 10 in a plane essentially parallel to the first surface 12 of the solar cell 10, e.g., the x-y-plane, which can be an essentially horizontal plane. As an example, the holding device 120 can provide a frictional force against the first surface 12 such that the solar cell 10 cannot move in the plane essentially parallel to the first surface 12. An accurate alignment of the solar cell during the separation process can be achieved. [0028] According to some embodiments, which can be combined with other embodiments described herein, the apparatus 100, and particularly the separation device 110, further includes at least one solar cell perforation device configured for providing one or more predetermined breaking points or predetermined breaking lines on the first surface 12 of the solar cell 10. As an example, the at least one solar cell perforation device includes, or is, a laser. As an example, the at least one solar cell perforation device can be configured to perforate the solar cell 10 to define the breaking points or lines for the two or more solar pieces before the solar cell 10 is separated into the two or more solar cell pieces by the separation device 110. [0029] The at least one solar cell perforation device can be configured to generate one or more predetermined breaking points or lines on the solar cell 10 such that the solar cell 10 can be easily broken into the two or more solar cell pieces. As an example, the at least one solar cell perforation device can be configured to provide a plurality of predetermined breaking points along a substantially straight line on the solar cell that defines a separation line between two adjacent solar cell pieces. In another example, the at least one solar cell perforation device can be configured to provide a continuous predetermined breaking line on the solar cell 10 that defines the separation line between two adjacent solar cell pieces. The perforation of the solar cell 10 before the cleaving action can provide for a straight and sharp edge at the solar cell piece that is broken off the solar cell 10. In particular, for hypercell creation, the solar cell 10 can be previously lasered in order to cleave the solar cell 10 into the smaller cells in a controlled manner.

[0030] The solar cell arrangements of the present disclosure can be shingled solar cells or shingled solar cell arrangements, which can also be referred to as "hypercells" or "supercells". The solar cell arrangements can be used in solar cell modules. The solar cell arrangements can be made of a plurality of partially overlapping pieces (also referred to as "solar cell pieces" or "solar cell elements"). Adjacent solar cell pieces are electrically connected to each other in the overlapping region. The solar cell pieces are connected in series such that current generated by the individual solar cell pieces flows along the series of solar cell pieces to be collected, for example, at an end portion of the solar cell arrangement. The overlapping configuration can provide high-efficiency solar cell arrangements. In particular, the solar cell arrangements allow to increase a module power by increasing a used or active area. Typically, the overlapping configuration can increase the module power by, for example, 20 to 40 Watts. The used or active area can correspond to an area that is irradiated by solar light and that participates in the generation of power. As an example, the used or active area can correspond to an area of the solar cells that is not covered by, for example, conductive line patterns, such as fingers and/or busbars.

[0031] In some cases, a solar cell piece of a solar cell arrangement can have a high resistance and/or low efficiency when compared to the other solar cell pieces of the solar cell arrangement. An overall performance including, but not limited to, the module power of the solar cell arrangement and/or solar cell module can be affected or determined to a considerable extent by the solar cell piece having the high resistance and/or low efficiency. This low-quality solar cell piece particularly acts as a "bottleneck" within the solar cell arrangement.

[0032] The present disclosure mechanically holds and separates the solar cell from the same side. A well-defined, smooth and accurate breaking edge can be achieved. A quality of the solar cell pieces used to assemble a solar cell arrangement, such as a shingled solar cell arrangement, can be improved. A module power can be increased, particularly because "bottlenecks" due to low-quality solar cell pieces can be avoided.

[0033] FIG. 2 shows a schematic top view of an apparatus 200 for use in the manufacture of a solar cell arrangement, such as a shingled solar cell arrangement, according to embodiments described herein.

[0034] According to some embodiments, which can be combined with other embodiments described herein, the first support is a first transportation device 230 configured for transportation of the solar cell to the separation device. The second support can be a second transportation device 240 configured for transportation of the two or more solar cell pieces, such as the first solar cell piece 16 and the second solar cell piece 18, away from the separation device. The first transportation device 230 can be configured for transportation of the solar cell 10 in a first transport direction. Likewise, the second transportation device 240 can be configured for transportation of the two or more solar cell pieces in a second transport direction. The first transport direction and the second transport direction can be essentially parallel. In some embodiments, the first transport direction and/or the second transport direction can be essentially horizontal directions.

[0035] In some implementations, the first transportation device 230 and/or the second transportation device 240 can be belt conveyors configured for conveying the solar cell 10 and/or solar cell pieces, as is shown in the top view of FIG. 2. The first transportation device 230 and/or the second transportation device 240 can each have two or more belts spaced apart from each other. In particular, a gap can be provided between the two or more belts.

[0036] In some embodiments, an inspection system can be provided, for example, below the first transportation device 230 and/or the second transportation device 240 to determine, for example, a position of the solar cell 10 and/or the two or more solar cell pieces on the respective transportation device. The gap between the two or more belts can ensure that the inspection system, and particularly a camera thereof, can see the solar cell 10 or solar cell pieces located on the first transportation device 230 and/or the second transportation device 240. Further, a contact area between the solar cell 10 or solar cell pieces and the respective transportation device can be minimized to avoid damaging the solar cell 10 or solar cell pieces.

