Title: SOLAR CELL
Abstract:
The purpose of the present invention is to provide a solar cell having excellent photoelectric conversion efficiency, little deterioration during sealing (initial deterioration), high-temperature durability, and excellent temperature cycle durability. This solar cell has: a laminate having an electrode, a counter electrode, and a photoelectric conversion layer arranged between the electrode and the counter electrode; and a sealing material covering the counter electrode and sealing the laminate. The photoelectric conversion layer includes an organic-inorganic perovskite compound indicated by general formula R-M-X3 (R indicating an organic molecule, M indicating a metal atom, and X indicating a halogen atom or a chalcogen atom.) The sealing material includes a (meth) acrylic resin having a C atom/O atom ratio in the molecules thereof of at least 4.
