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...

Sequential deposition (SD) process has emerged as a key method for precisely controlling the active layer morphology, which is crucial for enhancing the photovoltaic performance of organic solar cells (OSCs). However, conventional SD methods often face challenges such as interfacial erosion and disordered crystallizati...

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...