[0037] According to some embodiments, which can be combined with other embodiments described herein, the apparatus 200 further includes an alignment device 250 configured for aligning the solar cell 10 before the solar cell 10 is divided into the two or more solar cell pieces. The alignment device 250 can be a centering device, such as a mechanical centering device, configured to center or align the solar cell 10 which is to be divided into the two or more solar cell pieces. As an example, the centering device can be provided at the separation device 110 to center or align the solar cell 10 with respect to the separation device 110. In particular, the solar cell 10 can be centered or aligned before the solar cell 10 is inputted into the separation device 110.

[0038] In some implementations, the alignment device 250, the holding device 120, and the separation device can be sequentially arranged along the first transport direction. As an example, the alignment device 250, the holding device 120 and the separation device can be provided at the first support, which can be the first transportation device 230. [0039] The solar cell 10 is separated into two or more solar cell pieces. FIG. 2 exemplarily illustrates two solar cell pieces, namely the first solar cell piece 16 and the second solar cell piece 18, and further illustrates a fresh solar cell on the first transportation device 230, from which no solar cell pieces have been separated yet. It is to be understood that the apparatus 200 can be configured for separating each solar cell 10 into a suitable number of solar cell pieces, such as two, three, four, five, six, or even more solar cell pieces.

[0040] The first transportation device 230 can transport the solar cell 10 to the separation device such that the solar cell 10 can be divided into the two or more solar cell pieces. In some implementations, the first transportation device 230 is configured for positioning the solar cell 10 with respect to the separation device, and particularly the contact element 114, such that the two or more solar cell pieces can be broken off the solar cell 10 in a controlled and well-defined manner. As an example, the first transportation device 230 can be configured to position the solar cell 10 such that a breaking line or breaking edge is positioned at, or near, the contact element 114. In particular, the solar cell 10 can be positioned such that the contact element 114 contacts the first surface 12 of the solar cell 10 adjacent to breaking line to break off the respective solar cell piece.

[0041] In some implementations, a movement of the first transportation device 230 in the first transport direction and a movement of the separation device, such as a movement of the movable body and the contact element 114, can be synchronized. As an example, the movable body and the contact element 114 can repeatedly move upwards and downwards, wherein the first transportation device 230 can position the solar cell 10 underneath the contact element 114 e.g. during the upward movement of the movable body and the contact element 114. The first transportation device 230 can be configured to move intermittently such that the solar cell 10 or the remaining solar cell is stationary below the contact element 114 when the contact element 114 contacts the first surface to break off a solar cell piece.

[0042] According to some embodiments, the second transportation device 240 can move continuously in the second transport direction. In other words, a movement of the second transportation device 240 and a movement of the first transportation device 230 and/or the separation device may not be synchronized. However, the present disclosure is not limited thereto and a movement of the second transportation device 240 and a movement of the first transportation device 230 and/or the separation device may be synchronized.

[0043] FIGs. 3A and B show schematic views of a holding device 320 according to embodiments described herein. FIG. 3A shows a front view of the holding device 320 in the first transport direction. FIG. 3B shows a side view of the holding device 320 perpendicular to the first transport direction, which can be the x-direction.

[0044] According to some embodiments, which can be combined with other embodiments described herein, the holding device 320 includes one or more rotatable holding units 322. In some implementations, the one or more rotatable holding units 322 can be selected from the group consisting of rollers, rods, cylinders, and any combination thereof.

[0045] The one or more rotatable holding units 322 can be configured to be rotatable around a rotational axis A. The rotational axis A can be essentially parallel to the first surface 12 of the solar cell 10. Additionally or alternatively, the rotational axis A can be essentially perpendicular to the first transport direction. The rotational axis A can be an essentially horizontal rotational axis. The term "essentially perpendicular" relates to an essentially perpendicular orientation e.g. of the rotational axis A and the first transport direction, wherein a deviation of a few degrees, e.g. up to 10° or even up to 15°, from an exact perpendicular orientation is still considered as "essentially perpendicular". Likewise, the term "essentially parallel" relates to an essentially parallel orientation e.g. of the rotational axis A and the first surface 12, wherein a deviation of a few degrees, e.g. up to 10° or even up to 15°, from an exact parallel orientation is still considered as "essentially parallel".

[0046] According to some embodiments, the holding device 320 includes one or more bearings connected to the one or more rotatable holding units 322. As an example, a rotatable holding unit of the one or more rotatable holding units 322 can be supported by one or more respective bearings. In particular, the rotatable holding unit can be held by two bearings, which may be provided at, for example, opposite ends or end portions of the rotatable holding unit. The one or more bearings can be configured such that the one or more rotatable holding units 322 can freely rotate, e.g., without being actively rotated by an actuator, such as a motor. However, the present disclosure is not limited thereto and the holding device 320 can include an actuator configured to rotate the one or more rotatable holding units 322 around the rotational axis A.

[0047] In some implementations, the holding device 320 includes one or more surface contact elements 324 attached to the one or more rotatable holding units 322. The one or more surface contact elements 324 can be fixed to the one or more rotatable holding units 322 so as to rotate together with the one or more rotatable holding units 322. The one or more surface contact elements 324 can be configured for mechanically contacting the first surface 12 of the solar cell 10 to hold the solar cell 10 at the support arrangement, e.g., the first support 340. The one or more surface contact elements 324 can clamp the solar cell 10 between the one or more surface contact elements 324 and the first support 340.

