Abstract

The transformation between black (corner sharing) and yellow (face sharing) polytypes of lead halide perovskites is a major performance bottleneck. We investigate phase intermixing through the simulation of stacking faults (nanodomains) that reveal a small thermodynamic cost but large electronic consequences in CsPbI3.
