Single crystals of CuInS_{2} were successfully grown by chemical vapor transport technique using iodine as transporting agent. The as-grown chemical vapor transport CuInS_{2} single crystals were found to have large resistivity. To decrease the resistivity of the crystals they were doped with three different cadmium concentrations. Seebeck coefficient variation with temperature is measured for all the three doped samples. Optical bandgaps were determined for these three doped samples using optical absorption spectra. The obtained results are discussed in detail.