[0048] The one or more surface contact elements 324 rotate e.g. while the solar cell 10 is transported along the first transport direction such that the one or more surface contact elements 324 roll over the first surface. In other words, the one or more surface contact elements 324 do not glide over the first surface of the solar cell. Damage to the solar cell, such as scratches and/or a damaging of the fingers and busbars, can be avoided.

[0049] According to some embodiments, the one or more rotatable holding units 322 include one or more recesses 426 (see FIG. 4) extending in a circumferential direction of the one or more rotatable holding units 322. The one or more recesses can be configured to accommodate the one or more surface contact elements 324. In particular, a recess of the one or more recesses can accommodate a respective surface contact element of the one or more surface contact elements 324. The one or more recesses can prevent a movement of the one or more surface contact elements 324 in a direction along the rotational axis A. In some embodiments, each recess of the one or more recesses can accommodate a respective surface contact element. In further embodiments, only some recesses of the one or more recesses can accommodate a surface contact element. A number of surface contact elements provided at the one or more rotatable holding units 322 can be selected based on at least one of a kind of solar cell and a configuration of the support arrangement, such as the first transportation device 230. [0050] In some implementations, the one or more surface contact elements 324 can include, or be made of, an elastic material configured for mechanically contacting the first surface of the solar cell. The elastic material can be selected from the group consisting of an elastomer, rubber, thermoplastic, and any combination thereof. As an example, the one or more surface contact elements 324 can be O-rings.

[0051] According to some embodiments, which can be combined with other embodiments described herein, the holding device 320 is configured to prevent a movement of the solar cell 10 in a plane essentially parallel to the first surface 12 of the solar cell 10. The plane can be an essentially horizontal plane. As an example, the one or more surface contact elements 324 can prevent a movement of the solar cell 10 using frictional forces between the one or more surface contact elements 324 and the first surface 12 of the solar cell 10. A precision of the separation process can be improved.

[0052] FIG. 4 shows a perspective view of an apparatus 400 for use in the manufacture of a solar cell arrangement, such as a shingled solar cell arrangement, according to further embodiments described herein.

[0053] The apparatus 400 can be configured according to the embodiments described herein. FIG. 4 exemplarily illustrates the separation device 410 having an actuator 411 and a blade 412 attached to the actuator 411 and configured for mechanically contacting the solar cell 10 to divide the solar cell 10. The apparatus 400 further includes the holding device 420 having a roller 422 with recesses 426, wherein some of the recesses 426 accommodate O-rings 424. The apparatus 400 includes the second support, which can be a belt conveyor having a first belt 442 and a second belt 444 spaced apart from each other in a direction perpendicular to the second transport direction.

[0054] FIG. 5 shows a flow chart of a method 500 for separating a solar cell into two or more solar cell pieces according to embodiments described herein. The method 500 can be implemented using the apparatuses and systems according to the present disclosure.

[0055] The method 500 includes, in block 510, mechanically contacting a first portion of a first surface of the solar cell to hold the solar cell at a support arrangement, and, in block 520, mechanically contacting a second portion of the first surface to divide the solar cell into the two or more solar cell pieces.

[0056] The first portion and the second portion can be spaced apart from each other. In some implementations, the spacing between the first portion and the second portion can be less than a width of the two or more solar cell pieces. In further implementations, the spacing between the first portion and the second portion can be greater than a width of the two or more solar cell pieces. The width of a solar cell piece can be defined along the first transport direction provided by the support arrangement.

[0057] In some implementations, the method further includes intermittently moving the solar cell in the first transport direction. The solar cell can move intermittently such that the solar cell (or the remaining solar cell) is stationary below the contact element when the contact element contacts the first surface to break off a solar cell piece.

[0058] According to embodiments described herein, the method for separating a solar cell into two or more solar cell pieces can be conducted using computer programs, software, computer software products and the interrelated controllers, which can have a CPU, a memory, a user interface, and input and output devices being in communication with the corresponding components of the apparatus.

[0059] FIG. 6 shows a schematic view of a system 600 for the manufacture of at least one shingled solar cell arrangement, such as two or more shingled solar cell arrangements, according to embodiments described herein. The system 600 can be part of a larger production line, as is for example described with respect to FIGs. 10A and B.

[0060] The system 600 includes the apparatus 610 for use in the manufacture of a solar cell arrangement according to the embodiments described herein, and at least one positioning device 620 configured for positioning the two or more solar cell pieces on a support device 630 to assemble the at least one shingled solar cell arrangement.

[0061] The apparatus 610 includes the separation device configured for separating a solar cell 10, such as a first solar cell, into two or more first solar cell pieces, and the at least one positioning device 620 configured for positioning at least one first solar cell piece 17 of the two or more first solar cell pieces on the support device 630 for forming a first solar cell arrangement of the at least two solar cell arrangements and for positioning at least one further or other first solar cell piece 19 of the two or more first solar cell pieces on the support device 630 for forming a second solar cell arrangement of the at least two solar cell arrangements. The solar cell pieces, such as the two or more first solar cell pieces, can also be referred to as "solar cell elements" or "small(er) cells".

