Abstract Phase‐pure crystallised perovskite is considered an excellent precursor for fabricating high‐stability films with minimal defects. However, currently available protocols synthesising perovskites must be conducted in inert atmosphere or the presence of organic solvent as reaction medium, which hinders mass production.
