PLATINUM CATALYST ELECTRODE AND MANUFACTURING METHOD THEREFOR, AND COLORING MATTER SENSITIZING TYPE SOLAR BATTERY INCORPORATING PLATINUM CATALYST ELECTRODE

摘要

PROBLEM TO BE SOLVED: To provide a platinum catalyst electrode, having superior reduction performance and capable of manufacturing at low costs, and a manufacturing method therefor, and also provide a coloring matter sensitizing type solar battery incorporating the platinum catalyst electrode. SOLUTION: An ink of platinum catalyst precursor is printed on a substrate having conductivity, and then it is changed into a catalyst through heating for obtaining a platinum catalyst electrode.
