A dye-sensitized solar cell of the present invention including: an electrode having, on one surface, a semiconductor layer with a sensitizing dye supported thereon, a counter electrode positioned opposing the semiconductor layer, and a charge transport layer disposed between the electrode and the counter electrode, wherein at least one of the electrode and the counter electrode is a transparent conductive film prepared by laminating an ITO film and an FTO film, and part or all of the crystal structure of the surface of the FTO film is orthorhombic.

Dye-sensitized solar cell

A photoelectric element provided with an electron transport layer having excellent electron transport property and sufficiently wide reaction interface, and that has excellent conversion efficiency. The photoelectric element has an electron transport layerand a hole transport layersandwiched between a pair of electrodesand. The electron transport layeris formed of an organic compound having a redox moiety capable of being oxidized and reduced repeatedly. The organic compound contains an electrolyte solution which stabilizes the reduced state of the redox moiety, and forms a gel layercontaining a sensitizing dye. Thus, the organic compound and the electrolyte solution in the electron transport layerconstitute the gel layer, while at the same time, the sensitizing dye is present within the gel layer, whereby the reaction interface of the organic compound is enlarged, improving the conversion efficiency and the electron hand-over efficiency from the sensitizing dye to the organic compound in the electron transport layer, as a result of which the electron transport efficiency is improved.
