Intrinsic photo-degradation and mechanism of polymer solar cells: the crucial role of non-fullerene acceptors
TL;DR: In this article, the effects of non-fullerene acceptors (NFAs) on polymer solar cells (PSCs) long-term stability were investigated, and it was shown that ITIC at the interface of the ZnO/active film is readily decomposed by a photocatalytic reaction; this poor stability arises because the vinyl group of ITIC is chemically more vulnerable than the stable aromatic units in the organic active materials.
