Title: Dye-sensitized solar cell and manufacturing method for the same
Inventor: TAZAWA KOJI
IPC: H01G9/20
Filed: 2019-10-03
Abstract: To improve the reliability and the productivity of a dye-sensitized solar cell.SOLUTION: In a monolithic type dye-sensitized solar cell 1, on a substrate 11 with a flat surface being transparent to the wavelength of a solar cell on a light incidence side, at least a transparent electrode layer 12, a porous semiconductor layer, a porous insulating layer 13, and a back electrode layer 14 are sequentially stacked. The porous semiconductor layer adsorbs dye. An electrolyte solution 18 is sealed in an internal space 17 formed between a cover 16 and the substrate 11. The internal space 17 is formed not by the conventional walls of a pair of flat substrates and a sealing material formed in a peripheral part but by a concave part 19 engraving a glass plate on the cover 16 side. Therefore, since the height of the internal space 17, that is, the total film thickness of the respective layers is secured by the engraving depth of the cover 16, the sealing material 15 can be made very thin.SELECTED DRAWING: Figure 1
