Enhanced Exciton Dissociation and Charge Transport Through Fine Morphology Tuning for Efficient Ternary Photovoltaics
kcal/mol) for this blend, indicative of superior thermodynamic stability and favorable formation of a bicontinuous charge transport network. As a result, the devices deliver an outstanding power conversion efficiency of 20.13% (20.01 ± 0.08) together with remarkable operational stability. This study provides a morphology-guided strategy and mechanistic insight for synchronously optimizing exciton and charge management in high-performance ternary OPVs.
