Synthesis and characterizations of copper cadmium sulphide (CCS) thin films as potential absorber layer for low-cost thin films solar cells has been reported. Thin films of CCS were dip-coated from clear molecular ink consists of copper acetate, cadmium acetate and thiourea dissolved in methanol. Films were heated at 200 °C in air for 15 min. The effect of film thickness on the compositional, morphological, optical and electrical properties were investigated using x-ray diffraction, Raman spectroscopy, scanning electron microscopy, UV–vis spectrophotometer and Hall measurement system. Optical band gap of the films estimated from the Tauc relation was found to be ~2.3 eV. Films are compact and void free having interconnected spherical grains. XRD and Raman spectroscopy confirmed the formation of hexagonal CCS without the formation of any secondary phases. The films are p-type and showed photoconductivity. Temperature variation of electrical conductivity of films measured in the temperature range from 300 to 475 K reveals nearest neighbour hopping (NNH) and thermionic emission (TE) over grain boundary (GB) barriers (GBB) below and above 400 K, respectively. Dip-coated CCS thin films found suitable for the fabrication of thin film solar cells at low cost.
