Title: Electrodeposition and characterization of CuInSe2/CdS multilayered thin films deposited on flexible substrate

Abstract: Highly efficient multilayered thin films of Kapton/Ni/CIS/CdS/AI were obtained. Kapton is a plastic material with good flexibility, mechanical and high temperature resistance. A 1.5 micron layer of nickel was deposited on kapton material by TVA method. Single step co-deposition method was used to prepare the CIS layer. A subsequent 350 degrees C annealing was applied to improve CIS crystallinity and homogeneity. A CdS layer was deposited by single source thermal vacuum evaporation method. XRD and SEM-EDAX analyses confirmed a uniform and near to CIS stoichiometry composition. Ellipsometry revealed band gaps of 1.03 eV for CIS and 2.46eV for CdS, which confirm the literature data.
