PHOTOELECTRIC CONVERSION ELEMENT AND PHOTOELECTRIC CONVERSION ELEMENT MODULE

摘要

Provided is a photoelectric conversion element which has: a translucent substrate; a transparent conducting layer formed on the translucent substrate; a photoelectric conversion layer formed on the transparent conducting layer; a porous insulating layer formed in contact with the photoelectric conversion layer; a reflecting layer formed in contact with the porous insulating layer; and a catalyst layer and a counter electrode conducting layer, which are formed on the reflecting layer. The photoelectric conversion layer includes a porous semiconductor, a carrier transporting material, and a photosensitizer. Each of the projection area, which is obtained when the porous insulating layer is perpendicularly projected toward the translucent substrate, and the projection area, which is obtained when the reflecting layer is perpendicularly projected toward the translucent substrate, is larger than the projection area obtained when the photoelectric conversion layer is perpendicularly projected toward the translucent substrate. A photoelectric conversion element module using the photoelectric conversion element is also provided.
