The A represents at least one selected from a monovalent cation of a metal element and a monovalent cation of an amine compound. The B represents a bivalent cation of a metal element. The X represents a monovalent anion of a halogen element. The number of molecules of the solvent with respect to one crystal lattice of the perovskite compound ranges from 0.004 to 0.5.
