Title:
DYE-ADSORBED SEMICONDUCTOR ELECTRODE FOR DYE-SENSITIZED SOLAR CELL, DYE-SENSITIZED SOLAR CELL, AND PROCESS FOR PRODUCTION OF DYE-ADSORBED SEMICONDUCTOR ELECTRODE
Document Type and Number:
WIPO Patent Application WO/2011/155131
Kind Code:
A1
Abstract:
Disclosed are: a dye-adsorbed semiconductor electrode which can efficiently utilize light having a wide wavelength range including a long wavelength such as an infrared region wavelength; a dye-sensitized solar cell equipped with the dye-adsorbed semiconductor electrode; and a process for producing the dye-adsorbed semiconductor electrode.
Specifically disclosed is a dye-adsorbed semiconductor electrode for a dye-sensitized solar cell, comprising: a dye which contains at least one component selected from metal complexes of porphyrin, phthalocyanine, naphthalocyanine and a derivative of any one of the aforementioned compounds; and a metal oxide porous semidoncuctor material onto which the dye can be adsorbed. The dye can be adsorbed chemically onto the metal oxide porous semidoncuctor material through the binding of a metal atom in the metal complex to a metal atom in the metal oxide porous semidoncuctor material through an oxygen atom. The metal in the complex and the metal in the metal oxide may be the same as or different from each other.
