Patent ID: 8354584

Claim:
A dye sensitized solar cell comprising: a transparent conductive oxide which includes a transparent substrate and a conductive metal oxide having a light transmission property; a metal grid which is formed on the transparent conductive oxide; a protective layer with which the metal grid is coated; a dye-adsorbed semiconductor thin film which is formed on the transparent conductive oxide in a region in which the metal grid is not formed; and a counter electrode substrate which is provided with an injection hole for injecting an electrolytic solution, wherein the electrolytic solution is injected between the transparent conductive oxide and the counter electrode substrate, wherein a short-circuit preventing layer is provided on the counter electrode substrate facing the metal grid, and 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, wherein the counter electrode substrate is configured such that a first distance between the counter electrode substrate and a part of the transparent conductive oxide in which the dye-adsorbed semiconductor thin film is formed is shorter than a second distance between the counter electrode substrate and a part of the transparent conductive oxide in which the metal grid is formed, and wherein the injection hole is formed in a part of the counter electrode substrate facing the metal grid, a gap is interposed between the protective layer and the short-circuit preventing layer, the dye-absorbed semiconductor thin film comprises parts adjacent to each other across the metal grid, spaces between the parts of the dye-absorbed semiconductor thin film and the counter electrode substrate communicate through the gap, and the electrolytic solution is injected through the short-circuit preventing layer into the spaces and the gap.
