Abstract :The influence of deposition temperatures on the structural, elemental, optical and electrical properties was investigated. The Rutherford backscattering insert ignore into journalissuearticles values(RBS); and scanning electron microscopy insert ignore into journalissuearticles values(SEM); were used to measure the elemental and morphological properties of the films. The RBS confirms that the stoichiometry was controlled by the deposition temperatures with a thickness that ranged between 51.00 to 63.00 nm. SEM data of the deposited films show different morphologies with several grains that increased with deposition temperature. Optical characterization shows that the films exhibited a direct transition with an energy gap that varies from 1.79 to 2.10 eV. For copper-zinc sulphides insert ignore into journalissuearticles values(CZS); film deposited at 470 ᴼC, the maximum electrical conductivity was 7.38 × 10-2 insert ignore into journalissuearticles values(Ω.cm);-1and minimum electrical resistivity was 1.35 × 101 insert ignore into journalissuearticles values(Ω.cm);. The results confirm the possibility of using copper and zinc dithiocarbamate precursors in depositing high-quality CZS thin films with comparable properties.
