In the present work, SnO2 thin films were successfully elaborated on a glass substrate by spray pneumatic method with 0.1 M using tin chloride dehydrate at 450 °C by organic solar cells. The effect of deposition rate (5, 10 and 15 ml) on structural, optical and electrical characterizations of SnO2 was investigated. After characterized, we have observed that the elaborated SnO2 thin films have a polycrystalline structure with maximum crystallite size is 35.3 nm for 10 ml. The transmittance of SnO2 thin films were decreased and increased with increasing SnO2 rate in the visible region, it about 60 %, the optical bandgap energy increased with increasing of SnO2 rate from 3.2 eV for 5 ml to 3.6 eV for 15 ml. The electrical conductivity was increased from 0.01 (Ω×cm) –1 for 05 ml of SnO2 to 0.06 (Ω×cm) for 15 ml of SnO2. The prepared SnO2 thin film was suitable for gas sensing applications due to the existing phase and higher electrical conductivity.
