Abstract

Read online

Organic solar cells based on solution-processable small molecules still lag behind their macromolecule counterparts. Here, Denget 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.
