Particularly conventional systems employing fullerene derivatives are prone to oxidise under illumination, limiting their applicability. Herein, we report on the environmental stability of the small molecule donor DRCN5T together with the fullerene acceptor PC70BM. We find that this system exhibits exceptional device stability, mainly due to almost constant short-circuit current.
