In article number 1906615, Jianjun Tian and co‐workers describe a fully automated spray‐coating technology with ultrathin‐film purification for a commercial large‐scale solution‐based process for colloidal inorganic perovskite CsPbI 3 quantum dot (QD) films. The QD solar cells based on such films show a high power conversion efficiency of 11.2% and can maintain 80% of initial efficiency in air ambient for one month without any encapsulation.
