Strain-activated light-induced halide segregation in mixed-halide perovskite solids

Strain-activated light-induced halide segregation in mixed-halide perovskite solids

Mixed-halide perovskites are of interest for photovoltaic devices, but light-induced halide segregation obstructs bandgap tuning and is not fully understood. Here the authors study the effects of strain and iodide/bromide ratio on light-induced halide segregation in mixed-halide perovskites.
