	abstract = {Synthesis and properties of thin copper sulfide films deposited on polyethylene were explored for the development of low cost hybrid org.-inorg. photovoltaic materials.  Polyethylene was used as a model org. host material for thin copper sulfide film formation.  Adsorption-diffusion method was used which utilized consecutive exposure of polyethylene to polythionic acid followed by aq. Cu(II/I) soln.  Several cryst. copper sulfide phases were obtained in synthesized samples and elucidated using X-ray diffraction.  Surface chem. compn. detd. using XPS showed the presence of copper sulfides in combination with copper hydroxide.  Thickness of the composite material films ranged from several microns to \~{}18 μm and depended on the Cu(II/I) exposure time.  Band gap of the materials obtained was measured and ranged from 1.88 to 1.17 eV.  Importantly, heating these complex copper sulfide cryst. phase contg. films at 100 {\textdegree}C in inert atm. invariably resulted in a single copper sulfide, anilite (Cu1.75S), phase.  Anilite possesses a bandgap of 1.36 eV and has demonstrated excellent photovoltaic properties.  Thus, the method described in this work can be used for a low cost large scale composite thin film photovoltaic material deposition based on anilite as photoactive material. [on SciFinder(R)]},
