Abstract
The influence of substrate temperature on the properties of Cu2ZnSnS4 thin films elaborated by spray ultrasonic method has been investigated. Samples are deposited at various substrate temperature ranged from 280 to 360 °C about 75 min. The results of X-ray diffraction analyses indicated that Cu2ZnSnS4 films have a nanocrystalline structure with (112) preferential orientation and reveals the formation of ZnSnO3 and Cu2ZnSnS4 phases. The crystalline size is varied from 28 to 52 nm with increasing substrate temperature. The optical films characterization was carried out by the measurement of UV-visible transmission. The optical band gap of films deposited at various substrate temperatures is found to lie between 1.40 and 1.6 eV. Electrical conductivity of the films is found to lie in the range 0.9–10 Ω cm−1.
