Vacancy-driven stabilization of the cubic perovskite polymorph of CsPbI3

Vacancy-driven stabilization of the cubic perovskite polymorph of CsPbI3

The inorganic halide perovskite CsPbI3 has shown great promise for efficient solar cells, but the instability of its cubic phase remains a major challenge. We present a route for stabilizing the cubic α-phase of CsPbI3 through the control of vacancy defects. Analysis of the ionic chemical potentials...
