PROBLEM TO BE SOLVED: To provide an organic solar cell having high photoelectric conversion efficiency.SOLUTION: An organic solar cell (1) includes an electron-donating layer (12) laminated on a lower electrode (10), an electron-accepting layer (14, 16, 17, 18), and a counter electrode (20). The organic solar cell (1) includes a photoelectric conversion layer in which the electron-donating layer (12) and the electron-accepting layer (14, 16, 17, 18) containing electron-accepting materials being three or more organic materials are laminated. The electron-accepting layer (14, 16, 17, 18) is composed of a plurality of layers including a layer in which at least two of the three or more electron-accepting materials are mixed. |
