Abstract: PROBLEM TO BE SOLVED: To provide a stacked organic solar cell which has high power generation efficiency and can prevent a lower metal layer from being subjected to the action of a solvent when forming a metal layer by applying a solution on the lower metal layer. SOLUTION: A power generation layer 1 formed by applying a solution containing a donor material and an acceptor material is disposed on a surface of the other power generation layer 2 via an adhesive layer 3. Further, the adhesive layer 3 is formed of at least one layer selected from a layer made of transparent oxide, a layer made of transparent nitride, and a transparent layer made of 14th group elements. When the power generation layer 1 is formed by applying the solution containing the donor material and the acceptor material, the action of the solution on the surface of the other power generation layer 2 can be blocked and prevented by the adhesive layer 3. Moreover, the adhesive layer 3 is made of the transparent oxide, the transparent nitride, or the 14th group elements, so that the adhesive layer 3 can be formed as a transparent and dense film. It is thus possible to secure a transmittance of light and achieve high power generation efficiency. COPYRIGHT: (C)2007,JPO&INPIT
