Title:
Dye-sensitized solar cell
Document Type and Number:
Japanese Patent JP6218046
Kind Code:
B2
Abstract:
Provided is a dye-sensitized solar cell which exhibits excellent heat resistance and high photoelectric conversion efficiency. This dye-sensitized solar cell is provided with: a negative electrode having a semiconductor layer with a pigment as a photosensitizer, an electrolyte layer located on the semiconductor layer of the negative electrode having a paired oxidized species and reduced species, and a positive electrode located on the electrolyte layer having a conductive polymer layer that acts as a catalyst to convert the oxidized species into the reduced species. The conductive polymer layer in the positive electrode contains a polymer derived from at least one monomer selected from the group consisting of 3,4-disubstituted thiophenes; and an anion as a dopant to the polymer generated from at least one organic non-sulfonate compound having an anion with the molecular weight of 200 or more. The thickness of the conductive polymer layer is within the range of 100 to 10000 nm.
