Paper Abstract

CuInS2, a promising material for tandem solar cell realization, is doped with Mn, a probing dopant for crystal fields and a creator of fluorescent levels in several crystals. 0.7, 1.2 and 1.9 at % of Mn doped p-CuInS2films were prepared by spray pyrolysis. XRD studies confirmed the chalcopyrite structure with C equals 11.02 and a equals 5.51 A. The direct bandgap obtained from transmission spectra was found to increase with Mn content in the range 1.38 - 1.56 eV. Hall effect studies in the temperature range 190 - 273 K showed a decrease of hole concentration with doping indicating the creation of donor levels by Mn.
