【摘要】 利用化学浴沉积法在FTO基底上制备了厚度可调CuS对电极（CE）。通过X射线衍射（XRD）、扫描电子显微镜（SEM）、紫外-可见（UV-Vis）分光光度计及电化学工作站对CuS对电极的物相结构、微观形貌、光学性质及电化学性能进行了表征。结果表明,在多硫电解液体系中,CuS对电极的电催化活性优于Pt电极;调控沉积周期,可进一步优化CuS对电极表面形貌及电化学性能;CuS对电极最佳沉积周期为6个周期（C）,此时电荷转移电阻达到最小值0.67Ω/cm²,与CdSe胶态量子点敏化TiO₂光阳极组装的电池,能量转换效率可达2.11%。更多还原

【Abstract】 Thickness adjustable CuS counter electrode（ CE） was prepared on FTO substrate by chemical bath deposition method. The crystal structure,morphology,optical property and electrochemical property of Cu S CEs were characterized by X-ray diffraction（ XRD）,scanning electron microscope（ SEM）,ultraviolet-visible（ UV-Vis） spectrophotometer,and electrochemical workstation. The results show that the electrocatalytic activity of Cu S CE is better than that of Pt CE in polysulfide system,and further optimization on morphology and electrocatalytic activity of Cu S CE can be achieved by deposition cycle regulation. The optimal deposition times are 6 cycles（ C）,and value of transfer resistance reduces to the minimum of 0. 67 Ω / cm². Energy conversion efficiency of Cd Se sensitized solar cells based on TiO₂ photoanode and Cu S CE（ 6C） can reach 2. 11%.更多还原
