The study of the inherent charge transport behaviour of 3D lead halide perovskite is challenging, owing to entanglement with ionic migration effects and dipolar disorder instabilities. Here, the authors circumvented both challenges and found that ion migration is much suppressed in mixed metal perovskite compositions relative to pure-Pb counterparts.
