Shallow defects and variable photoluminescence decay times up to 280 µs in triple-cation perovskites

Nature Materials, Published online: 09 January 2024; doi:10.1038/s41563-023-01771-2

Quantifying recombination in halide perovskites is crucial, but quantitative analysis remains rare. Here the authors observe a long-lived and continuously changing photoluminescence decay time due to the high density of shallow defects and substantial rates of charge carrier trapping.Nature Materials, Published online: 09 January 2024; doi:10.1038/s41563-023-01771-2Quantifying recombination in halide perovskites is crucial, but quantitative analysis remains rare.
