SOLAR CELL AND SOLAR CELL MANUFACTURING METHOD

The present invention aims to provide a solar cell in which a decrease in photoelectric conversion efficiency due to continuous exposure to light (photodegradation) is reduced, and a method of producing the solar cell. The present invention relates to a solar cell, including: an electrode; a counter electrode; and a photoelectric conversion layer between the electrode and the counter electrode, the photoelectric conversion layer containing an organic-inorganic perovskite compound represented by the formula R-M-X 3 where R is an organic molecule, M is a metal atom, and X is a halogen atom or a chalcogen atom, the solar cell satisfying the formula (1): N T I / N 0 I < 5 where N(0, I) is a carrier density of the organic-inorganic perovskite compound immediately after start of exposure of the solar cell to light at an intensity of I mW/cm 2 , and N(T, I) is the carrier density of the organic-inorganic perovskite compound after continuous exposure of the solar cell to light at an intensity of I mW/cm 2 for T hour/hours.
