本文采用水热法制备了氧化镍纳米丝/多壁碳纳米管（NiO-NF/MWCNT）纳米复合材料，并将其作为染料敏化太阳能电池（DSSC）的对电极。透射电子显微镜、扫描电子显微镜图像和X射线衍射分析清楚地表明了NiO-NF/MWCNT纳米复合材料的形成。采用循环伏安法和交流阻抗法研究了NiO-NF/MWCNT复合电极的电化学性能。特别地，电流-电压测量表明NiO-NF/MWCNT CE的上级功率转换效率（PCE）为7.63%，而铂（Pt）为6.72%。纳米NiO-NF/MWCNT纳米复合材料具有上级光伏性能和低成本，有望作为DSSC的新型对电极。(C)2015爱思唯尔B. V.保留所有权利。
In this paper, we fabricated nickel oxide nanofilament/multiwall carbon nanotubes (NiO-NF/MWCNT) nanocomposite by a simple hydrothermal synthesis method as a counter-electrode (CE) in a dye-sensitized solar cell (DSSC). Transmission electron microscopy, scanning electron microscopy images and X-ray diffraction analysis clearly indicated the formation of NiO-NF/MWCNT nanocomposite. The electro-chemical properties of NiO-NF/MWCNT CE are studied by cyclic voltammetry and electrochemical impedance spectroscopy. In particular, current-voltage measurements indicated superior power conversion efficiency (PCE) of 7.63% of the NiO-NF/MWCNT CE compared to 6.72% for the platinum (Pt). The superior photovoltaic performance and low cost of the NiO-NF/MWCNT nanocomposite can be potentially exploited as a new counter-electrode in DSSCs. (C) 2015 Elsevier B.V. All rights reserved.
