Harnessing quantum confinement (QC) effects in semiconductors to retard hot carrier cooling (HCC) is an attractive approach for enabling efficient hot carrier extraction to overcome the Shockley–Queisser limit. However, there is a debate about whether halide perovskite nanocrystals (PNCs) can effect...
