Recombination and localization: Unfolding the pathways behind conductivity losses in Cs2AgBiBr6 thin films

Applied Physics Letters, 2021
Cs2AgBiBr6 (CABB) has been proposed as a promising nontoxic alternative to lead halide perovskites. However, low charge carrier collection efficiencies remain an obstacle for the incorporation of this material in optoelectronic applications. In this work, we study the optoelectronic properties of CABB thin films using steady state and transient ...
