摘要

摘要: 经酸化处理的多壁碳纳米管(MWCNTs)与纳米石墨复合后沉积在FTO导电玻璃基底上制备出染料敏华太阳能电池薄膜对电极。利用SEM、TEM、EDS与IR光谱对其进行表征。以MgO掺杂的TiO₂薄膜为光阳极对电池通过循环伏安法(CV曲线)、电化学阻抗谱(EIS)和伏安特性曲线(J-V)进行光电性能分析。结果表明:酸化处理的MWCNTs与纳米石墨复合对电极展现出优异的光催化性能,有利于电池光电性能的提高。电池开路电压及短路电流密度分别可达0.53 V、4.67 mA/cm²,其光电转换效率达到4.10%,与铂对电极的性能相当。

Abstract: A counter-electrode (CE) for dye-sensitized solar cells (DSSCs) was prepared by coating a slurry containing acid-oxidized multi-wall carbon nanotubes and nano-graphite powder onto a fluorine-doped tin oxide conducting glass substrate. The samples were characterized by SEM, TEM, EDS and IR spectroscopy. The CE performance in the DSSCs with MgO-doped TiO₂ as the photoanode was investigated by measurements of current-voltage curves, cyclic voltammetry and electrochemical impedance spectroscopy. Results show that the cell with the CE exhibits the best photoelectric properties of all the carbon-based CEs investigated. The short-circuit current density (J_sc) is 4.67 mA/cm², the open-circuit voltage (V_oc) is 0.53 V and photoelectric conversion efficiency is up to 4.10%, which are comparable with those of the Pt-based CE in DSSCs.
