Abstract
Highly conductive and transparent indium-doped zinc oxide thin films were deposited by the chemical spray technique on sodocalcic glass substrates starting from zinc acetylacetonate. The role of the type of alcohols, namely, methanol, ethanol and isopropyl and the substrate temperature on the electrical, structural, surface morphology and optical characteristics of the thin films were studied. The results show that some of the physical characteristics under study are effectively modified by the temperature as well as the kind of the alcohol used. A resistivity value of 3 × 10-3Ωcm with a mobility of 6cm2/(Vs) and a carrier concentration of 10 21cm-3 were found for the best films. All the films were polycrystalline fitting well with a hexagonal wurtzite structure. High texture surface, which enhance light trapping was observed in films deposited with an ethanol-containing solution. The transmittance of the films is higher than 85% in all the cases, and a band gap value of around 3.3eV was also found.
