Abstract
Halide perovskites exhibit slow rates of non-radiative electron-hole
recombination upon illumination. Chu et al. [Sci. Adv. 6 7, eaaw7453 (2020)]
use the results of first-principles simulations to argue that this arises from
the nature of the crystal vibrations and leads to a breakdown of
Shockley-Read-Hall theory. We highlight flaws in their methodology and analysis
of carrier capture by point defects in crystalline semiconductors.
