Disclosed are: an organic photoelectric conversion element or solar cell, which has high fill factor, high open circuit voltage, high photoelectric conversion efficiency and durability; and an organic semiconductor material which constitutes the organic photoelectric conversion element. Specifically disclosed is an organic photoelectric conversion element which comprises a negative electrode, a positive electrode, and a bulk heterojunction layer wherein a p-type semiconductor material and an n-type semiconductor material are mixed together. The organic photoelectric conversion element is characterized by having a layer, which is formed from a material that has a LUMO level lower than -1.4 eV and a glass transition temperature (Tg) of 50-280°C (inclusive), between the negative electrode and the bulk heterojunction layer. |
