摘要
以钼酸、硫氰酸铵和碳纤维(直径0.4mm,长8cm)为原料,采用一步水热法制备了MoS2/碳纤维对电极。利用X射线衍射(XRD)、透射电子显微镜(TEM)、扫描电子显微镜(SEM)及X射线能谱(EDX)对MoS2/碳纤维的微观组织结构进行了表征。采用循环伏安法(CV)对MoS2/碳纤维对电极的催化活性进行了研究。光电性能测试表明,基于MoS2/碳纤维对电极染料敏化太阳能电池(DSSCs)的光电转换效率为3.26%,大于基于Pt/碳纤维电极的光电转换效率2.93%,为低成本DSSC产业化技术研究奠定了基础。
MoS2/carbon fiber counter electrodes were synthesized via a one-step hydrothermal method using molybdic acid,ammonium thiocyanate and carbon fiber as coarse materials.The microstructure of the asprepared samples were characterized by X-ray diffraction（XRD）,transmission electron microscopy（TEM）,field-emission scanning electron microscopy（FE-SEM）and energy dispersive X-ray spectroscopy（EDX）,respectively.The cyclic voltammetry（CV）test results indicated that the electrochemical catalytic activity of MoS2/carbon fiber was superior to that of Pt/carbon fiber.The dye-sensitized solar cells（DSSCs）based on MoS2/carbon fiber exhibited energy conversion efficiency of 3.26%,which was higher than that of Pt/carbon fiber（2.93%）.The experimental results have laid a foundation for industrialization of low-cost DSSCs.
