Abstract
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.
