The TiO<sub>2 </sub>films on glass substrates successfully obtained by spin-coating process using TiO<sub>2 </sub>nanopowder as precursor. Ultraviolet-Visible (UV-Vis), Scanning Electron Microscopy (SEM) equipped with Electron Diffraction X-ray (EDX) and X-ray Diffractometer (XRD) techniques used to characterize the films. The result of electron transport material (TiO<sub>2</sub>) showed that film prepared from 15 wt % of TiO<sub>2</sub> solution and annealed at 450 &nbsp;has highest transmittance at visible light region with indirect optical band gap of 3.24 eV which corresponds to wavelength of 382 nm whereas 20 wt % has indirect band gap of 2.99 nm equivalent to 414.7 nm . The chemical analysis from Electron Diffraction Spectroscopy (EDS) of the material shows titanium and oxygen present at L and K-shells, respectively. The sample crystallized with preferred orientation at (101) from XRD analysis.</p> 2020-03-05T11:25:09+00:00 ##submission.copyrightStatement##
