Abstract: Reproducible and good quality copper bismuth sulphide (CuBiS₂) thin layer were situated on preheated glassy slide substrates made implementing the spraying pyrolysis approach at distinctive times of spraying 15, 30, 45, and 60 min with a fixed substrate temperature 400°C. The effect of spray time on the structural, morphology, optical and electrical benefits of the CuBiS₂ thin films produced by spray pyrolysis methodology were studied. The structure was studied by XRD methodology. The surface texture of the produced films was considered by SEM. The optical benefits of the CuBiS₂ films were inquired working with the spectrophotometric method in which the optical transmittance and reflectance beyond a wavelength range 200-2500 nm were measured. The d.c. conductivity was studied at different temperatures for all the prepared CuBiS₂ thin films.
