Herein, we propose a new approach of molecule occupancy via a vapor treatment to facilitate the conversion of PbI2 to perovskite in sequential deposition. We have shown that the morphology of PbI2 and the subsequent crystallization of perovskite can be effectively tuned, thus leading to the elimination of residual PbI2 and promotion of perovskite growth.

通过正丁胺处理可促进分子在顺序沉积中的转化，从而将PbI2转化为钙钛矿。

在本文中，我们提出了一种通过气相处理促进分子占据的新方法，以促进PbI2在顺序沉积中转化为钙钛矿。我们已经表明，PbI2的形态和钙钛矿的后续结晶可以有效地调整，从而导致消除残留的PbI2和促进钙钛矿的生长。
