PROBLEM TO BE SOLVED: To provide a photoelectric conversion element of a perovskite type capable of obtaining excellent photoelectric conversion efficiency in a case of weak incident light such as room light (for instance, about 1000 Lux).SOLUTION: The photoelectric conversion element is formed by subsequently laminating on a conductive film substrate a first electrode provided with an electron transport layer, an inorganic semiconductor, a material having a perovskite type crystal structure represented by a general formula RNHM1X(R represents an alkyl group, M1 is a bivalent metal ion, and X represents a halogen atom), and P-type organic semiconductor. A structure part of a structural formula (A) below or a structural formula (B) of the P-type organic semiconductor contains a pyrrolopyrrole 3,6-dione derivative or a dithiophene derivative.SELECTED DRAWING: Figure 1 |
