Preparation of Copper-Indium-Sulfide Thin Films by Solution Pyrolysis of Organometallic Sources

Abstract
Thin films of copper-indium-sulfide (CuInS2) were prepared by solution pyrolysis technique using a solution of diisobutylindium propylthiolate-copper bis(dibutyldithiocarbamate) in p-xylene at 250–350 °C. CuInS2 films obtained were characterized by SEM, XRD, and X-ray microanalysis and optical gap of about 1.43 eV was measured.
