Photoelectric conversion element and solar cell module

A photoelectric conversion element, comprising:

• a first electrode;
• a photoelectric conversion layer, where the photoelectric conversion layer has a perovskite structure;
• a hole-transporting layer;
• a second electrode;
• and
• a film including a compound represented by General Formula (2) disposed between the photoelectric conversion layer and the hole-transporting layer,
• A-X General Formula (2)
• where, in General Formula (2), A is a cationic amino compound represented by General Formula (6), General Formula (7), a cationic imidazolinium compound, or a cationic pyrrolidinium compound,
• where, in General Formula (7), n is an integer of 5 or greater but 12 or less, and X is Br or I,
• where, in General Formula (6), R1 is —H, —F, —CF3, or —OCH3, n is 1 or 2, and X is Br or I, and
• wherein the hole-transporting layer comprises a compound represented by General Formula (4) and a compound represented by General Formula (5);
• where, in General Formula (4), R5 is a methyl group or a methoxy group, R6 and R7 are each an alkoxy group, and n is an integer of 2 or greater,
• where, in General Formula (5), R5 to R9 are each a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, or an aryl group, where R5 to R9 may be identical or different, and X is a cation.
