Abstract
Removing the phase impurities (e.g., hexagonal polytypes, PbI<sub>2</sub>) in perovskite films is of vital significance to the improvement of long-term operationally stable solar cells. In <i>Science</i>, You et al. report an effective strategy to convert the PbI<sub>2</sub> photoactive phase into an inactive phase by doping a small amount of rubidium chloride (RbCl) into perovskite precursor solution. As a result, the perovskite solar cells show the efficiency of power conversion as high as 26.1% (certified 25.6%), enhancing operational stability.
