Paper Title:
An Investigation of TiO2 Thin Film in Dye Sesitized Solar Cells by Electrophoresis Method
  Abstract

This research adopts modified Submerged Arc Nanoparticle Synthesis System to produce TiO2 nanoparticle which has good roundness and consistence in size. The TiO2 nanoparticle produced is coated on conductive glass by electrophoresis, and then combined with dyes, electrolyte (I-/I3 -), carbon film and conductive glass to produce dye sensitized solar cells; its electro-optical conversion efficiency is measured. As the results of experiment show, the average roundness of those TiO2 nanoparticle is 1.29 nm and their average diameter is 26.5 nm. In the process electric current, electric voltage, and time to finish the film are controlled to obtain TiO2 film with thickness of 0.5~1.3μm . To make TiO2 nanofilm by electrophoresis has the advantages of high flatness and high roughness, and can increase the effects of dye coating. In addition, the dye sensitized solar cells produced are exposed to Metal Halide Lamp, and their electro-optical conversion efficiency is measured. The results show that the electro-optical conversion efficiency is higher than commercial ones.
