In article number 1904702, Zhuo Kang, Yue Zhang, and co‐workers propose a concept of A‐site management by introducing an A‐site placeholder cation NH 4 + during the perovskite crystallization process to balance the supersaturation discrepancy between AX and BX 2 so as to improve its crystal quality without any residue. Such methodology successfully provides guidance for synthesis route design of highly crystalline perovskites.
