Title:
METHOD FOR PREVENTING CATALYST RELEASE FROM DYE-SENSITIZED SOLAR CELL AND FROM CATALYTIC ELECTRODES
Document Type and Number:
WIPO Patent Application WO/2012/014414
Kind Code:
A1
Abstract:
A dye-sensitized solar cell having high durability and heat resistance, in particular, each catalytic electrode, is prevented from releasing a platinum-group catalyst by treating the surface of the catalytic electrode with (a) a sulfur material which has a molecular weight of 32-10,000 and is selected from elemental sulfur, inorganic sulfur compounds containing a sulfur atom having an oxidation number of -2 to 0, and organic sulfur compounds containing a sulfur atom having an oxidation number of -2 to 0, (b) a sulfur material selected from inorganic sulfur compounds that contain no sulfur atoms having an oxidation number of -2 to 0 but contain a sulfur atom having an oxidation number of +1 to +4 and from organic sulfur compounds that contain a sulfur atom having an oxidation number of +1 to +4 [with respect to the sulfur material (b), the surface of the catalyst electrode which has been treated therewith gives an X-ray photoelectron spectrum that has a photoelectron peak in the bond-energy range of 161 to 165 eV], or (c) a mixture of the sulfur materials (a) and (b) and/or by incorporating any of the sulfur materials into the electrolyte layer.
