PROBLEM TO BE SOLVED: To provide a photocatalyst film formation method of a dye-sensitized solar cell, which can cause a photosensitized dye to be adsorbed at an intended part with high accuracy and reduce the number of operations.SOLUTION: A photocatalyst film formation method of a dye-sensitized solar cell including a transparent electrode 1, a counter electrode 2, an electrolyte layer 3 arranged between both electrodes and a photocatalyst film 4 which is arranged between both electrodes and on the transparent electrode 1 side and which is formed by adsorption of a photosensitized dye 42 to an oxide semiconductor film 41 comprises: a preparation process of arranging a porous member 5 composed of a porous material on the oxide semiconductor film 41 arranged on the transparent electrode 1 in an adjacent manner or in a contacting manner; and a photosensitized dye adsorption process of impregnating the porous member 5 with a solution of the photosensitized dye 42 and causing the solution of the photosensitized dye 42 to pass through the porous member 5 to supply the solution of the photosensitized dye 42 to the oxide semiconductor film 41 thereby to adsorb the photosensitized dye 42 to the oxide semiconductor film 41. |
