Slow Cooling of Hot Polarons in Halide Perovskite Solar Cells

[Image: see text] Halide perovskites show unusual thermalization kinetics for above-bandgap photoexcitation. We explain this as a consequence of excess energy being deposited into discrete large polaron states. The crossover between low-fluence and high-fluence “phonon bottleneck” cooling is due to...
