Synthesis and Structural Characterization of Thin Films of SnO2 Prepared by Spray Pyrolysis Technique

Thin films of Tin dioxide (SnO2 ) thin films are a special class of metal oxides that combine high electrical conductivity with optical transparency. Such Transparent Conducing Oxide (TCO) provides an important component for optoelectronic applications. Spray pyrolysis deposition for thin film preparation is a simple and relatively cost effective technique. This work consists of the synthesis of thin films of tin dioxide using automated spray pyrolysis technique and its structural characterization. Tin oxide films were prepared from different concentrations of the precursor solution. These films were found to be transparent at low concentration of the precursor solution. Characterization of these prepared films using X-ray diffraction technique is presented and discussed. Spray deposited thin films of tin dioxide have a number of applications, mainly as electrode materials in solar cells.Keywords: Transparent Conducting Oxide, Physical Vapour Deposition, Chemica Vapour Deposition, Transparent Conducting Oxides, Atomic Layer Epitaxy.
