Abstract
A solar cell includes a photoelectric conversion section that, includes an n-type crystal silicon substrate, a p-type silicon-based thin-film provided on a first principal surface, and an n-type silicon-based thin-film provided on a second principal surface, and further includes a first electrode layer on the p-type silicon-based thin-film, and a second electrode layer on the n-type silicon-based thin film. A patterned collector electrode is provided on the first electrode layer. On the first principal surface of the photoelectric conversion section, a wraparound portion of the second electrode layer, an insulating region where neither the first electrode layer nor the second electrode layer is provided, and a first electrode layer-formed region are arranged in this order from a peripheral end.
