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...

Organic solar cells (OSCs) based on non-fullerene acceptors have achieved power conversion efficiencies (PCEs) exceeding 20%. However, their long-term stability remains limited by uncontrolled molecular aggregation and morphological degradation in bulk heterojunction (BHJ) films. Here, we report a thiazole-based accept...
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...
