METHOD FOR MANUFACTURING THE TIO2 ORGANIC SOLUTION FOR PHOTOELECTRODE OF DYE-SENSITIZED SOLAR CELL AND THE TIO2 ORGANIC SOLUTION MADE THEREBY AND DYE-SENSITIZED SOLAR CELL PRODUCED BY USING THEM

摘要

The present invention relates to a method for manufacturing a titanium dioxide (TiO_2) nano-dispersion solution for a dye-sensitized solar cell photoelectrode, the nano-dispersion solution, and a dye-sensitized solar cell manufactured using the nano-dispersion solution. More particularly, disclosed are the method for manufacturing titanium dioxide nano-dispersion solution for a dye-sensitized solar cell photoelectrode, the nano-dispersion solution manufactured by the same, and the dye-sensitized solar cell using the same, wherein the method comprises: a first mixing process for mixing, in a mixer, a composition including 5-30 parts by weight of titanium dioxide nano-particles, 0.5-10 parts by weight of a dispersing agent, and 60-90 parts by weight of an alcoholic solvent at a speed of 100-200 rpm for at least five hours; a second ultrasonic wave mixing process for carrying out dispersion of the mixture prepared in the first mixing process in an ultrasonic wave dispenser for 30-60 minutes; and a titanium dioxide particle size adjusting process by dispersing the dispersed material formed in the second ultrasonic wave mixing process through a bead mill such that the dispersed particle of the titanium dioxide has a size of 10-150 nm.
