Photoelectric conversion element and solar battery module

Abstract

The photoelectric conversion element includes a surface electrode, a backside electrode, a light absorption layer disposed between the surface electrode and the backside electrode, and a hole transport layer disposed between the backside electrode and the light absorption layer. The light absorption layer contains a conical or elliptical conical crystal. The crystal has a perovskite layer containing a perovskite compound. The hole transport layer contains an inorganic material. A solar battery module includes a plurality of photoelectric conversion elements connected in series. The photoelectric conversion elements are the aforementioned photoelectric conversion element.
