Defect tolerance in Bismuth halide perovskites?

23 December 2019 1 7K Report

Can anyone describe the defect tolerance nature in the bismuth halide perovskites such as A3Bi2X9 and A2AgBiX6. It would be good to have an image explaning defect tolerance nature with the help of orbitals involved in hybridization.

Using dipole cations in constructing perovskite materials helps reducing the deep lying state acting as recombination centers. Such effect is called fault tolerant materials. For more details about this effect please follow the link:
