Influence of Different Solvents on the Formation of Uniform Titanium Dioxide (TiO₂) Thin Film by Sol-Gel

Abstract:

Uniform Titanium dioxide (TiO₂) thin film is essential for application in high performance solar cells. A low cost approach using TiO₂ nanopowder extracted from tin mining waste to deposit TiO₂ thin films is demonstrated in this paper. Furthermore, the influence of different solvents (ethanol, acetone, isopropanol and ethylene glycol) on the formation of uniform TiO₂ thin films in sol-gel technique is studied. The films were characterized by an atomic force microscope (AFM), ultra violet – visible spectrometer (UV-Vis) and a current-voltage (I-V) measurement system. The correlations of the structural, optical and electrical behavior to the type of solvent used were discussed in details.
