Can morphology tailoring based on functionalized fullerene nanostructures improve the performance of organic solar cells?

[摘要]：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.
