A stereoregular β-dicyanodistyrylbenzene (β-DCS)-based conjugated polymer for high-performance organic solar cells with small energy loss and high quantum efficiency

Abstract

We report a new β-dicyanodistyrylbenzene (<bold>β-DCS</bold>)-based polymer (<bold>PBDCS</bold>), which enables efficient fullerene and non-fullerene organic solar cells with low <italic>E</italic>_loss and high EQE.
