Pairing Non‐Fullerene Acceptors With the Right Polymer: Impact of Phase Morphology and Short‐Range Transport on Charge Generation
Organic photovoltaics based on non‐fullerene acceptors (NFAs) have demonstrated high and rapidly increasing power conversion efficiency in recent years. Yet, the requirements for pairing NFAs with an optimal donor polymer remain unclear. To explore the desirable properties of polymers when combining them with NFAs, w...
