A dye-sensitized solar cell of a duplex structure is provided to form a metal oxide thin film, coated with dye reacting to sunlight, in a two way duplex structure, thereby significantly improving electricity production efficiency per unit area regardless of a location or an angle that sunshine beats down. Two transparent electrode boards(11) are respectively installed in both sides of a solar battery. A counter electrode plate(16) is installed in an inner center closed tightly by the two transparent electrode boards. In the inner side of the transparent electrode board and in both sides of the counter electrode plate, predetermined nano metal oxide layer-photosensitive dye and platinum or carbon coating are respectively formed. A semiconductor oxide film(TiO2)(13) where the photosensitive dye for receiving sunlight and producing electronics is absorbed onto the surface is respectively formed in an inner side of the transparent electrode boards of the sides. In both sides of the counter electrode plate, a platinum or carbon film layer(17) is formed. In a space between the counter electrode plate and the transparent electrode board of the both sides, predetermined electrolyte solution(20) is filled closely. In both sides of the counter electrode plate or in a side contacting the electrolyte layer of the transparent electrode board, a non-conductive projection for preventing direct contact between the counter electrode plate and the transparent electrode board is formed.
