Abstract:	Nano-porous TiO(2) thin films have been widely used as the working electrodes in dye-sensitized solar cells (DSSCs). In this work, the phase-pure anatase TiO(2) (a-TiO(2)) and rutile TiO(2) (r-TiO(2)) have been prepared using hydrothermal processes. The investigation of photo-to-electron conversion efficiency of DSSCs fabricated from mixed-TiO(2) with a-TiO(2) and r-TiO(2) ratio of 80 : 20 (A8R2) was performed and compared to that from commercial TiO(2) (DP-25). The results showed higher efficiency of DSSC for A8R2 cells with same dependence of cell efficiency on the film thickness for both A8R2 and DP-25 cells. The best efficiency obtained in this work is 5.2% from A8R2 cell with TiO(2) film thickness of 12.0 mu m. The correlation between the TiO(2) films thickness and photoelectron chemical properties of DSSCs fabricated from A8R2 and DP-25 was compared and discussed.
