Reversible Removal of Intermixed Shallow States by Light Soaking in Multication Mixed Halide Perovskite Films
{{output}}
The highest reported efficiencies of metal halide perovskite (MHP) solar cells are all based on mixed perovskites, such as (FA,MA,Cs)Pb(I1-x Br x )3. Despite demonstrated structural changes induced by light soaking, it is unclear how the charge carrier dynamic... ...
