Small bandgap porphyrin-based polymer acceptors for non-fullerene organic solar cells†
Abstract
For the first time, small bandgap porphyrin-based polymer acceptors with low-lying frontier energy levels and good crystallinity were developed for application in non-fullerene organic solar cells, in which a broad photoresponse from 300 nm to 1000 nm and an initial PCE of 3.46% have been achieved.
