Photoelectric conversion element and photoelectric conversion device

Abstract

Provided are a photoelectric conversion element and a photoelectric conversion apparatus each of which achieves both of a high open circuit voltage and high durability. The photoelectric conversion element includes: a first electrode; a second electrode; and a photoelectric conversion layer arranged between the first electrode and the second electrode, the photoelectric conversion layer containing a crystal having a perovskite structure. The photoelectric conversion element is characterized by further including, between the photoelectric conversion layer and the first electrode, a charge-transporting layer containing: a crystal of a cyclic conjugated compound in which pyrrole rings are bonded by conjugated bonds, the compound having an axial ligand; and a resin having a Lewis basic functional group.
