摘　　要：Unique ZnS nanobuns decorated with reduced graphene oxide （ROO） was synthesized and found to exhibit a synergetic effect as a highly efficient and low-cost counter electrode （CE） in dye-sensitized solar cells （DSCs）. Using this ZnS-ROO CE, a power conversion efficiency （PCE） of 7.03% was achieved. This value was 53% and 41 % higher than those of pure ZnS and ROO CEs, respectively. The ZnS-ROO nanocomposite is indeed an efficient and cost-effective Pt-like alternative for iodine reduction reaction.Unique ZnS nanobuns decorated with reduced graphene oxide （ROO） was synthesized and found to exhibit a synergetic effect as a highly efficient and low-cost counter electrode （CE） in dye-sensitized solar cells （DSCs）.
