PURPOSE:To provide an organic photovoltaic element having preferable rectifying and photovoltaic characteristics by forming a pn-junction upon formation of a charge transfer complex on the surface of an organic semiconductor and making contact with metal at the junction. CONSTITUTION:An n-type electron receiving substance is coated or laminated on a p-type organic semiconductor, or a p-type electron receiving substance is coated or laminated on an n-type organic semiconductor to form a charge transfer complex on the surface of the organic semiconductor. Then, a metal becoming conductive layer is brought into contact with both front and back surfaces of the laminate. That is, an n-type organic semiconductor layer 4 is laminated on the p-type organic semiconductor layer 3 to form a charge transfer complex 5 in the boundary therebetween, and a conductor layer 1 such as gold, indium oxide or the like is coated on both front and back surfaces of thereof. The layer 3 may, for example, employ poly-n-vinylcarbazole, ploy(gamma-(P-N-carbazolylethyl)-L-glutamate) or the like, and the layer 4 may, for example, employ 2,4,7-trinitrochlorine. |
