Title:
METHOD FOR MANUFACTURING SOLAR CELL
Document Type and Number:
WIPO Patent Application WO/2010/023845
Kind Code:
A1
Abstract:
Provided is a method for manufacturing a solar cell wherein a photoelectric conversion body, which has a first electrode layer, a semiconductor layer and a second electrode layer stacked therein in this order, is formed on one surface of a substrate, a connecting portion between the first electrode layer and the second electrode layer is provided, the photoelectric conversion body has a plurality of separated elements which are electrically separated by scribe lines having the semiconductor layer and the second electrode layer removed therefrom, and the separated elements adjacent to each other are electrically connected. The method is provided with a defective region specifying step of specifying a region where a structural defect of the photoelectric conversion body exists, and a repair step of removing or separating the structural defect by irradiating the photoelectric conversion body with a laser beam, forming three repair lines each of which has the semiconductor layer and the second electrode layer removed therefrom, and surrounding the region where the structural defect exists by using the three repair lines and the one scribe line. In a region (α) including a contact section where the semiconductor layer is in contact with the substrate in a region between the structural defect and the connecting section in the photoelectric conversion body, one repair line among the three repair lines is formed.
