Recent advances and prospects of asymmetric non-fullerene small molecule acceptors for polymer solar cells
Liu Ye,Weiyu Ye,Shiming Zhang +2 more
TL;DR: In this article, the authors summarized the latest developments in asymmetric small molecule acceptors (A-NF-SMAs) with the acceptor-donor-acceptor (A−D−A) and/or acceptor−donor−acceptor-non-fullerene (N−A−N−N) structures, and explored the advantages of asymmetric SMAs from the aspects of charge transport, molecular energy level and active layer accumulation morphology.
