摘　　要：通过静电纺丝和简单的一步水热法合成了碳纳米纤维(CNFs)负载的ZnFe2O4纳米颗粒(ZnFe2O4/CNFs),并将其刮涂在钛网基底上作为染料敏化太阳能电池(DSSCs)的对电极进行组装测试,电池表现出优异的电化学性能。我们着重研究了不同膜厚对电极对DSSCs光电性能的影响。经过反复测试结果表明,当ZnFe2O4/CNFs复合电极材料膜厚为12μm时存在最高的光电转换效率8.60%。ZnFe2O4 nanoparticles supported on carbon nanofibers(ZnFe2O4/CNFs)were synthesized by electrospinning and simple one-step hydrothermal method,and coated on titanium mesh substrate as counter electrode of dyesensitized solar cells(DSSCs),showing excellent electrochemical performance.The effect of different film thickness on the photoelectric properties of DSSCs was studied.The counter electrodes with film thickness of 8,10,12,14 and 16μm were prepared by scraping method.The results showed that the highest photoelectric conversion efficiency of 8.60% was obtained when the film thickness of ZnFe2O4/CNFs composite counter electrode was 12μm.
