Comment on "Resolving spatial and energetic distributions of trap states in metal halide perovskite solar cells"

Sandheep Ravishankar, Thomas Unold, Thomas Kirchartz

Ni et al. report minimum bulk trap densities of 10^11 cm-3 and 1-4 orders change in interfacial trap densities derived from drive-level capacitance profiling of lead halide perovsk…
