PROBLEM TO BE SOLVED: To provide a photoelectric conversion element which reduces variation of photoelectric conversion efficiency and exerts stable battery performance, and a solar cell having the same.SOLUTION: A photoelectric conversion element comprises: a first electrode having a photosensitive layer containing a light absorption agent on a conductive support; a second electrode opposed to the first electrode; and a hole transport layer between the first electrode and the second electrode, and in the photoelectric conversion element, the light absorption agent contains at least one kind of compound(P) having the perovskite crystal structure represented by the following formula (I). A solar cell has the photoelectric conversion element. In the formula (I):A(MM)X, A represents a cationic group represented by R-NH. Mand Mrepresent each different metal atoms, n represents an integer of 0≤n≤0.5, and X represents an anionic atom. a represents 1 or 2, mA represents 1, a, mA and X satisfy a+2mA=x. Rmay have a substituent group. |
