Abstract

Nanocrystalline CuInSSe thin films were grown on glass substrates using the spray pyrolysis technique. The CuInSSe films were co-deposited from an aqueous solution containing CuCl2, InCl3, thiourea and SeO2. EDC was used as a complexing agent and films were deposited at the constant temperature 300 °C. XRD, Scanning Electron Microscope (SEM) and Energy Dispersive Analysis of X-Ray (EDAX) were used to characterize the samples and the results indicate that the films are single phase, p-type in conductivity and having the chalcopyrite structure. Optical studies show that the optical gap values are 1.23 and 1.39 eV for films grown from spray solutions having S/Se ionic ratios 0.3 and 0.7 respectively. Using the Scherer formula the average crystallite size of the films was found to be in the range 5–11 nm.
