Advancing 1.84 eV Wide-Bandgap Perovskite Photovoltaics Beyond 20% via Single-Facet-Oriented Self-Assembled Molecules.
Uncontrolled crystal growth and structural heterogeneity in solution-processed self-assembled molecules (SAMs) remain major limitations for efficient interfacial charge transport. Herein, we report a dipole-engineered molecular strategy to regulate SAMs crystallization through the rational design of fluorinated benzimi...
