英文摘要	A novel architecture of graphene wrapped copper-nickel (Cu-Ni) nanospheres (NSs)/graphene film was proposed to be TCO and Pt-free counter electrode (CE) with high electrocatalytic activity for dye-sensitized solar cells (DSSCs). The novel architecture CE is composed of highly conductive graphene film, Cu-Ni alloy NSs and the wrapping graphene on the surface of alloy NSs. The graphene film as an electrically conductive layer was synthesized by chemical vapor deposition (CVD) on the insulating SiO2 substrate, and graphene wrapped Cu-Ni alloy catalyst NSs on the graphene film were in situ formed by the reduction of Cu-Ni acetate and graphene growth using CVD. The graphene wrapped Cu-Ni NSs/graphene film CE shows much superior electrocatalytic activity, compared with graphene film, and the power conversion efficiency of 5.46% was achieved in DSSC devices, which is close to that of Pt/FTO electrode (6.19%). Therefore, the novel architecture of graphene wrapped Cu-Ni NSs/graphene film CE may be used as Pt- and TCO-free CEs for low-cost, high performance DSSCs. (C) 2015 Elsevier Ltd.
