Abstract
A thin-film solar cell having a first solar cell layer with a plurality of unit cells including a photoelectric conversion layer that are connected in series; a second solar cell layer with a plurality of unit cells including a photoelectric conversion layer that are connected in series, and that has band gap energy different from the first solar cell layer and a threshold voltage coincident with the first solar cell layer; and an electrode connector, that connects the first solar cell layer with the second solar cell layer in parallel.
