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

open access: yesAdvanced 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 ...

Ferroelectric‐Polarization‐Driven Structural Engineering of Bi3Nb17O47 Anodes for High‐Performance Lithium‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
A transformative ferroelectric‐polarization strategy is employed to overcome the intrinsic limitations of tungsten bronze (TTB)‐type anode materials in metal‐ion batteries, using Bi3Nb17O47 as a model system. By exploiting the non‐centrosymmetric crystal structure and field‐induced ionic displacements, controlled structural engineering with ...

Cation–Anion Synergy Enables Uniform and Stable SAMs for High‐Efficiency Perovskite/TOPCon Tandem Solar Cells

open access: yesAdvanced Science, EarlyView.
A cation‐anion synergistic strategy is developed to enhance self‐assembled monolayer (SAM) adsorption using guanidinium thiocyanate (GuaSCN). Guanidinium (Gua⁺) suppresses micelle aggregation, while thiocyanate (SCN−) promotes phosphonic acid deprotonation and strengthens ionic bonding to the substrate.

Pt Single‐Atom Activates Surface Lattice Oxygen for Enhanced Acetone Detection Mediated by the MvK Mechanism

open access: yesAdvanced Science, EarlyView.
A Pt single‐atom‐loaded CuO sensing material is developed for acetone detection, demonstrating remarkably enhanced sensing performance. The introduction of Pt single atoms effectively activates the lattice oxygen of the CuO support. A new sensing mechanism based on the Mars‐van Krevelen catalytic mechanism is proposed, offering new insights into the ...

Two‐Dimensional La2CoO4 Perovskite Oxide Enabled by Phonon‐Resonance‐Driven Exfoliation for High‐Performance Gas Sensing

open access: yesAdvanced Science, EarlyView.
Few‐layer La2CoO4 nanosheets are produced via phonon‐resonance‐assisted cleavage of the rock‐salt layers in the Ruddlesden‐Popper structure under the 20 kHz resonance condition, enabling controlled exfoliation into ultrathin sheets. The nanosheets show improved gas‐sensing capability, delivering an 86.67% response to 1 ppm NO2 at room temperature ...
