In article number 2001294, Maria A. Loi, Giuseppe Portale, and co‐workers unveil the mechanism of crystallization of Ruddlesden‐Popper Sn‐based perovskites using in situ X‐ray measurements. The addition of a small fraction of the 2D component to the 3D perovskite causes suppression of the bulk crystallization and promotes oriented surface crystallization. Knowledge of the mechanism of crystal formation will help scientists to further optimize the efficiency of lead‐free perovskite solar cells.
