Photoelectric conversion element and solar cell

A photoelectric conversion element comprising:

• a first electrode having a photosensitive layer including a light absorber on a conductive support;
• and
• a second electrode facing the first electrode,
• wherein the light absorber includes a compound having a perovskite-type crystal structure including cations of an element belonging to Group I of the periodic table or organic cations, cations of a metallic atom other than elements belonging to Group I of the periodic table, and anions, and
• at least some of the anions constituting the compound are organic anions represented by Formula (An),
• R1—C(═X1)—X2 Formula (An)
• in the formula, R1 represents a hydrogen atom, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, a heteroaryl group, an aliphatic heterocyclic group, —N(R2)2, —OR3, —SR4, or a halogen atom, X1 represents an O atom or a S atom, R2 to R4 represent alkyl groups or aryl groups, and X2 represents O− or S−,
• here, in a case in which X1 is an O atom and X2 is O−, the alkyl group is a substituted methyl group or an alkyl group having two or more carbon atoms.
