Abstract

A photoelectric conversion element including a first electrode which has a photosensitive layer containing a light absorber on a conductive support, a second electrode which is opposed to the first electrode, and a hole transport layer which is provided between the first electrode and the second electrode, in which 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 cationic organic group, 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 hole transport layer contains a hole transport material of which the energy level of the highest occupied molecular orbital obtained by density functional theory calculation is within a range of −4.50 eV to −5.00 eV, and a solar cell including the photoelectric conversion element.
