The Effect of Thermo-Vacuum Systems in the Dye Sensitized Solar Cell

Abstract

Dye-Sensitized Solar Cell (DSSC) is currently under the developing progress in worldwide. Usually the laboratories adopt the method for absorbing dyes on film electrodes through placing the specimen sample in the dye for a lengthy soaking (12 hours). Consequently, the study employs the cooperation of thermo-vacuum system on the heating processes. We discovered from the experimental results that the best performance resulted from the heating process, which not only sped up the diffusion velocity of dye molecular being absorbed on the tube but also enhanced the photoelectric efficiency for solar cells, which thereby provided a substantial saving in time for dye soaking and greatly enhanced the economic benefits of products.

The Effect of Sintering and Soaking Temperature on the Dye-Sensitized Solar Cell Performance

“…Sintering is a thermal treatment to form connection of small TiO2 particles into a solid structure. Furthermore, sintering formed a porous TiO2 films which have a large surface area [14] and removed organic compounds that is trapped in the pores of the TiO2. Sintering process was carried out at temperatures, ranging from 400 oC to 500 oC.…”

“…Soaking temperature affected the absorption of the dye on the TiO2 film. The result of Jheng et al's research showed that heating process would not only speed up the diffusion velocity of the dye solution being absorbed but also enhance conversion efficiency [14]. In addition, soaking of the working electrode in the dye solution at 40 -50 oC would open the pores of TiO2.…”
