Conformation-Regulated Thiazole Solid Additive for Manipulating Molecular Stacking Behavior Enables over 20% Efficiency in Bilayer Organic Solar Cells
The additive strategy is an effective approach for optimizing morphology of the active layer in organic solar cells (OSCs). To elucidate the impact of distinct molecular conformations of additives on morphology regulation, this work investigates two novel brominated thiazole-based solid additives, namely, 5,5′-dibrom...
