Abstract
One object of the present invention is to provide a transparent electrode substrate with an ITO film formed thereon, used for example as the transparent electrode plate in a dye sensitized solar cell, for which the electrical resistance does not increase even when exposed to high temperatures of 300° C. or higher. In order to achieve the object, the present invention provides a substrate for a transparent electrode, wherein two or more layers of different transparent conductive films are formed on a transparent substrate, and an upper layer transparent conductive film has a higher heat resistance than that of a lower layer transparent conductive film.
