| 摘 要： | 采用静电纺丝技术和水热法合成了负载于碳纳米纤维表面的碳包覆Ni3S4纳米颗粒(Ni3S4@C/CNFs),利用喷涂法制备膜厚分别为2、4、6、7、8、9、10μm的Ni3S4@C/CNFs对电极。应用到染料敏化太阳能电池(DSSCs)中,探究Ni3S4@C/CNFs对电极的膜厚对于DSSCs光伏性能的影响。最终得出当Ni3S4@C/CNFs对电极膜厚为9μm时,DSSCs可以获得最高的光电转换效率(PCE)8.45%,也证明了对电极存在一个最佳膜厚,使DSSCs获得最优的光伏性能。

| Abstract: | Carbon-coated Ni3S4 nanoparticles supported on the surface of carbon nanofibers(Ni3S4@C/CNFs)was synthesized by electrospinning and hydrothermal methods.Then,the Ni3S4@C/CNFs counter electrode with film thickness of 2,4,6,7,8,9,10μm were prepared by spraying method,and applied to dye-sensitized solar cells(DSSCs).The effect of Ni3S4@C/CNFs electrode film thickness on the photovoltaic performance of DSSCs was investigated.If the thickness of the counter electrode was too small,there were not enough catalytically active sites to reduce I3-.However,if the thickness of the counter electrode was too large,the connectivity of the counter electrode film may be deteriorated,and the electron transmission distance may be increased.Therefore,the resistance increased,and the recombination probability of the electron also increased.According to the results,when the Ni3S4@C/CNFs counter electrode film thickness was 9μm,DSSCs achieved the highest photoelectric conversion efficiency(PCE)of 8.45%. |
