MATERIAL COMPOSITION FOR ORGANIC PHOTOELECTRIC CONVERSION LAYER, ORGANIC PHOTOELECTRIC CONVERSION ELEMENT, METHOD FOR PRODUCING ORGANIC PHOTOELECTRIC CONVERSION ELEMENT, AND SOLAR CELL

摘要

The purpose of the present invention is to provide a material composition for a bulk heterojunction-type organic photoelectric conversion layer, an organic photoelectric conversion element, a method for producing the same, and a solar cell that with a short drying time forms a stable, phase-separated structure, has high photoelectric conversion efficiency and durability, and has high productivity. This material composition for an organic photoelectric conversion layer is characterized in that a solvent represented by formula (1) is used in a material composition for an organic photoelectric conversion element comprising at least a p-type conjugate polymer semiconductor material that is a copolymer having electron donating groups and electron withdrawing groups in the main chain, an electron-accepting n-type organic semiconductor material and a solvent.
