Polymer/copper indium sulfide (CIS) nanocomposite solar cells are prepared via a capper free in situ preparation route using copper and indium xanthates as precursors, which decompose and form CIS nanoparticles in the polymer matrix during a mild thermal treatment. The solar cells generate current in a wide range of the solar spectrum and exhibit efficiencies up to 2.8%.
