Abstract
Polycrystalline copper indium disulphide (CuInS2) thin films were synthesized by a modified spin coating process with spraying the solutions containing precursor materials. Spin-spray deposition was performed at 25 degrees C. The as-deposited CuInS2 thin films were annealed at 400 degrees C for 1 hour under nitrogen atmospheric condition. A scanning electron microscope (SEM) was employed to examine the surface morphology of the polycrystalline CuInS2 thin films. The optical properties were measured using a UV-visible spectrophotometer. Their energy band gap was 2.0 eV. An X-ray diffraction spectrometer (XRD) was used for the structural analysis of CuInS2 thin films. The chemical composition of the CuInS2 thin film was studied with the aid of X-ray photoelectron spectroscope (XPS). The atomic concentrations of copper, indium, and sulfur in the film were determined from energy dispersive spectroscopy (EDS) measurements as a function of the Cu/In ratio in the aqueous precursor solutions.
