In this paper, the fabrication process of photoanode for dye-sensitized solar cells was designed and optimized. Factors which influence the DSSC photoelectric properties were studied under the default manufacturing conditions of the photoanode, respectively, these factors include active area of photoanode, thickness of TiO2 film, adding scattering layer or not, sintering temperature of TiO2 film, chemical treatment method and concentration of TiCl4. The optimum fabrication process for the photoelectrode was determined as follows: the photoanode active layer area was 0.4 cm × 0.4 cm, TiO2 film thickness was 19 μm, and with scattering layer, TiO2 film electrode sintering temperature was T1 = 525oC, secondary sintering temperature was T2 = 500oC, and with 0.1 mol/L TiCl4 aqueous solution for chemical treatment. The experimental results showed that the short circuit current density was 19.45 mA/cm2, and the photoelectric conversion efficiency was 8.42%. This process is beneficial for the structure optimization of DSSC and has a broad application future, due to its simple fabrication process, good spectral characteristics and high photoelectric conversion efficiency.
