发明名称 Semiconductor substrate, method for forming electrode, and method for fabricating solar cell
摘要 The present invention is directed to a semiconductor substrate having at least an electrode formed thereon, in which the electrode has a multilayer structure including two or more layers, of the multilayer structure, at least a first electrode layer directly bonded to the semiconductor substrate contains at least silver and a glass frit, and contains, as an additive, at least one of oxides of Ti, Bi, Zr, V, Nb, Ta, Cr, Mo, W, Mn, Fe, Co, Ni, Si, Al, Ge, Sn, Pb, and Zn, and, of an electrode layer formed on the first electrode layer, at least an uppermost electrode layer to be bonded to a wire contains at least silver and a glass frit and does not contain the additive. This makes it possible to form, on a semiconductor substrate, an electrode adhered to the semiconductor substrate with sufficient adhesive strength and adhered to a wire via solder with sufficient adhesive strength by lowering both contact resistance and interconnect resistance.
