OXIDE OPTICAL SEMICONDUCTOR PASTE FOR SCREEN PRINTING, OXIDE OPTICAL SEMICONDUCTOR POROUS THIN-FILM ELECTRODE AND PHOTOELECTRIC CONVERSION ELEMENT USING IT, AND MANUFACTURING METHOD OF OXIDE OPTICAL SEMICONDUCTOR PASTE FOR SCREEN PRINTING

摘要

PPROBLEM TO BE SOLVED: To provide an oxide optical semiconductor porous thin-film electrode using paste causing very little shear droop in applying it and allowing thick-film printing and automatic printing and having a uniform thickness; and to provide a photoelectric conversion element, a dye-sensitized solar cell, and a dye-sensitized solar cell module including the oxide optical semiconductor porous thin-film electrode. PSOLUTION: An aqueous dispersion with oxide optical semiconductor fine particles dispersed therein is manufactured, then the aqueous dispersion is replaced with a diol-based solvent being an amphiphilic solvent, and thus this oxide optical semiconductor paste with the oxide optical semiconductor fine particles dispersed in the diol-based solvent is manufactured. The paste is applied to a substrate by screen printing and baked to manufacture this oxide optical semiconductor porous thin-film electrode as an optical electrode, and then counter electrode formation and electrolyte injection are executed, whereby this photoelectric conversion element is provided.
