Title:
PROCESS FOR PRODUCING SOLAR CELL
Document Type and Number:
WIPO Patent Application WO/2012/014806
Kind Code:
A1
Abstract:
The objective of this invention is to provide a solar cell having excellent output characteristics without damaging the pn junction thereof at the time of forming electrodes by screen printing. The present invention involves: forming an electrode (5) by screen printing on the lower surface of a substrate (1) that has a pn junction, which contributes to the generation of electricity, on the lower-surface side thereof; and then forming an electrode (9) by screen printing on the upper-surface side, which is opposite from the lower surface, of the substrate (1). The electrodes (5, 9) comprise finger electrodes, and the number of finger electrodes in the electrode (5) is larger than the number of finger electrodes in the electrode (9).
