【摘要】 采用静电纺丝技术制备碳纳米纤维,通过油浴加热法制备碳纳米纤维负载Re-Pt₃Ni复合材料.为了研究该复合材料对电极的膜厚对染料敏化太阳能电池性能的影响,通过球磨以及喷涂法得到不同膜厚的对电极,分别为5、10、15、20μm,所得电池的能量转换效率分别为5.12%、7.67%、8.43%、8.09%.结果表明复合材料对电极膜厚存在一个最佳值,使电池的能量转换效率达到最高,同时,也表明复合材料有潜力成为Pt电极的替代品.更多还原

【Abstract】 Carbon nanofibers were prepared by electrospinning,then Re-Pt₃Ni Supported by Carbon Nanofibers Composite were prepared by heating in oil bath.The composite electrodes with different film thickness were prepared by ball milling and spraying,and the electrodes were 5,10,15 and 20μm respectively.The influence of film thickness on the performance of dye-sensitized solar cells was studied,Energy conversion efficiency were 5.12%,7.67%,8.43%,8.09%.The results show that with the increase of the thickness of the electrode film,the performance of DSSCs first increases and then decreases,and when the thickness of the electrode is about 15μm,the performance of DSSCs is the best.At the same time,it also shows that the composite has the potential to replace the Pt material.更多还原
