摘要
It is an object of the present invention to provide a material composition for a bulk-heterojunction-type organic photoelectric conversion layer having high photoelectric conversion efficiency and durability through formation of a stable phase-separated structure by drying in a short time with high productivity and to provide an organic photoelectric conversion element, a method of producing the organic photoelectric conversion element, and a solar cell. The material composition for an organic photoelectric conversion layer contains at least a p-type conjugated polymer semiconductor material being a copolymer having a main chain including an electron-donating group and an electron-withdrawing group, an n-type organic semiconductor material having electron acceptability, and a solvent. The solvent is represented by a general formula (1).
