摘要:
Disclosed is a method for producing a mesoporous titanium dioxide thin film from a titanium precursor by using a polymer-grafted alumina composite as a support. The porous titanium dioxide thin film is obtained by using the polymer-grafted hybrid alumina composite as a support for sol-gel reaction, and thus it has a mesoporous structure and high surface area, thereby providing a high dye adsorption ratio. Therefore, a dye-sensitized solar cell using the mesoporous titanium dioxide thin film as a photoelectrode material has high energy conversion efficiency. In addition, it is possible to improve the long-term stability of a dye-sensitized solar cell through efficient infiltration of high-viscosity polymer and solid electrolyte as well as liquid electrolyte.
