Paper Title:
Effect of Cu/In Ratio on Properties of CuInS2 Films Prepared by Ultrasonic Spray Pyrolysis Method
  Abstract

CuInS2 thin films were prepared on heated glass substrates by ultrasonic spray pyrolysis method. Structure, surface morphology and properties of films with different Cu/In ratios have been investigated. X-ray diffraction (XRD) analysis demonstrated that as-prepared CuInS2 thin films with chalcopyrite structure have a preferential orientation along the (112) direction. SEM study shows films are relatively dense and smooth, but the much bigger grains and the large coherent agglomerates appear in films (Cu/In>1.25) due to the appearance of phase Cu2S. CuInS2 thin film (Cu/In=1.25) has a strong visible absorption and its energy band gap comes up to 1.45eV.
