Abstract

A photoelectric conversion element includes a first electrode which has a porous layer provided on a conductive support and a photosensitive layer having a light absorber on a surface of the porous layer, a second electrode which is opposed to the first electrode, and a solid hole transport layer which is provided between the first electrode and the second electrode. The light absorber includes a compound having a perovskite crystal structure having a cation of a group I element of the periodic table or a cation of a cationic organic group A, a cation of a metal atom M other than the group I elements of the periodic table, and an anion of an anionic atom X, and the porous layer contains at least one of insulating material. A solar cell includes this photoelectric conversion element.
