Abstract: The aim of this research is to study the role of concentration variations on precursor solution of SnO₂ doped In₂O₃ (In₂O₃:Sn) thin films which has been prepared by spray pyrolysis technique. The change in doping concentration corresponds to changes observed in the XRD spectra, where crystal orientation of In₂O₃:SnO₂ thin films was (211) and (222). All of the In₂O₃:SnO₂ thin films have kept their sharp ultra violet absorption edge, but the transparency in visible spectra region decreases as the molarities in precursor solution increase. These data prove the capability of spray pyrolysis as a viable technique in preparing TCO materials and so, fully transparent CMOS-like devices.
