Study of the properties of TiO2 thin films for photovoltaic application

Abstract : TiO2 thin film were deposited on glass substrates, by using sol gel spin coating method with different spin speeds (2900 and 4900) rpm to study their effect on different properties of TiO2 thin films. The structural and optical properties of films have been studied for different speeds. These deposited films have been characterized by various methods such as X-Ray Diffraction (XRD), Ultra Visible Spectroscopy and Raman.The (XRD) can be used to identify the presence of Anatase TiO2 phase in the film deposited. The Raman spectra have been used to confirm the presence of Anatase phase detected by the XRD. The Transmission spectra have shown the transparent and opaque parts in the visible and UV wavelengths. We observed that when the spin speed increases, the optical band gap increases and the opposite is right.
