Abstract

Ag/TiO₂ anodes treated with TiCl₄ were prepared by sol and powder combination technology. Scanning electron microscope (SEM) shows that Ag/TiO₂ film is denser and has fewer gaps after TiCl₄ treatment. X-ray diffraction (XRD) indicates that the TiCl₄ treatment can significantly make the TiO₂ particle size become smaller on the electrode surface. Diffuse reflectance infrared Fourier transform (DRIFT) spectroscopy associated with NH₃ adsorption confirms that the amount of anode surface acidity increase after TiCl₄ treatment. Electrochemical impedance spectroscopy (EIS) measurements show that the R_ct2 corresponding to the TiO₂/dye/electrolyte interface decrease to 3.5 Ω. The TiCl₄ treatment can provide more specific binding sites to the alkaline dyes. Much more dyes can be adsorbed. Therefore, the photoelectric conversion efficiency of dye-sensitized solar cell (DSSC) was improved.
