AbstractTransparent conducting tin oxide thin films have been prepared by spray pyrolysis technique. Structure, optical and electrical properties of prepared films at different concentration (0.1, 0.2,0.3,0.4) mol/litter were studied at substrate temperature (550ºC) .UV-Vis spectrophotometer shows that the transmittance increases with the decrease in the concentration of SnO2 thin films and it received 87% for the lower concentration (0.1 mol/litter). From AFM image notice that the smoothness and homogeneous of the films are decreasing with increasing the aqueous solution molarity. I-V characteristic of the SnO2 films shows the thin film behavior was close to Ohm’s law.
