Provided are an organic-inorganic hybrid junction device in which organic and inorganic materials are connected by junction, and a depletion layer is formed at a junction interface, and an organic photovoltaic cell using the same. A basic metal oxide solution is applied to a top surface of a P-doped organic layer. The basic metal oxide solution has N-type characteristics. An oxidation-reduction reaction occurs in response to the application of the basic metal oxide solution at a junction interface of the organic layer, and the metal oxide layer is simultaneously gelated. A free charge is removed from a surface region of the P-doped organic layer by the oxidation-reduction reaction at the interface, which is converted into a depletion region. According to the introduction of the depletion region, P-N junction occurs, and thus the device has a diode characteristic in an electrical aspect. Also, an organic photovoltaic cell including the organic layer, the depletion layer and the metal oxide layer is fabricated. |
