Patent ID: 8835755

Claim:
A laminated film comprising a porous semiconductor layer, a transparent conductive layer and a transparent plastic film, wherein the porous semiconductor layer comprises crystalline titanium oxide fibers having a fiber diameter of 50 to 1,000 nm and a fiber length/fiber diameter ratio of 5 or more and being in a non-woven state in an amount of 10 wt % or more and crystalline titanium oxide fine particles having a particle diameter of 2 to 46 nm in an amount of 15 wt % or more, the crystalline titanium oxide fibers and the crystalline titanium oxide fine particles are substantially composed of an anatase phase and a rutile phase, the anatase phase content ratio calculated from the integral intensity ratio of X-ray diffraction is between 1.00 and 0.32, and the laminated film is used in an electrode for dye-sensitized solar cells.
