  • A critical factor in the theoretical modelling of nanoscale metal halide perovskites is the system size. Here the authors demonstrate the effect on the band gap of FAPbI3 via octahedra tilting and dipole moments using large-scale ab initio simulations.

  • Substantial open-circuit voltage loss and inherent non-radiative recombination hinder efficiency improvements in wide-bandgap perovskite solar cells. Here the authors augment two-dimensional perovskite phases on the surface to promote (100) facet growth on three-dimensional perovskite facets, improving the open-circuit voltage and efficiency of the resulting wide-bandgap perovskite solar cells.
