Nanowire, nanosheet and nanoflower supramolecular assemblies of fullerenes are constructed from self-organization of biphenyl and pyrene substituted PCBM. When 20 wt% PCBPy is blended into P3HT:PCBM as part of the acceptor, devices exhibit the best photovoltaic performance with PCE up to 4.8% by fine tuning of the morphology.
富勒烯的纳米线、纳米片和纳米花超分子组合体是由
联苯和
芘取代的 PCBM 自组织构建而成的。当 20 wt% 的 PCBPy 掺入 P3HT:PCBM 作为受体的一部分时,通过微调形貌,器件表现出最佳的光伏性能,PCE 可高达 4.8%。