[0062] The apparatus 610 divides the solar cell 10 into a plurality of solar cell pieces, wherein at least two solar cell pieces of said solar cell 10 can be allocated to two different solar cell arrangements. As an example, the solar cell arrangements can be shingled solar cells, wherein solar cell pieces of one or more solar cells including the first solar cell can be allocated to the respective solar cell arrangement based on characteristics and/or quality of the individual solar cells and/or solar cell pieces. An efficiency of the solar cell arrangement can be improved, particularly since "bottlenecks" in the solar cell arrangement due to low-quality and/or high-resistance pieces can be avoided.

[0063] According to some embodiments, which can be combined with other embodiments described herein, the at least one positioning device 620 is configured to arrange a plurality of solar cell pieces, such as a plurality of first solar cell arrangement pieces, including the at least one first solar cell piece 17 on the support device 630 with adjacent solar cell pieces partly overlapping with each other to form the first solar cell arrangement. The at least one positioning device 620 can be further configured to arrange a plurality of other solar cell pieces, such as a plurality of second solar cell arrangement pieces, including the at least one other first solar cell piece 19 on the support device 630 with adjacent solar cell pieces partly overlapping with each other to form the second solar cell arrangement. Accordingly, the hypercell can be formed by smaller cells assembled as shingles. The overlapping configuration of a solar cell arrangement is further explained with respect to FIG. 7.

[0064] According to some embodiments, the apparatus 610 is configured for separating a second solar cell into two or more second solar cell pieces. The first solar cell and the second solar cell can be inputted into and/or processed by the apparatus 610 sequentially or simultaneously. In particular, the separation device can be configured for sequentially or simultaneously separating the first solar cell and the second solar cell into the two or more first solar cell pieces and the two or more second solar cell pieces, respectively. The positioning device 620 can be configured for positioning at least one second solar cell piece of the one or more second solar cell pieces on the support device 630 for forming the first solar cell arrangement together with the at least one first solar cell piece 17, and can be configured for positioning at least one other second solar cell piece of the two or more second solar cell pieces on the support device 630 for forming the second solar cell arrangement together with the at least one other first solar cell piece 19.

[0065] In particular, a plurality of solar cells can be divided into solar cell pieces, wherein each solar cell piece is allocated to either the first solar cell arrangement or the second solar cell arrangement. The solar cell pieces of the first solar cell arrangement can particularly include the at least one first solar cell piece 17 and the at least one second solar cell piece, and can optionally further include one or more solar cell pieces of further solar cells, such as a third, fourth, etc solar cell. The solar cell pieces, e.g., of the second solar cell arrangement can include the at least one other first solar cell piece and the at least one other second solar cell piece, and can optionally further include one or more solar cell pieces, e.g., of further solar cells, such as the third, fourth, etc solar cell.

[0066] In some implementations, the system 600 is configured to allocate each solar cell piece, such as the solar cell pieces of the two or more first solar cell pieces, to either the first solar cell arrangement or the second solar cell arrangement based on one or more properties (e.g., geometric and/or physical properties) of the respective solar cell piece. As an example, each solar cell piece of the plurality of solar cells can be allocated to either the first solar cell arrangement or the second solar cell arrangement, for example, based on one or more characteristics or properties of the respective solar cell piece. The one or more characteristics or properties of the solar cell piece may be selected from the group consisting of geometric shape, electrical properties, optical properties, printing quality, and any combination thereof.

[0067] In some implementations, the at least two solar cell arrangements, such as the first solar cell arrangement and the second solar cell arrangement, can be arranged in parallel (i.e., next to each other) on the support device 630, for example, along a transport direction provided by the support device 630. In particular, the at least two solar cell arrangements, such as the first solar cell arrangement and the second solar cell arrangement, can be assembled simultaneously by dividing the plurality of solar cells into solar cell pieces and selectively allocating the solar cell pieces to the first solar cell arrangement and the second solar cell arrangement.

[0068] Although the example of FIG. 6 shows two solar cell arrangements on the support device 630 that are assembled in parallel, it is to be understood that the present disclosure is not limited thereto, and that any number of solar cell arrangements could be assembled in parallel. As an example, the at least two solar cell arrangements can be two, three, four five, or even six solar cell arrangements, including the first solar cell arrangement and the second solar cell arrangement, that can be assembled in parallel. At least some of the solar cell arrangements can have different characteristics or quality based on the properties of the solar cell pieces which have been allocated to the individual solar cell arrangement.

[0069] According to some embodiments, which can be combined with other embodiments described herein, a solar cell arrangement, such as a shingled solar cell, can include two or more solar cell pieces.

[0070] FIG. 7 shows a schematic view of a solar cell arrangement 20, which is a shingled solar cell or hypercell, and that can be manufactured using the apparatuses, systems and methods according to the embodiments described herein. The solar cell arrangement 20 can be used in a solar cell module, which is a packaged, connected assembly of a plurality of solar cells or solar cell arrangements.

