采用简单的氧化电聚合方法制备了聚（3，4-乙撑二氧噻吩）与功能化多壁碳纳米管（PEDOT-MWCNT）的复合膜。这些膜形成在氟掺杂的氧化锡玻璃基板上作为无铂染料敏化太阳能电池（DSSC）的对电极（CE）。采用扫描电子显微镜（SEM）、原子力显微镜（AFM）、循环伏安（CV）和交流阻抗（AC）等方法研究了PEDOT-MWCNT薄膜的表面形貌、形成机理和电化学性质。SEM和AFM图像显示PEDOT-MWCNT膜比PEDOT膜更多孔。CV和AC阻抗谱表明，PEDOT-MWCNT电极对I3−/I−氧化还原反应具有更高的电催化活性，并且比PEDOT电极具有更小的电荷转移电阻。具有PEDOT-MWCNT CE的DSSC的能量转换效率比使用钌敏化剂的相同条件的PEDOT CE高13.0%。
Composite films of poly(3,4-ethylenedioxythiophene) and functionalized, multi-walled, carbon nanotubes (PEDOT–MWCNT) were fabricated by a simple oxidative electropolymerization method. These films were formed on fluorine-doped, tin oxide, glass substrates as counter electrodes (CEs) of platinum-free, dye-sensitized solar cells (DSSCs). The surface morphology, formation mechanism and electrochemical nature of PEDOT–MWCNT films were investigated using scanning electron microscopy (SEM), atomic force microscopy (AFM), cyclic voltammetry (CV) and alternating current (AC) impedance spectroscopy. The SEM and AFM images showed that PEDOT–MWCNT films were more porous than PEDOT films. CV and AC impedance spectroscopy revealed that the PEDOT–MWCNT electrode had higher electrocatalytic activity for the I3−/I−redox reaction and a smaller charge transfer resistance than the PEDOT electrodes. The energy conversion efficiency of the DSSC with a PEDOT–MWCNT CE was 13.0% higher than with a PEDOT CE using the same conditions with a ruthenium sensitizer.
