摘要

In article number 1601882, Keyou Yan, Jianbin Xu, and co-workers report a simple intermediate halide exchange reaction between nonstoichiometric FAI and unstable intermediate HPbI2Br to produce high-quality FAPbI3-xBrx 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
