Abstract: Using SnCl4 as raw materials and the quantitative filter paper as a template, SnO2 nano-particles were prepared by impregnation and calcination method which were applied in dye-sensitized solar cell. XRD， TEM and SEM were used to characterize the composition and microstructure of the samples. Photoelectric performance and internal impedance of the assembled cells were tested by electrochemical workstation. The results show that high purity and crystallinity nano-sized SnO2 of together-linked structure composited by primary particles of 30 nm are prepared when the concentration of SnCl4 is 1.0 mol/L. The photo-electric efficiency of dye-sensitized solar cell is 1.51% with the best charge transportation property under the same condition.
