This invention has an objective of producing the organic solar cell having the long life. The organic solar cell of this invention comprises a first electrode collecting holes, a second electrode collecting electrons, mixing layer interposed between the first electrode and the second electrode and having an electron donating semiconductor and the electron accepting semiconductor, and a first electron transport layer and a second electron transport layer interposed between the mixing layer and the second electrode. With this invention, the adhesiveness in the boundary between the mixing layer and the second electrode is improved. Consequently, it is possible to prevent the mixing layer from accumulating the electrical charge generated by absorbing the light. Therefore, the electrical charge is efficiently moved to the second electrode and the long life is achieved. |
