High‐Resolution Multispectral Photovoltaic Imagers from Visible to Short‐Wave Infrared

Advanced Science, EarlyView.
We demonstrate a monolithic quad‐spectral imager that seamlessly integrates visible and short‐wave infrared detection on a single chip. Through direct photopatterning of an all‐polymer bulk heterojunction and colloidal quantum dots, the device achieves high‐resolution (640 × 512) imaging across 350–2400 nm, enabling multispectral capture for ...

Defect‐Engineered MOF/COF S‐Scheme Heterojunction With Dual‐Channel Charge Transport for Ultraefficient Solar‐Powered Heavy Metal Remediation

Advanced Science, EarlyView.
Covalent bond MOF/COF S‐scheme which generated via vacuum‐induced oxygen vacancies are report. OVs at the interface can trigger a dual‐channel charge transport mechanism, significantly enhancing catalytic performance. This work not only designs a high‐performance photocatalysts for environmental remediation, but also induces a new concept of “defect ...

Computation‐Guided Dual‐Site Electrocatalysts for Record‐Performance Nitrite‐to‐Ammonia Conversion

Advanced Science, EarlyView.
Designing Cu doped ZnO catalysts for NO2RR via first principles calculation and boosting electrocatalytic nitrite reduction through Cu‐ZnO synergistic deoxygenation, hydrogenation, and NH3 desorption. Cu doping elevates the d‐band center of Zn, strengthening *NO2 binding and deoxygenation, while ZnO sites regulate water adsorption and dissociation ...

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

Advanced 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 ...
