Zusammenfassung:Provided are a photoelectric conversion element including a first electrode having a photosensitive layer including a light absorber on a conductive support and a second electrode facing the first electrode, in which the light absorber includes a compound having a perovskite-type crystal structure and at least one compound selected from compounds represented by any formula of Formulae (3) to (5) below is provided on a surface of the first electrode, a solar cell, and a method for manufacturing a photoelectric conversion element. In the formulae, G 1 to G 4 represent a group or a salt selected from the group consisting of -OR a , -O - Ya + , -SR a , -S - Ya + , -NR a R b , and -(NR a R b R c ) + Ya - . R a , R b , and R c represent a hydrogen atom or a substituent. Ya represents a counter salt. L 1 represents an alkyl group, a cycloalkyl group, or the like. J 1 and J 3 represent a single bond or a linking group. J 2 represents a linking group. p1 and p2 represent an integer of 1 or higher. A ring C represents an aromatic hydrocarbon ring or an aromatic hetero ring. Z represents a hetero atom or NR 12 . R 12 represents a hydrogen atom or a substituent. m, n12, and n13 represent an integer of 0 or higher. R 11 represents a substituent. n 1 1 and q represent an integer of 1 or higher.
