NOVELTY - The dye sensitized solar cell, comprises a transparent conductive oxide (23) including a transparent substrate (21) and a conductive metal oxide having a light transmission property, a metal grid (81) formed on the transparent conductive oxide, a protective film, a dye-adsorbed semiconductor thin film formed on the transparent conductive oxide in which the metal grid is not formed, and a counter electrode substrate. The metal grid is coated with the protective film. A short-circuit preventing layer is provided on the counter electrode substrate facing the metal grid.    USE - Used as a dye sensitized solar cell.    ADVANTAGE - The dye sensitized solar cell has a high photoelectric conversion efficiency and a short-circuit preventing structure with increased thickness and can be economically manufactured with light weight.    DETAILED DESCRIPTION - The dye sensitized solar cell, comprises a transparent conductive oxide (23) including a transparent substrate (21) and a conductive metal oxide having a light transmission property, a metal grid (81) formed on the transparent conductive oxide, a protective film, a dye-adsorbed semiconductor thin film formed on the transparent conductive oxide in which the metal grid is not formed, and a counter electrode substrate. The metal grid is coated with the protective film. A short-circuit preventing layer is provided on the counter electrode substrate facing the metal grid. A width formed by a short side of the short-circuit preventing layer is larger than a width formed by the metal grid and protective layer (82). The short-circuit preventing layer contacts the protective layer or dye-adsorbed semiconductor thin film. A metal and a resin substrate are used in a part of the counter electrode substrate. The counter electrode substrate includes metal or a catalytic layer. The metal promotes catalytic action of a redox mediator. The catalytic layer is made of an organic compound. The counter electrode substrate has an irregular structure and is made of a metal formed by die press or machining. A distance in a height direction formed by the metal grid and protective film is larger than a distance between the counter electrode substrate and the dye-adsorbed semiconductor thin film. A projection of the counter electrode substrate exists between the metal grid and the protective film adjacent to each other. An electrolytic solution is included in a part of a gap between the electrodes.    DESCRIPTION OF DRAWING(S) - The diagram shows a sectional view of a dye sensitized solar cell.
