In order to increase the conversion efficiency of a dye-sensitized porous titanium dioxide solar cell, two conductive substrates are arranged so that the conductive surfaces thereof face each other, at least one of the substrates is a transparent light entry-side substrate, a sintered compact of dye-sensitized porous titanium dioxide is disposed upon the light entry-side substrate, a compact of silicon dioxide particles is disposed upon the substrate facing the light entry-side substrate, and an electrolyte is filled between the sintered compact of dye-sensitized porous titanium dioxide and the compact of silicon dioxide particles. Dye-sensitized porous titanium dioxide solar cells having this configuration exhibit a significantly increased short-circuit current and discharge voltage in comparison to conventional solar cells. |
