METHOD OF FORMING PHOTOCATALYST FILM IN DYE-SENSITIZED SOLAR CELL, DYE-SENSITIZED SOLAR CELL HAVING THE PHOTOCATALYST FILM, AND CONTINUOUSLY MANUFACTURING DEVICE FOR THE DYE-SENSITIZED SOLAR CELL
METHOD OF FORMING PHOTOCATALYST FILM IN DYE-SENSITIZED SOLAR CELL, DYE-SENSITIZED SOLAR CELL HAVING THE PHOTOCATALYST FILM, AND CONTINUOUSLY MANUFACTURING DEVICE FOR THE DYE-SENSITIZED SOLAR CELL
PROBLEM TO BE SOLVED: To provide a method of forming a photocatalyst film in a dye-sensitized solar cell, capable of forming the photocatalyst film in a shorter time and of improving battery performance of the dye-sensitized solar cell, to provide the dye-sensitized solar cell having the photocatalyst film, and to provide a continuously manufacturing device for the dye-sensitized solar cell.SOLUTION: There is provided a method of forming a photocatalyst film 4 in a dye-sensitized solar cell comprising a transparent electrode 1, a counter electrode having a substrate, an electrolyte arranged between these electrodes, and the photocatalyst film 4 arranged between both the electrodes and on the transparent electrode 1 side. The method includes forming a porous film 41A composed of a metal oxide to a dummy substrate D, immersing the porous film 41A in a dye solution 42A to make the porous film 41A adsorb a dye, peeling off the porous film 4A that is made adsorb the dye from the dummy substrate D and melting it in a first solvent S to make the porous film 4A turn into a paste as a dye semiconductor paste 4P, applying this dye semiconductor paste 4P on the transparent electrode 1, and then, baking it.
