Solar cell
Abstract:
The present invention aims to provide a solar cell that includes a photoelectric conversion layer containing an organic-inorganic perovskite compound and that can exhibit high photoelectric conversion efficiency and high heat resistance. Provided is a solar cell including, in the stated order: a cathode; a photoelectric conversion layer; and an anode, the photoelectric conversion layer containing an organic-inorganic perovskite compound represented by the formula R-M-X3 where R is an organic molecule, M is a metal atom, and X is a halogen atom or a chalcogen atom, and a polymer having an acid dissociation constant pKa of 3 or less.
