[PROBLEMS] To provide an organic dye-sensitized solar cell capable of efficiently using solar energy. A transparent substrate having a transparent electrode on its surface, a metal oxide semiconductor film formed on the transparent electrode, and an organic dye-sensitized metal oxide containing an organic dye adsorbed on the surface of the semiconductor film. In the semiconductor electrode, an antireflection film 7 is provided on the surface of the transparent substrate on which the transparent electrode is not provided. Preferably, an organic dye-sensitized metal oxide semiconductor electrode is provided with an antireflection film comprising an alternately laminated film of a high refractive index film and a low refractive index; and a solar cell. |
