摘　　要：探寻电催化性能优异、廉价的对电极材料是染料敏化太阳能电池发展过程中所面临的重大挑战之一。本文将采用一步溶剂热法合成Ni Se纳米材料,采用喷涂法制备Ni Se薄膜,并作为染料敏化太阳能电池对电极。利用循环伏安曲线、塔菲尔极化曲线、电化学阻抗谱表征对电极的电催化性能。实验结果表明,在I–/I3–体系中,Ni Se对电极展现出了与铂电极相当的电催化性能。通过染料敏化太阳能电池组装与测试,表明基于Ni Se对电极的染料敏化太阳能电池拥有良好的光伏性能,其能量转换效率达到5.27%,与基于铂电极的电池效率（5.34%）相当。Fabrication of low-cost counter electrodes （CEs） with high electrocatalytic performance is one of the most important challenges for the development of dye-sensitized solar cells （DSSC）. NiSe nanomaterials were successfully synthesized by a one-step solvothermal method. NiSe films were fabricated by a spray deposition method, and used as CEs of DSSC. The electrocatalytic activity of CEs were characterized by cyclic voltammetry, curves, Tafel-polarization curves and electrochemical impedance spectroscopy. It is found that the electrocatalytic activity of NiSe CE can be similar to that of platinum （Pt） CE for the reduction of I3-. DSSC was successfully assembled and characterized. The results show that the DSSC based on NiSe CE exhibits high photovoltaic performance. High power conversion efficiency of the DSSC based on NiSe CE is obtained up to 5.27%, which is comparable with that of DSSC based on Pt CE （5.34%）.