[0071] The shingled solar cell includes a plurality of overlapping solar cell pieces, such as the plurality of first solar cell arrangement pieces or the plurality of second solar cell arrangement pieces described with respect to FIG. 6. As an example, the shingled solar cell can include the at least one first solar cell piece 17 of the first solar cell and the at least one second solar cell piece 17' of the second solar cell. The at least one first solar cell piece 17 and the at least one second solar cell piece 17' overlap with each other. However, the present disclosure is not limited thereto and some of the adjacent solar cell pieces of the shingled solar cell can be from the same solar cell, such as the first solar cell or the second solar cell. Adjacent solar cell pieces can overlap by less than 20%, specifically less than 10%, and more specifically less than 5% of the total surface area, such as the f ontside surface or backside surface, of the solar cell pieces. [0072] In some implementations, each solar cell piece of the plurality of overlapping solar cell pieces of the solar cell arrangement 20 can have one or more conductive patterns, such as fingers 24 and/or busbars 23, provided thereon. As an example, the solar cell piece, such as the at least one first solar cell piece 17, can have a frontside and a backside corresponding to the frontside and the backside, respectively, of the former solar cell. Optionally, the solar cell piece can have one or more backside contacts. As exemplarily shown in FIG. 7, the at least one first solar cell piece 17 can have a first backside contact 25, and the at least one second solar cell piece 17' can have a second backside contact 25'.

[0073] Adjacent solar cell pieces are electrically connected to each other in the overlapping region. The solar cell pieces are thus connected in series such that current generated by the individual solar cell pieces flows along the series of solar cell pieces to be collected, for example, at an end portion of the solar cell arrangement 20 (not shown). The overlapping configuration can provide solar cell arrangements having an increased output power. As an example, the busbar 23 provided on the at least one first solar cell piece 17 can be electrically connected to the second backside contact 25' of the at least one second solar cell piece 17'. As shown in the example of FIG. 7, the separation device can be configured to separate the solar cell adjacent to the busbars of the solar cell. In other words, each solar cell piece can have a busbar, and particularly only one busbar, provided thereon, which can be located at an edge of the solar cell piece. [0074] In some implementations, an adhesive 27, such as an electrically conductive adhesive, can be provided to connect the solar cell pieces in the overlapping region. According to some embodiments, which can be combined with other embodiments described herein, the apparatus for the manufacture of at least two solar cell arrangements includes an adhesive application device configured to apply the adhesive to the solar cell or the solar cell pieces thereof, such as the two or more first pieces, before the two or more first solar cell pieces are positioned on the support device. Two solar cell pieces can be overlapped with the adhesive being provided at one solar cell piece of the two solar cell pieces such that the two solar cell pieces can be electrically and mechanically connected to each other. As an example, the adhesive can be in a substantially liquid form when the adhesive is applied to a solar cell or solar cell piece. [0075] According to some embodiments, the adhesive application device can be configured to apply the adhesive on at least a portion of the conductive line pattern, such as the busbars, of the solar cell or the solar cell pieces thereof. In some implementations, the adhesive is applied before the solar cell is divided into the two or more solar cell pieces. In other implementations, the adhesive is applied to the solar cell piece(s) after the solar cell has been divided into the two or more pieces.

[0076] According to some embodiments, the adhesive is selected from the group consisting of solder, silver paste, silicone-based electrically conductive adhesive, and epoxy-based electrically conductive adhesive. [0077] When solar cell pieces have been overlapped, for example, in the assembling of the solar cell arrangement, a drying process can be performed to dry the adhesive. In some implementations, the drying process can include a heating of the overlapping region of the two solar cell pieces using, for example, a heater such as an infrared heater. The heater is further explained with respect to FIG. 9. [0078] FIG. 8 A shows a schematic side view of a system for the manufacture of at least one shingled solar cell arrangement, such as two or more shingled solar cell arrangements, according to further embodiments described herein. FIG. 8B shows a schematic top view of the system. FIG. 9 shows a schematic view of overlapping solar cell pieces on a support device 630 according to embodiments described herein. [0079] According to some embodiments, which can be combined with other embodiments described herein, the system includes a transport device 650 configured for transportation of the solar cell pieces of the solar cell(s), such as the two or more first solar cell pieces of the first solar cell. The transport device 650 can be the second transportation device of the apparatus according to the present disclosure. In particular, the second transportation device can be configured as described in the following. In some implementations, the transport device 650 can include, or be, a belt conveyor having a roller 654 rotatable around a first rotational axis 656 and one or more first belts 652 provided on the roller 654. The transport device 650 can have two or more belts arranged in parallel and with gaps provided between the two or more belts. [0080] In some implementations, the first support and/or the second support of the support arrangement of the apparatus described with respect to FIGs. 1A, IB and 2 can be provided by the transport device 650, and particularly by the one or more first belts. The separation device is not illustrated in FIGs. 8A and B. [0081] According to some embodiments, the support device 630 can include, or be, a belt conveyor. The support device 630, e.g., the belt conveyor, can be configured to support, fix and transport the at least one solar cell arrangement, such as the first solar cell arrangement and the second solar cell arrangement. In particular, the support device 630 can be configured for transportation of the at least one solar cell arrangement in a transport direction 4, which can be an essentially horizontal direction.

[0082] The belt conveyor constituting the support device 630 can include a roller 636 rotatable around a second rotational axis 634 and one or more second belts 632 provided on the roller 636. In some implementations, the support device 630 can have two or more belts arranged in parallel and with gaps provided between the two or more belts. As an example, each belt of the two or more belts can be configured to support (only) one solar cell arrangement of two or more solar cell arrangements (for example, see FIG. 8A). In other implementations, the support device 630 has one single belt on which the two or more solar cell arrangements can be assembled in parallel (for example, see FIG. 8B).

