Abstract: The present disclosure provides a photoelectric conversion film having a high light absorption ability and a long carrier life. A photoelectric conversion film of the present disclosure includes a perovskite compound including a monovalent formamidinium cation, a Pb cation and an iodide ion. The film thickness of the photoelectric conversion film is greater than or equal to 1 μm. In the photoelectric conversion film, the ratio of root mean square roughness Rq to the film thickness is less than or equal to 0.13.

Abstract: The present disclosure is to provide a multi-junction light energy conversion element including a material having a band gap suitable for a light energy conversion layer located upstream in an incidence direction of light. The present disclosure provides a light energy conversion element, comprising a first light energy conversion layer containing SrZn2N2 and a second light energy conversion layer containing an light energy conversion material. The light energy conversion material has a narrower band gap than the SrZn2N2.
