NOVELTY - The dye-sensitized solar cell has photoelectrode (8), counter electrode (9), and electric-charge carrying layer (4). The photoelectrode has photoelectric-conversion layer (3) formed on electroconductive base material (2). A reverse-current protection layer (2-1) is provided between the base material and layer (3). Layer (2-1) is formed using peroxide titanic acid aqueous solution and/or peroxo modified anatase-sol liquid.    USE - As dye-sensitized solar cell.    ADVANTAGE - The dye-sensitized solar cell has excellent photoelectric-conversion efficiency. The reverse-current protection layer is formed easily at low temperature without carrying out strict control of humidity, with sufficient adhesive strength and thickness control. Since the protection layer is formed at a low temperature, the use of plastic electroconductive base material having low heat resistance is enabled.    DETAILED DESCRIPTION - The dye-sensitized solar cell has a photoelectrode (8), a counter electrode (9) facing the photoelectrode, and an electric-charge carrying layer (4) held between the photoelectrode and the counter electrode. The photoelectrode has a photoelectric-conversion layer (3) consisting of a semiconductor, formed on an electroconductive base material (2). A dye is adsorbed on the semiconductor. A reverse-current protection layer (2-1) is provided between the electroconductive base material and the photoelectric-conversion layer. The protection layer is formed as a titania film on the surface of the electroconductive base material, using peroxide titanic acid aqueous solution and/or peroxo modified anatase-sol liquid as a titania precursor-containing liquid.    An INDEPENDENT CLAIM is included for manufacture of dye-sensitized solar cell.
