In an apparatus for manufacturing a dye-sensitized solar cell, a photosensitization dye solution makes contact with an electrode material layer that functions as a working electrode of a dye-sensitized solar cell so that the photosensitizing dye is adsorbed on the layer. Such an apparatus for manufacturing a dye-sensitized solar cell has a substrate housing section to house a substrate with the electrode material layer formed on its surface, and a circulation mechanism to circulate the photosensitization dye solution in such a way that the solution passes a surface of the substrate housed in the substrate housing section. In such an apparatus, a cross-sectional area of a flow path for the photosensitization dye solution in a portion facing the substrate in the substrate housing section is set smaller than a cross-sectional area of a flow path for the photosensitization dye solution in other portions.

Apparatus for manufacturing dye-sensitized solar cell, and method of manufacturing dye-sensitized solar cell

A dye-sensitized solar cell is provided, wherein it can be produced by a relatively easy and simple process and ensures high conversion efficiency even in cases where the thickness of the porous semiconductor layer is increased. The dye-sensitized solar cellincludes, in the interior of or on the conductive-substrate-side surface of the porous semiconductor layer, conductive metal film, such as a film of tungsten, having a large number of randomly located penetrations. Penetrationsof the conductive metal filmare formed by forming a fine-particle layer on the surface of the porous semiconductor layer, forming a conductive metal film on the surface of the fine-particle layer, and making the fine-particle layer disappear by heating or solvent-cleaning.
