NOVELTY - The dye-sensitized solar cell (10) has a non-electroconductive separator (16) which forms a chamber surrounding a photovoltaic layer (14) and a porous titanium layer (15) arranged between a front side transparent substrate (11) and a back side substrate (13). A titanium electrode (17) is electrically connected to the porous titanium layer and extended to the exterior of the separator. An iodine solution (18) is provided to fill the space formed by the separator and the substrates.    USE - Dye-sensitized solar cell.    ADVANTAGE - The need to provide a transparent electrode in the front side transparent substrate is avoided, by forming the porous titanium layer in the inside of the solar cell. Since the porous titanium layer has small electrical resistance than that of the transparent electrode, the increase of internal resistance of the solar cell can be suppressed while enlarging the solar cell or the area of the front side transparent substrate. The durability of the dye-sensitized solar cell can be stabilized. The increase of distance of the inner side of the front side transparent substrate and an electrically conductive film of the back side substrate can be suppressed, so that electric power generation performance of the solar cell can be improved. The electrical connection of the titanium electrode with the porous titanium layer can be reliably performed. The formation of the titanium electrode and porous titanium layer can be simultaneously performed. Hence the manufacturing process of the solar cell can be simplified.