[0083] According to some embodiments, which can be combined with other embodiments described herein, the support device 630 includes, or is, at least one of an electrostatic chuck and a vacuum chuck. The vacuum chuck can include a support surface configured to support the at least one solar cell arrangement, wherein the support surface can have at least one of holes and recesses connected to a suction device, such as a vacuum pump, in order to generate an under pressure in the holes and/or recesses to hold the solar cell arrangement at the support surface.

[0084] The at least one positioning device 620 is configured for moving or transferring the solar cell pieces of the solar cell from, for example, the transport device 650 to the support device 630. As an example, the positioning device 620 can sequentially grip or pick up the solar cell pieces from the transport device 650, move the solar cell pieces to the support device 630, optionally align the solar cell pieces, and release the solar cell pieces in a predetermined position. In particular, the positioning device 620 can be configured to arrange the solar cell pieces in an overlapping manner to form the first solar cell arrangement and the second solar cell arrangement. While the at least two solar cell arrangements are assembled on the support device 630, the support device 630, and particularly the one or more first belts having the (partially) assembled solar cell arrangements positioned thereon, can continuously move in the transport direction 4. A continuous manufacturing process can be provided.

[0085] According to some embodiments, the system includes a controller 640 configured to control the at least one positioning device 620. In particular, the controller 640 can control a movement of the positioning device 620 to move a solar cell piece to assemble a solar cell arrangement to which the solar cell piece has been allocated. As an example, the controller 640 can control the at least one positioning device 620 to move the solar cell piece to either the first solar cell arrangement or the second solar cell arrangement based on one or more properties (e.g., geometric and/or physical properties) of the piece, such as geometric shape, electrical properties, optical properties, printing quality, and any combination thereof.

[0086] According to some embodiments, which can be combined with other embodiments described herein, the at least one positioning device 620 includes a gripper 622 configured to grip and hold a solar cell piece, such as the two or more first pieces of the first solar cell. The gripper 622 can be selected from the group consisting of vacuum grippers, mechanical grippers, electrostatic grippers, electrodynamic grippers, and any combination thereof.

[0087] In some implementations, the positioning device 620 is movable in at least one of a first direction 1 and a second direction 2. The first direction 1 can be a substantially horizontal direction. The second direction 2 can be a substantially vertical direction. The positioning device 620 can be movable sequentially or simultaneously in at least one of the first direction 1 and the second direction 2. By the movement in the first direction 1 and the second direction 2, the solar cell piece held by the positioning device 620 can be moved to the support device 630 for assembling of a solar cell arrangement, such as the first solar cell arrangement and/or the second solar cell arrangement. [0088] As an example, the positioning device 620 can move in the second direction 2, for example, upwards, to pick up the solar cell piece from the transport device 650. The positioning device 620 can then move in the first direction 1, for example, forwards, to move the solar cell piece from the transport device 650 to the support device 630. The positioning device 620 can move in the second direction 2, for example, downwards, to place the solar cell piece on the support device 630. The positioning device 620 can then move in the second direction 2 and the first direction 1, for example, back to the transport device 650 to pick up another solar cell piece from the transport device 650. It is to be understood that the movement in the first direction 1 can be a movement in a forward direction and a backward direction. Likewise, the movement in the second direction 2 can be a movement in an upward direction and a movement in a downward direction.

[0089] The term "vertical direction" is understood to distinguish over "horizontal direction". That is, the "vertical direction" relates to a substantially vertical movement, wherein a deviation of a few degrees, e.g. up to 5° or even up to 10°, from an exact vertical direction is still considered as a" substantially vertical direction". The vertical direction can be substantially parallel to the force of gravity.

[0090] In some implementations, the system, and particularly the positioning device 620, can be configured for alignment of the solar cell piece held by the positioning device 620 before the solar cell piece is put on the support device 630. The system can use information acquired by an inspection system which can include, for example, a camera configured to detect a position and/or orientation of the solar cell piece, for example, held by the positioning device 620.

[0091] In some implementations, the positioning device 620 is movable in a plane, such as a substantially horizontal plane. Such a movement can also be referred to as "Θ movement". As an example, the positioning device 620 can be configured to adjust or align an angular orientation of a solar cell piece held by the positioning device 620 in the plane. The angular orientation of the solar cell piece can be aligned, for example, with respect to the support device 630 and/or another solar cell piece on the support device 630 with which the solar cell piece held by the positioning device 620 is to be overlapped. The solar cell arrangement can be accurately assembled, wherein a quality of the solar cell arrangement can be improved. In some implementations, the positioning device 620 can be configured to rotate the solar cell piece around a substantially vertical rotational axis by about 180°. In particular, edge pieces of pseudo-square solar cells can be brought into similar orientations. As an example, one edge piece (e.g., the front or leading edge piece) of the pseudo-square solar cell is not rotated by about 180° and the other edge piece (e.g., the back or trailing edge piece) of the pseudo-square solar cell is rotated by about 180° such that the geometric shapes of the edge pieces are equally oriented or aligned.

