Top and bottom surfaces limit carrier lifetime in lead iodide perovskite films Nature Energy, Published online: 23 January 2017; doi:10.1038/nenergy.2016.207 Understanding surface carrier dynamics enables the design of optimal optoelectronic devices. Yang et al. find that surface recombination limits the total carrier lifetime in polycrystalline lead iodide perovskite films, meaning recombination at surfaces is more important than within and between grains.
