The addition of a block copolymer to the polymer/fullerene blend is a novel approach to the fabrication of organic solar cells. The block copolymer (P3HT-b-P4VP) is used as nanostructuring agent in the active layer. A significant enhancement of the cell efficiency is observed, in correlation with morphology control, both before (as-cast) and after the annealing process.
在聚合物/富勒烯共混物中添加嵌段共聚物是制备有机太阳能电池的一种新方法。嵌段共聚物(P3HT-b-P4VP)用作活性层中的纳米结构剂。观察到电池效率显著提高,与形态控制相关,无论是在(浇铸)之前还是在退火过程之后。
