Through analyzing aging performance changes of high humidity stable [(NH 4 ) 2.4 (FA) 8 Pb 9 I 28.4 ] 0.85 (MAPbBr 3 ) 0.15 mixed‐dimensional perovskite, Xu Pan and co‐workers speculate and verify the possible mechanism of its high moisture resistance in article no. 1800276 . After cation exchange of NH 4 + and FA + , NH 4 PbX 3 (H 2 O) 2 and two‐dimensional protective layers are formed on the surface to resist water immersion, and the δ‐phase FAPbI 3 transforms into α‐phase under continuous illumination to maintain the photovoltaic performance.
