Abstract

The present invention makes it possible to provide a stacked-type thin-film photoelectric conversion device having high photostability, at a high yield rate and significantly reduced production costs. In a stacked-type photoelectric conversion device having an amorphous silicon-based photoelectric conversion unit and a crystalline silicon-based photoelectric conversion unit stacked thereon or vice versa, an amorphous photoelectric conversion layer included in the amorphous photoelectric conversion unit has a thickness of at least 0.03 μm and less than 0.17 μm, a crystalline photoelectric conversion layer included in the crystalline photoelectric conversion unit has a thickness of at least 0.2 μm and less than 1.0 μm, and a silicon oxide layer of a first conductivity type included in the amorphous photoelectric conversion unit and a silicon layer of a second conductivity type included in the crystalline photoelectric conversion unit make a junction.
