Popis: The origin of low non-radiative recombination in perovskites was not well-understood. Here, authors apply electric field to manipulate ferroelastic lattice deformation to study non-radiative recombination and strain in twinning tetragonal phase, achieving an increased open-circuit voltage to 1.26 V.
