ABSTRACT:
A solar cell includes an insulating or semi-insulating substrate having a pair of through holes, an n type semiconductor layer disposed on the front surface of the substrate, and a p type semiconductor layer disposed on the substrate in the first hole and on the n type semiconductor layer. An n side electrode is formed on the surface of the n type semiconductor layer in the second hole and also on a part of the back surface of the substrate. A p side electrode is formed on the surface of the p type semiconductor layer in the first hole and also on the back surface of the substrate. In connecting a plurality of solar cells in a wafer in series, a trench reaching the substrate is formed between adjacent solar cells.
