A PREPARATION METHOD OF ACTIVE ELECTRODE PASTE FOR DYE SENSITIZED SOLAR CELL WITH IMPROVEMENT OF EFFICIENCY BY BINDING METAL NANOPARTICLES

摘要

The present invention relates to a method for manufacturing active electrode paste for dye-sensitized solar cell by adhering metal nanoparticles. More particularly, the method for manufacturing low temperature sintering-capable paste is provided to form -O-Ti-O- networks between titanium dioxide nanoparticles and titanium dioxide precursors, enables coating without fine cracks, to improve the energy conversion efficiency by growing metal nanopaticles in the coating layer by leading an optical reduction reaction after the coating, by dissolving dye into a solvent in advance, dispersing titanium dioxide nanoparticles in the solvent, leading hydrolysis reaction of titanium dioxide nanoparticles with titanium isopropoxide by mixing the titanium isopropoxide which is a titanium dioxide precursor capable of playing a role as a binder in a predetermined mole ratio.
