摘要

The main aim of this invention is to provide a dye-sensitized solar cell element that has superior design properties, has a simple manufacturing process, and has high power generation efficiency. The present invention solves the problem described above by providing a dye-sensitized solar cell element in which an oxide semiconductor electrode substrate that has a first electrode substrate providing the function of an electrode and an oxide semiconductor layer that holds a dye-sensitizing agent on the surface of the oxide semiconductor film that is formed on the first electrode substrate and includes metal oxide semiconductor particles, and a counter electrode substrate having a second electrode substrate providing at least the function of an electrode are arranged so that the oxide semiconductor layer is opposite the second electrode substrate; and an electrolytic layer including an oxidation-reduction pair is formed between the oxide semiconductor electrode substrate and the counter electrode substrate, wherein the oxide semiconductor layer has at least two regions having different film thicknesses and different transmittances; at least two of these regions are formed into one body; in the oxide semiconductor layer, the color tone in the region having a thick film is darker; and the color tone in the region having a thin film is lighter compared to the color tone of the region having the thick film.
