While solvent additive engineering is a widely adopted strategy for morphological optimization in organic solar cells (OSCs), conventional high-boiling-point additives often induce excessive molecular aggregation and aggregation-caused quenching (ACQ), which deteriorate electroluminescence quantum efficiency (EQEEL) and exacerbate nonradiative recombination. Herein, we overcome this trade-off by precisely modulating the alkyl chain length of dibromoalkane additives to decouple energetic disorder...
