Abstract: Thin films of Copper Sulphide (CuS) were grown on glass substrates by the Chemical Bath Deposition (CBD) technique at room temperature (300C). Copper Chloride and Thiourea were used as sources for Copper and Sulphur ions respectively. The optical characterization was done by using a UV- VIS spectrophotometer in the wavelength range of 180 nm – 1100 nm. The transmittance of the films was determined directly from the spectrophotometer. Other properties such as absorbance and band gap were calculated. A band gap energy range between 3.00 eV to 3.41 eV was obtained and these results suggest that the films can suitably be used in the fabrication of solar cells.
