Exciton effects in perovskite nanocrystals

J. Phys. Photonics 2021, 3(2), 021002. doi: 10.1088/2515-7647/abedd0

Abstract

Perovskite nanocrystals (NCs) have garnered interest due to their exceptional properties for optoelectronics. Understanding their charge dynamics is key to device commercialization. Size and morphology, influenced by quantum confinement, play a major role in photo-physical behavior. Recent synthesis advances have enhanced confinement and structural stability, enabling efficient radiative recombination and energy transfer. These materials are promising for tandem photovoltaics and multiple exciton generation. Unique quantum effects observed include the Rashba effect, superfluorescence, polariton lasing, Rydberg exciton condensates, and antibunched photon emission. This perspective reviews these phenomena and the outlook for perovskite NC-based devices.