[0092] According to some embodiments, the positioning device 620 is tiltable, for example, with respect to the first direction 1 and/or a horizontal plane. As an example, the positioning device 620 can tilt the solar cell piece held by the positioning device 620 to align an orientation of the solar cell piece with respect to another solar cell piece on the support device 630 with which the solar cell piece held by the positioning device 620 is to be overlapped. In particular, the backside or backside plane of the solar cell piece held by the positioning device 620 can be oriented to be substantially parallel to a frontside or frontside plane of the other solar cell piece on the support device 630. In some implementations, the positioning device 620 is configured to align a backside contact of the solar cell piece with respect to a frontside contact, such as a busbar, of another solar cell piece on the support device 630 such that an electrical contact between the backside contact and the frontside contact can be established, for example, with an adhesive provided therebetween. [0093] As shown in FIG. 9, a plurality of solar cell pieces can be positioned on the support device 630 in an overlapping manner to form the solar cell arrangement, which can be a shingled solar cell. At least some of the plurality of pieces originate from at least two different solar cells. In particular, the solar cell pieces can be sorted and individually be allocated to a respective solar cell arrangement, for example, based on one or more properties, such as geometric and/or physical properties, of the respective solar cell piece.

[0094] In some implementations, the support device 630 is a belt conveyor having the one or more second belts 632. A movement of the belt conveyor, and in particular of the one or more second belts 632, and a movement of the at least one positioning device 620 can be synchronized with each other, for example, during the assembling of the at least two solar cell arrangements on the support device 630. Additionally or alternatively, a movement of the transport device 650, for example, the one or more first belts 652, and a movement of the at least one positioning device 620 and/or the one or more second belts 632 can be synchronized with each other. By synchronizing at least some of the movements, a continuous process flow for assembling of the at least two solar cell arrangements can be provided. [0095] According to some embodiments, which can be combined with other embodiments described herein, the system further includes a heating device 660, for example, at or above the support device 630. The heating device 660 can be configured to heat at least one of the solar cell arrangements on the support device 630, such as the first solar cell arrangement and/or the second solar cell arrangement. The heating device 660 can be selected from the group consisting of conduction heaters (e.g., hot plates), convective heaters, resistive heaters, infrared heaters, lamp heaters, hot air heaters, and any combination thereof. As an example, the support device 630 can be configured as a hot plate for conduction heat transfer to heat the solar cell arrangement(s) on the support device 630. [0096] In some implementations, the heating device 660 can extend along at least a portion of the support device 630, for example, in the transport direction 4 in which the solar cell arrangements are conveyed by the support device 630. The heating device 660 can extend along a distance sufficient to dry the adhesive used for electrically connecting adjacent overlapping solar cell pieces, such as the silver paste or solder. The heating device 660 can have two or more heating elements provided in parallel at the support device 630. As an example, a first heating element can be configured to heat the first solar cell arrangement. A second heating element can be configured to heat the second solar cell arrangement. In particular, according to some embodiments, the heating device 660 can extend above the support device 630 at positions corresponding to positions of the at least two solar cell arrangements. As an example, the first heating element can be arranged above the first solar cell arrangement, and the second heating element can be arranged above the second solar cell arrangement.

[0097] The heating device 660 can be configured to provide a predetermined temperature at the position of at least a portion of the solar cell arrangement. The predetermined temperature can be at least 100°C, specifically at least 150°C, and more specifically at least 300°C. The predetermined temperature can be in a range of between 100°C and 400°C, and can be specifically in a range of between 100°C and 200°C.

[0098] The solar cells that are divided into the two or more solar cell pieces can be selected from the group consisting of full-square solar cells and pseudo-square solar cells. The full-square solar cell can be, for example, a quadratic multi-crystalline wafer cut from silicon ingots. The pseudo-square solar cell can be a squared wafer with rounded edges cut from monocrystalline silicon ingots. In comparison with the full-square solar cell, the pseudo-square solar cell can be beneficial in that less waste is produced during the manufacturing process. [0099] The individual pieces of the solar cells can be allocated to different solar cell arrangements based on the geometrical shape. As an example, the (edge) pieces of the pseudo-square solar cell having the rounded edges ("pseudo-square pieces") can be allocated to one solar cell arrangement, for example, the first solar cell arrangement. The (middle) piece(s), which are full-square pieces, can be allocated to another solar cell arrangement, for example, the second solar cell arrangement. Specifically, solar cell arrangements having only full-square pieces or only pseud-square pieces are provided. "Bottlenecks" caused by a pseud-square piece in a solar cell arrangement having otherwise full-square pieces can be avoided and an efficiency of the solar cell arrangement can be increased. [00100] According to some embodiments, which can be combined with other embodiments described herein, the solar cells, such as the full-square solar cell and/or pseudo-square solar cell, can be separated or divided at positions adjacent to the busbars of the respective solar cell. In other words, each solar cell piece can have a busbar, and particularly only one busbar, provided thereon, which can be located at an edge of the solar cell piece.

[00101] FIG. 10A shows a schematic view of a production system 700 for the manufacture of at least one shingled solar cell according to embodiments described herein. The production system 700 can be part of, or constitute, a production line for shingled solar cells. [00102] The production system 700 includes the system for the manufacture of at least one solar cell arrangement, which can be a shingled solar cell arrangement, according to the embodiments described herein. The production system 700 further includes a production tool 710 for manufacturing a plurality of solar cells including the first solar cell. The plurality of solar cells are input into the system for the manufacture of at least one solar cell arrangement which includes the separation device 730, the positioning device 740, and the support device 750 according to the embodiments described therein.

