Abstract
A multi-junction photoelectric conversion device includes, in the following order from a light-receiving side: a first photoelectric conversion unit; an intermediate layer; and a second photoelectric conversion unit. The first photoelectric conversion unit includes: a first light absorbing layer comprising a perovskite-type crystal structure photosensitive material; a first charge transport layer on the light-receiving side of the first light absorbing layer; and a second charge transport layer on a rear side of the first light absorbing layer. The second charge transport layer is in contact with the intermediate layer. The second photoelectric conversion unit includes: a second light absorbing layer that is a crystalline silicon substrate; and a first conductive semiconductor layer that is in contact with the intermediate layer.
