Patent ID: 8253011

Claim:
A solar cell fabricating method comprising at least: forming an antireflection coating at a front surface of a semiconductor substrate having a pn junction; forming a front surface electrode at the antireflection coating; and forming a back surface electrode on a back surface of the semiconductor substrate; wherein at least the front surface electrode is formed by an electrode forming method for an electrode having a multi-layered structure on a semiconductor substrate by screen-printing by using a conductive paste including at least silver powder, glass frit, an organic vehicle, and an organic solvent, comprising: forming a first electrode layer joined directly to the semiconductor substrate; and forming an upper electrode layer constituted of at least one layer on the first electrode layer; wherein the conductive paste for the upper electrode layer, for forming the upper electrode layer, has a total silver content of 75 wt % or more and 95 wt % or less, and a content of silver particles having an average particle diameter of 4 or greater and 8 μm or smaller with respect to the total silver content in the conductive paste for the upper electrode layer is higher than that in the conductive paste for the first electrode layer; and the upper electrode layer has a same footprint as the first electrode layer.
