TiO2 thin film deposition by chemical methods

Mesoporous nanocrystalline TiO2 dye sensitized solar cells was obtained by the sol-gel process in an aqueous solution using the titanium diethanolamine complex as the precursor and the spin coating technique to obtain TiO2 films on ITO (Indium tin oxide) glass substrates. TG – DTA, BET, FT-IR, UV – VIS, SEM, Raman spectroscopy, X-ray diffraction techniques, have been used to investigate the chemical and physical changes during the sol - gel process and the characteristics of the TiO2 powder precursor.
