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 NH₄⁺ during the perovskite crystallization process to balance the supersaturation discrepancy between AX and BX₂ so as to improve its crystal quality without any residue. Such methodology successfully provides guidance for synthesis route design of highly crystalline perovskites.

钙钛矿结晶：高度结晶钙钛矿的现场管理（Adv。Mater。4/2020）

在1904702号文章中，Zhuo Kang，Yue Zhang和同事提出了A站点管理的概念，即在钙钛矿结晶过程中引入A站点占位阳离子NH ₄ ⁺来平衡AX和BX ₂之间的过饱和差异，因此，以提高其晶体质量，无残留。这种方法学成功地为高结晶钙钛矿的合成路线设计提供了指导。
