Title:
DYE-SENSITIZED SOLAR CELL
Document Type and Number:
WIPO Patent Application WO/2010/150461
Kind Code:
A1
Abstract:
Disclosed is a dye-sensitized solar cell having high power generation efficiency. Specifically disclosed is a dye-sensitized solar cell (10) which comprises a transparent substrate (12), a conductive substrate (14), a porous semiconductor layer (16) that absorbed a dye, and a conductive metal layer (18) that is arranged in contact with a side of the porous semiconductor layer (16) and serves as an anode electrode, said side being the reverse side of a side of the porous semiconductor layer (16) facing the transparent substrate (12). The conductive metal layer (18) is formed from a metal porous body that has through holes, and the plurality of holes of the metal porous body isotropically communicate with each other. The metal porous body has a specific surface area of 0.1 m2/g or more, a void fraction of 30-60% by volume and a void diameter of 1-40 μm, and is formed from a metal material such as Ti, W, Ni, Pt or Au.
