A photoelectric conversion element and solar cell

A photoelectric conversion element includes a first electrode having an opening provided on a conductive substrate porous layer and a light-sensitive layer comprising a light absorber on a surface of the porous layer, a second electrode opposite the first electrode, and a solid hole transporting layer disposed between the first electrode and the second electrode is provided. The light absorber includes a compound having a perovskite crystal structure, a cation of an element of Group I of the periodic table or a cation of a cationic organic group A, a cation of a metal atom M, which is different from the elements of Group I of the Periodic Table, and has an anion X of an anionic atom, and the porous layer contains at least one insulating material. A solar cell includes a photoelectric conversion element of this.
