Abstract

A series of nano-scaled Ag/TiO ₂ anode was prepared by photo deposition method with different light time. X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) confirmed that Ag deposited on TiO ₂ surface mainly in zero valent successfully. Electrochemical Impedance Spectroscopy (EIS) measurements showed that the R _ct2 corresponding to the TiO ₂/dye/electrolyte interface decreased 10.4 Ω. Deposition of Ag on TiO ₂ surface can transmit the carriers produced by photo excited dye better than pure TiO ₂. This improved the electrons transmission efficiency of anode. Therefore, the photoelectric conversion efficiency of dye-sensitized solar cell (DSSC) was improved. There is an optimum light time. That is the 10 min measured by experiment.
