ELECTRODE FOR DYE SENSITIZING TYPE PHOTOELECTROCHEMICAL CELL AND DYE SENSITIZING TYPE PHOTOELECTROCHEMICAL CELL USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a dye sensitizing type photoelectrochemical cell with a little power generation loss and electrode for the dye sensitizing type photoelectrochemical cell with low internal resistance.;SOLUTION: The electrode for the dye sensitizing type photoelectrochemical cell, equipped with a porous body of a semiconductor including dye sensitizing agent and conductive whisker, is provided in the invention. Bipyridine-carboxylic acid-ruthenium (2) complex hydrate is raised as the dye sensitizing agent and substances making titanium oxide main element are raised as the semiconductor. It is preferable for the conductive whisker to be 0.4 to 0.7 m in average diameter, 5 to 20 m in average length, 10 to 20 in aspect ratio and 0.1 to 1 /cm in resistance value. It is preferable for the dye sensitizing agent and the conductive whisker to be within 10 m from interface with solution.;COPYRIGHT: (C)2003,JPO
