Disentangling Static and Dynamic Contributions to the Urbach Energy in Mixed Sn–Pb Perovskites

Sn–Pb perovskites are promising low-bandgap absorbers for photovoltaics, but their efficiency is limited by the low open-circuit voltage, VOC. The VOC deficit, WOC, is related to energetic disorder, characterized by the Urbach energy, EU, comprising static and dynamic contributions. For Cs0.25FA0.75SnxPb1–xI3, these...
