Synergistic Modulation of Intermolecular Interactions and Energetic Disorder Enables 20.05% Efficient Binary Organic Solar Cells.
Simultaneously optimizing active layer morphology and suppressing energetic disorder is still a key obstacle to developing high-efficiency non-fullerene organic solar cells (OSCs). To overcome this limitation, we introduce a novel highly electronegative small molecule material containing a pyridyl group, 2,6-dichloro-4...
