Hot Carrier Mobility Dynamics Unravel Competing Sub-ps Cooling Processes in Lead Halide Perovskites

Jacques-Edouard Moser, Andrés Burgos Caminal, Arun Aby Paraecattil, Juan Manuel Moreno Naranjo, Aurélien René Willauer

The outstanding photovoltaic performances of lead halide perovskite (LHP) thin film solar cells are due in particular to the large diffusion length of photocarriers. The mechanism behind this property and its dependence on the various anions and cations in ...
