The invention discloses a photoelectric conversion element, a solar battery, and a composition. Provided is a photoelectric conversion element having a first electrode that has, on a conductive support body, a photosensitive layer containing a light absorber, wherein the light absorber contains a compound having a Perovskite crystal structure that has an organic cation represented by formulas (1)and (2), a cation of a metal element, and an anion. Further provided are a solar battery using the photoelectric conversion element, and a composition. Formula (1): R1-N(R1a)3 +. Formula (2): R2-N(R2a)3 +. In the formulas, R1 represents a specific group such as an alkyl group (if the alkyl group has a carbon number of 1 or 2, the alkyl group has a specific substituent) or a cycloalkyl group, R2 represents a methyl group, an ethyl group, or the like, and R1a and R2a represent a specific group such as a hydrogen atom or an alkyl group.
