Preparation of CuInS2 thin films by metal–organic decomposition Original Research Article

Metal–organic decomposition (MOD) technique has been developed as a low cost thin film CuInS2 preparation method for solar cell application. XRD and Raman spectra measurement revealed that deposited films contain CuInS2. Stoichiometric films with a bandgap of 1.53 eV and an FWHM of 0.45° were obtained from a solution with Cu/In=1.5.
