Patent ID: 8748735

Claim:
A process for producing a dye-sensitized solar cell that comprises a transparent substrate, a transparent conductive film formed on the surface of the transparent substrate, a conductive substrate provided opposite to the transparent conductive film, and a dye-adsorbed porous semiconductor layer and an electrolyte between the transparent conductive film and the conductive substrate, comprising the following steps, carried out in the recited order: a first step in which the porous semiconductor layer is formed on the transparent conductive film, on a surface opposite that contacting the transparent substance; a second step in which a fine-particle layer made up of fine particles removable by heating or solvent-cleaning is formed on the porous semiconductor layer, on a surface opposite that contacting the transparent conductive film; a third step in which a conductive metal film is formed on the fine-particle layer on a surface opposite that contacting the porous semiconductor layer; and a fourth step in which the fine-particle layer is made to disappear by heating or solvent-cleaning.
