Polarize the Solvent to Regulate the Intermediate Phase and Dynamic Crystallization of Perovskite Films

Advanced Materials, EarlyView.
A solvent engineering strategy using polar polymers is introduced to regulate perovskite crystallization dynamics in solar cells. Strongly polarized fluorinated groups stabilize the intermediate phase and control solvent exfoliation, leading to high‐quality films with suppressed defects.

Superionic Amorphous Li2ZrCl6 and Li2HfCl6

Advanced Materials, EarlyView.
Amorphous Li2HfCl6 and L2ZrCl6 are shown to be promising solid‐state electrolytes with predicted ionic conductivities >20 mS·cm−1. Molecular dynamics simulations with machine‐learning force fields reveal that anion vibrations and flexible MCl6 octahedra soften the Li coordination cage and enhance mobility. Correlation between Li‐ion diffusivity and the
