MASK FOR FORMING A FRONT ELECTRODE OF A SOLAR CELL

WIPO Patent Application WO/2011/021811

A2

The present invention relates to a mask for forming a front electrode of a solar cell, wherein a reduction in local areas in the intersecting portion between a busbar and finger lines is prevented during the formation of the front electrode of the solar cell, to thereby improve photoelectron conversion efficiency. The mask for forming a front electrode of a solar cell according to the present invention comprises: a main body having an area corresponding to the plane of the solar cell; and an opening which is formed in the main body and which has a shape corresponding to the circuit line of the front electrode of the solar cell. The front electrode comprises a busbar and a plurality of finger lines, wherein the busbar is vertically arranged and the finger lines are horizontally connected to the busbar. The opening has a busbar pattern and a finger line pattern with shapes corresponding to the busbar and the finger lines, respectively. The opening extends in the diagonal direction between the busbar pattern and the finger line pattern, in the portion at which the busbar pattern and the finger line pattern perpendicularly intersect.
