Fluorination-enabled optimal morphology leads to over 11% efficiency for inverted small-molecule organic solar cells
Nature Communications, Published online: 19 December 2016; doi:10.1038/ncomms13740
Organic solar cells based on solution-processable small molecules still lag behind their macromolecule counterparts. Here, Deng et al. develop molecular donors to pair with PC71BM and study how the degree of fluorination impacts the morphology of the heterojunction and the efficiency of the devices.
