NOVELTY - Photosensitized solar cell includes a current collector wiring made of metal and provided on an inclined wall surface of a groove, transparent electrode layer provided in a region other than the groove on the substrate, a semiconductor layer provided on the transparent electrode layer and current collector wiring, and semiconductor electrode provided on the semiconductor layer and carrying a dye.    USE - For generating power.    ADVANTAGE - The solar cell is capable of obtaining high energy conversion efficiency. The current collector wiring can be arranged uniformly in the inner surface of the groove so that conduction is maintained between the electrode layer and the current collector wiring. The iodine and the metal of the current collector wiring may react and the metal may elute into the electrolyte.
