Organic solar cells (OSCs) hold promise for building-integrated and wearable photovoltaics, yet excessive H-aggregation of non-fullerene acceptors (NFAs) quenches luminescence and lowers the photoluminescence quantum yield (PLQY), limiting further efficiency gains. Here, we introduce NTCl-4F, a molecular H-aggregation...

ABSTRACT All‐polymer solar cells (all‐PSCs) combine the synthetic tunability of non‐fullerene acceptor systems with intrinsic mechanical and thermal robustness of polymer active layers, yet their performance remains limited by pronounced bimolecular recombination, leading to insufficient fill factors (FFs) compared to...

Ordered molecular packing is considered essential for optimizing organic optoelectronic properties. However, despite disordered morphologies with nanoscale phase‐separated structure, bulk heterojunction (BHJ) organic photovoltaics (OPVs) have recently achieved remarkable efficiencies exceeding 20% with Y6‐based non...
Fibrillar networks formed during solution processing play a key role in the high performance of modern organic solar cells (OSCs). Yet their formation is intrinsically non-equilibrium and largely stochastic, leading to discontinuous domains and mismatched donor/acceptor interfaces that limit charge transport. Here, we...
