Patent ID: 8921689

Claim:
A dye-sensitized solar cell comprising: a transparent substrate; a conductive substrate serving as a cathode electrode; a porous semiconductor layer containing a dye adsorbed thereto and arranged between the transparent substrate and the conductive substrate in vicinity to or contact with the transparent substrate; and a conductive metal layer arranged in contact with a side of the porous semiconductor layer opposite to the transparent substrate and serving as an anode electrode, the dye-sensitized solar cell containing an electrolyte sealed therein, wherein the conductive metal layer is formed of a metallic porous body sheet having through-holes, a multitude of the through-holes of the metallic porous body sheet are isotropically communicated with one another, and the metallic porous body sheet has a specific surface area of at least 0.1 m 2 /g, a porosity of at least 30 vol. % and at most 60 vol.%, and a pore diameter of at least 1 μm and at most 40 μm in combination.
