Lett. Status Solidi A, 29. Power-dependent photoluminescence and high injection excess carrier lifetimes at room temperature suggest that degenerate Auger recombination limits the efficiency of our films, although the Auger recombination rates are significantly lower than equivalent III-V bulk materials and even a bit slower than expectations for bulk PbSe.
