Halide‐Exchange Arrest Enables Reabsorption‐Free CsPbCl3/CsPbI3 Perovskite Core/Shell Nanocrystals

open access: yesAdvanced Science, EarlyView.
Achieving large Stokes shifts in perovskite nanocrystals is challenging due to halide mobility that disrupts stable core–shell structures. Using CdCl2 passivation, this work stabilizes CsPbCl3/CsPbI3 heterostructures, yielding a ≈1.2 eV Stokes shift, high quantum yield, and fast exciton transfer, enabling reabsorption‐free emitters for advanced ...

Tailoring the Crystallization Behavior of Mixed Lead‐Tin Mixed‐Halide Perovskites for Optimal‐Bandgap Solar Cells

open access: yesAdvanced Science, EarlyView.
Carefully tuning the composition of mixed lead‐tin mixed iodide‐bromide perovskites results in an optimal‐bandgap semiconductor for solar energy conversion. Homogenous crystallization of this perovskite involves a short time delay between deposition of the precursor solution and applying an antisolvent. Using a bulk additive and top surface passivation

Integrated Bulk–Surface Engineering Stabilizes MA‐Free Wide‐Bandgap Perovskites for Tandem Photovoltaics

open access: yesAdvanced Science, EarlyView.
High‐bromide wide‐bandgap perovskites suffer from defects and phase segregation, limiting tandem performance. We report a bulk–surface coupling effect to heal lattice/surface defects and suppress halide migration. As a result, the wide‐bandgap device achieves 23.71% efficiency, while monolithic Si‐based tandems reach 32.26%, exhibiting exceptional long‐

Synergetic Relay Between Atomic Hydrogen and Chlorine Radicals Enables Efficient Nitrate‐to‐Nitrogen Gas Conversion

open access: yesAdvanced Science, EarlyView.
Using photoelectrochemical (PEC) deep denitrification technology, a novel synergistic reduction‐oxidation process enables efficient conversion of nitrate (NO3−) to nitrogen (N2), while suppressing key intermediate ammonium (NH4+) and toxic nitrite (NO2−) accumulation.
