Electrochemically Deposited Cu-Graphene and Cu2O-Graphene Nanocomposites for Thin Film Photovoltaics

In this study, we present a new approach to electrochemical growth of Cu-graphene and Cu2Ographenenanostructures that are based on simultaneous reduction of copper ions and graphene oxide from anaqueous suspension on Au and indium tin oxide (ITO) electrodes. The obtained composite nanostructures werecharacterized by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), X-ray diffraction(XRD), photoluminescence spectroscopy (PL), and photocurrent measurements. The experimental results showthat structures of Cu-graphene and Cu2O-graphene composite films can be easily controlled by application potentialand experimental media. The resulting Cu-graphene and Cu2O-graphene nanocomposites photoelectrodes exhibitsgood photovoltaic properties and could be used for applications in solar energy conversion.
