Nickel selenide/reduced graphene oxide (NiSe/rGO) nanosheet composite is synthesized by a facile hydrothermal process and used as counter electrode (CE) for dye-sensitized solar cells (DSSC). The NiSe/rGO film spin-coated on FTO show prominent electrocatalytic activity toward I/I. The electrocatalytic ability of NiSe/rGO film is verified by photocurrent-voltage curves, cyclic voltammetry, electrochemical impedance spectroscopy and Tafel polarization curves. On account of its decent electrical conductivity and superior electrocatalytic activity, the DSSC using optimal NiSe/rGO CE achieves a power conversion efficiency (PCE) of 9.75%, while the DSSC based on sputtered Pt CE only obtains a PCE of 8.15%.
镍硒/还原氧化石墨烯（NiSe/rGO）纳米片复合材料通过简便的水热法合成，并用作染料敏化太阳能电池（DSSC）的对电极（CE）。在 FTO 上旋涂的 NiSe/rGO 薄膜对 I/I 表现出显著的电催化活性。通过光电电流-电压曲线、循环伏安法、电化学阻抗谱和 Tafel 极化曲线验证了 NiSe/rGO 薄膜的电催化能力。由于其良好的导电性和优异的电催化活性，使用最佳 NiSe/rGO CE 的 DSSC 实现了 9.75%的功率转换效率（PCE），而基于溅射 Pt CE 的 DSSC 仅获得 8.15%的 PCE。
