Abstract
The invention relates to a method for preparing nanocrystal ternary titanium dioxide porous electrode by auxiliary crystallization in electrophoretic deposition high-voltage electric field, relating to a method for preparing an electrode and solving the problem that dozens of nano titanium dioxide particles are not beneficial to scattering of light and can not improve the utilization ratio of incident light. The method comprises the following steps of: leading conducting glass coated with mesoporous titanium dioxide and another conducting glass to be in parallel and opposite in non-electrified ternary titanium dioxide size for electrophoretic deposition so as to obtain the titanium dioxide electrode, then leading the titanium dioxide electrode and a conducting basal body to be parallel and opposite for calcining under the condition of applied electric field, thus obtaining the nanocrystal ternary titanium dioxide porous electrode. The space structure of the ternary titanium dioxide layer has high specific surface area same as the titanium dioxide particles, is beneficial to absorbing dye, simultaneously increases scattering of incident light, is beneficial to improving utilizationratio of the incident light and further improves photoelectric conversion efficiency of the battery.
