Precise Management of n-Value Distribution at the 2D/3D Interface Enabling Efficient Wide-Bandgap Perovskite Solar Cells. [PDF]

Adv Sci (Weinh)
This study elucidates the phase transition pathway of surface‐engineered perovskite films. During spin‐coating, n = 1 2D perovskite dominantly forms, while subsequent annealing drives OA+ release and induces conversion to higher n‐value 2D phases.
