Constructing a dual-fiber network in high efficiency organic solar cells via additive-induced supramolecular interactions with both donor and acceptor

All additives ( TZ-Cl , TZ-2Cl , TZ-3Cl ) can facilitate the formation of a bicontinuous network structure in active layer through supramolecular interactions, and TZ-3Cl achieved PCEs of 19.8% and 20.2% in binary/ternary OSCs.
