The etching processes of glass in aqueous hydrofluoric acid (HF) solutions were used to improve the current density of solar cell. In this study, the textured glass substrate has been etched by solution and the TiO2 thin films have been prepared on this textured glass. After the TiO2 film deposition the surface has been etched by HF under different concentration and the etched TiO2 thin films had a longer electron lifetime and higher haze ratio as well as light scattering, resulting in 1.7 times increment of dye-sensitized solar-cell(DSSC) efficiency. Increases in the surface root-mean-square roughness of glass substrates from 80 nm to 1774 nm enhanced haze ratio in above 300 nm wavelength. In particular, haze ratio of etched TiO2 films on textured glass showed gradually increasing tendency at 550 nm wavelength by increasing of HF concentration up to 10 M, suggesting a formation of crater with various sizes on its surface.
