Abstract
An object of the present invention is to provide an enlarged dye sensitized solar cell which has a short-circuit preventing structure while a distance between a transparent conductive oxide and a counter electrode, that is, a cell gap is shortened. The dye sensitized solar cell includes 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 film with which the metal grid is coated; a dye-adsorbed semiconductor thin film which is formed on the transparent conductive oxide in which the metal grid is not formed; and a counter electrode substrate, wherein a short-circuit preventing layer is provided in 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.
