In article number 1601882 , Keyou Yan, Jianbin Xu, and co‐workers report a simple intermediate halide exchange reaction between nonstoichiometric FAI and unstable intermediate HPbI 2 Br to produce high‐quality FAPbI 3‐ x Br x thin films with crystal domain up to 2‐3 μm, eliminating the use of antisolvent dripping process. And it demonstrates outstanding opto‐electronic performances as well as enhanced stability under moisture and heat stress.