[00103] In some implementations, the production tool 710 includes one or more printing devices configured for printing one or more conductive lines on solar cell substrates used in the manufacture of the plurality of solar cells. The one or more conductive lines are selected from fingers and busbars. The one or more printing devices can be configured for double printing of the one or more conductive lines. Specifically, the one or more printing devices can be configured for double printing of at least one of the fingers and busbars.

[00104] According to some embodiments, the production system 700 includes an adhesive application device 720 configured to apply an adhesive to the solar cell before the solar cell is separated into the two or more solar cell pieces. The adhesive is applied to portions of the solar cell corresponding to an overlapping region between two adjacent solar cell pieces that are arranged on the support device 750 in an overlapping manner. According to some embodiments, the adhesive application device 720 can be configured to apply the adhesive on at least a portion of the conductive line pattern, such as the busbars, of the solar cell.

[00105] According to some embodiments, which can be combined with other embodiments described herein, the separation device 730 includes the at least one solar cell perforation device. As an example, the at least one solar cell perforation device includes, or is, a laser. As an example, the at least one solar cell perforation device can be configured to perforate the solar cell before the solar cell is separated into the two or more solar cell pieces.

[00106] In some implementations, the production system 700 further includes a heating device 760, for example, subsequent to, or above, the support device 750. An embodiment of the heating device 760 is described with respect to FIG. 9. In particular, the heating device 760 can be configured to heat at least one of the solar cell arrangements to dry the adhesive in the overlapping region between two adjacent solar cell pieces. The heating device 760 can be selected from the group consisting of conduction heaters (e.g., hot plates), convective heaters, resistive heaters, infrared heaters, lamp heaters, hot air heaters, and any combination thereof.

[00107] According to some embodiments, which can be combined with other embodiments described herein, the production system 700 includes a sorting device 770 configured for sorting the at least two solar cell arrangements, such as the first solar cell arrangement and the second solar cell arrangement, based on a quality determination of the at least two solar cell arrangements. As an example, solar cell arrangements which are defective or have a low quality can be discarded. Optionally, defective solar cell arrangements can undergo a reworking or repair process, for example, to replace defective or low-quality solar cell pieces

[00108] FIG. 10B shows a schematic view of a production system 800 for the manufacture of at least one shingled solar cell arrangements, such as two or more shingled solar cell arrangements, according to further embodiments described herein. The production system 800 is similar to the system described with respect to FIG. 10A, and a description of similar or identical aspects is not repeated. In particular, the production system 800 includes the production tool 810, the adhesive application device 820, the heating device 860, and the sorting device 870.

[00109] According to some embodiments, which can be combined with other embodiments described herein, the production system 800 includes an inspection arrangement. The inspection arrangement can include at least one of a first inspection device 815, a second inspection device (may be included in the apparatus of the present disclosure, for example, in the positioning device 840), and a third inspection device 865. The first inspection device 815, the second inspection device, and the third inspection device 865 can be configured to determine and/or measure one or more properties, such as geometric and/or physical properties, of at least one of the solar cell, solar cell pieces and/or solar cell arrangement as described with respect to the embodiments described herein. In particular, the one or more properties can be selected from the group consisting of geometric shape, electrical properties, optical properties, printing quality, and any combination thereof.

[00110] In some implementations, the first inspection device 815 is configured to measure and/or determine one or more properties of a solar cell before the solar cell is separated into two or more solar cell pieces. Although the first inspection device 815 is exemplarily illustrated as being positioned between the production tool 810 and the adhesive application device 820, the present disclosure is not limited thereto. As an example, the first inspection device 815 can be provided between the adhesive application device 820 and the separation device 830 or can be integrated into the production tool 810, the adhesive application device 820, or the separation device 830.

[00111] According to some embodiments, the second inspection device is configured to measure and/or determine one or more properties of at least some of the solar cell pieces after the solar cell has been separated into pieces. The second inspection device can be integrated into the apparatus, for example, in the separation device 830 or the positioning device 840. In further implementations, the second inspection device can be provided as a separate entity.

[00112] In some embodiments, the third inspection device 865 is configured to measure and/or determine one or more properties of the at least one solar cell arrangement, such as the first solar cell arrangement and/or the second solar cell arrangement. Although the third inspection device 865 is exemplarily illustrated as being positioned between the heating device 860 and the sorting device 870, the present disclosure is not limited thereto. As an example, the third inspection device 865 can be provided at the support device 850. In some implementations, the support device 850, the heating device 860, and the third inspection device 865 are integrated in a single entity or process station. [00113] The present disclosure mechanically holds and separates a solar cell from the same side. A well-defined, smooth and accurate breaking edge can be achieved. A quality of the solar cell pieces used to assemble a solar cell arrangement, such as a shingled solar cell arrangement, can be improved and an output power can be increased. The separation process can provide for an increased yield and/or an increased throughput of a system for manufacturing the solar cell arrangement. [00114] While the foregoing is directed to embodiments of the disclosure, other and further embodiments of the disclosure may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
