采用循环伏安法（CV）在室温下在掺氟氧化锡（FTO）玻璃基底上成功生长了厚度可控的纳米结构聚苯胺薄膜。通过循环伏安法、交流阻抗谱、扫描电子显微镜和原子力显微镜对聚苯胺膜的形成机理进行了研究。发现纳米结构聚苯胺（>70nm）在分散层和致密层上的积累同时增加了反应界面，这支持了界面处的电荷转移和阻碍膜中电子输运的电阻。通过优化制备条件，与电沉积铂CE的染料敏化太阳能电池（DSSC）相比，具有PANI对电极（CE）的染料敏化太阳能电池（DSSC）的短路光电流密度增加了11.6%。
Nanostructured polyaniline films with controlled thickness have been successfully grown on fluorine-doped tin oxide (FTO) glass substrates using the cyclic voltammetry (CV) method at room temperature. The formation mechanism of the polyaniline film is monitored by CV techniques, alternating current (AC) impedance spectroscopy, scanning electron microscopy (SEM) and atomic force microscopy (AFM). It is found that the accumulation of nanostructured polyaniline (>70nm) on both the scattered and compact layers simultaneously increased the reactive interface, which supports charge transfer at the interface and resistance that hinders electronic transport in the film. By optimising the preparation conditions, the short-circuit photocurrent density of a dye-sensitised solar cell (DSSC) with a PANI counter electrode (CE) increased by 11.6% in comparison to a DSSC with an electrodeposited platinum CE.
