The slow bimolecular recombination that drives three-dimensional lead-halide perovskites’ outstanding photovoltaic performance is conversely a fundamental limitation for electroluminescence. Under electroluminescence working conditions with typical charge densities lower than 1015 cm−3, defect-state...
