METHOD FOR MANUFACTURING THREE-DIMENSIONAL MESOPOROUS TITANIUM DIOXIDE ELECTRODE USING ORGANIC/INORGANIC HYBRID SUPPORT AND DYE-SENSITIZED SOLAR CELL USING SAME

摘要

The present invention relates to a method for manufacturing a titanium dioxide thin film using a polymer-grafted alumina composite as a support and having a mesoporous structure from a titanium precursor. The porous titanium dioxide thin film according to the present invention has a good dye adsorption rate with respect to the high surface area since the porous titanium dioxide thin film has a mesoporous structure and is manufactured by using a polymer-grafted hybrid alumina composite as a support for a sol-gel reaction, and a dye-sensitized solar cell employing the same as a material for a photoelectrode can have high energy conversion efficiency. In addition, the long-term stability of the dye-sensitized solar cell can be improved by using efficient permeation of a liquid electrolyte, a polymer, and a solid electrolyte having high viscosity.
