Non-fullerene acceptors have contributed hugely to the best-performing organic solar cells, yet the photo-degradation remains a hurdle preventing the practical application. In this work, research group from Zhejiang University discovers non-fused acceptors with excellent photochemical tolerance in aerobic condition, and identify the main degradation pathway.
