摘要
采用多种方法对有机聚合物电池的电极进行表面处理,在测量接触角的基础上,应用几何平均法计算了电极样品的表面能和极性度,研究了处理方法对电极表面润湿性能的影响。结果表明,电极表面性能与其处理方法密切相关,等离子处理具有最小的接触角、最大的表面能和极性度,有效增强了电极表面的润湿性能,这一结果对于优化电极/活性层的界面性质,改善有机聚合物太阳电池的光伏性能具有非常重要的作用。
Different treatment methods are used to modify the electrode surfaces of ITO- coated glasses for organic polymer solar cells. Based on the measurements of the contact angles, the surface energy and polarity of the electrodes are calculated by using the geometric mean approach, and the effects of surface treatments on the wettability of the electrodes were investigated. The results demonstrate that the surface wettability of the electrodes is closely related to the treatment methods, and the plasma treatment induces the lowest contact angle, the highest surface energy and polarity, and this will be of great significance for optimizing the properties of the electrode/active-layer interface and improving the photovoltaic performance of organic polymer solar cells.
