摘　　要：通过静电纺丝技术和水热法成功获得了碳纳米纤维负载二维层状硫化钼(MoS_2/CNFs),将其作为对电极组装的染料敏化太阳能电池(DSSCs)表现出优异的电化学特性。在DSSCs制备过程中,对电极膜厚对电池性能有很大影响,所以本文重点探究了喷涂法制备的对电极膜厚对其组装的染料敏化电池光电性能影响,获得最佳对电极膜厚。实验结果表明当MoS_2/CNFs复合对电极材料膜厚为8μm时,电池光电转换效率达到最大值7.78%。Two-dimensional layered molybdenum sulfide supported on carbon nanofibers(MoS2/CNFs)were successfully obtained by electro-spinning and hydrothermal methods and showed excellent electrochemical properties.During the preparation of DSSCs,the film thickness of the electrode had a great influence on the performance of the DSSCs.Focuses on the effect of the film thickness of the counter electrode prepared by spraying method on the optical properties of the DSSCs and the optimum counter electrode film thickness was obtained.The experimental results show that the film thickness of the MoS2/CNFs composite counter electrode material was 8μm,the photoelectric conversion efficiency of the battery reached a maximum value of 7.78%.
