Advanced Science, EarlyView.This work proposes and constructs the Hefei‐NAMD‐S framework based on machine learning stacked models to investigate the relationship between local polarization and non‐radiative recombination. The results indicate that, compared with A‐site local polarization, B‐site local polarization shows a more evident association with the non‐radiative ...

Ultrafast Hot‐Carrier Cooling in CsPbBr3 Supercrystals via Long‐Range Electronic Coupling
Advanced Science, EarlyView.CsPbBr3 supercrystal self‐assembly, which induces long‐range electronic coupling, enables spatial carrier delocalization that accelerates carrier‐LO phonon scattering and weakens the Auger heating. These effects enable ultrafast, excitation‐intensity‐independent hot‐carrier cooling, offering a trade‐off‐free strategy for high‐performance perovskite ...
