Abstract

In article number 2003071, Kam Sing Wong and co-workers quantify electron-phonon coupling strength using a simplified two-temperature model in several hybrid lead halide perovskites. Also, the intricate competition of hot-carrier cooling mechanisms between large polaron screening and hot-phonon bottleneck effect are described by unveiling an S-shaped temperature versus carrier density relationship. The findings are expected to help shed light on hot-carrier harvesting in high-performance photovoltaic applications.
