Decoding Trap States in Working 2D Perovskite Multi‐Functional Devices

open access: yesAdvanced Science, EarlyView.
Illustration of the photoluminescence spectrum and energy‐level landscape governing trap‐mediated carrier dynamics in 2D F‐PEAI photodetectors. A novel approach capturing dynamic trap occupation and retrapping in devices under operating conditions, directly links defect energetics to carrier transport and enhanced photoresponse in multifunctional ...

Precision‐Engineered Silver Single‐Atom Carbon Dot Nanozymes for Theranostic Management of Acute Kidney Injury

open access: yesAdvanced Science, EarlyView.
Mitochondria‐targeted silver single‐atom carbon dot (T‐AgSA‐CDs) nanozymes enable dual SOD/GPx‐like ROS scavenging, real‐time imaging, and therapeutic effects for acute kidney injury (AKI). Atomically dispersed Ag sites synergize with carbon dots to restore renal redox hemostasis, protect mitochondrial function, mitigate inflammation, facilitate post ...

Defect Dynamics and Solution‐Processed Interconnects in Perovskite‐Organic Tandem Solar Cells

open access: yesAdvanced Science, EarlyView.
In this study, we identify the underlying cause of efficiency losses in WBG perovskites, which is ascribed to the presence of mobile defects distributed at surface regions. We further employ effective passivation agent with functional chemical groups to facilitate the healing of the mobile defects, thereby enhancing the VOC to 1.35 V and champion ...

3D‐Printed Architected Anisotropic Channels for Ultrafast Solar‐Driven Interfacial Evaporation via Localized Thermal Management and Water Layer Structuring

open access: yesAdvanced Science, EarlyView.
A 3D‐printed anisotropic channel evaporator integrates directional geometry with aligned titanium oxide, boron nitride, and chitosan networks to coordinate photon absorption, heat localization, and water transport. Phonon‐guided thermal pathways and interfacial water structuring enable ultrahigh evaporation rates and long‐term salt‐resistant solar ...

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 ...

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‐

Dual‐Responsive Yarn‐Based Artificial Muscles for Adaptive Thermal Management

open access: yesAdvanced Science, EarlyView.
Inspired by the conscious movements of skeletal muscle, a novel hybrid yarn‐based artificial muscle (HYAM) coupling moisture actuation with controllable recovery is developed. This unique design increases actuation stroke by 128% and shortens recovery time by 91%. This unique design enhances the actuation stroke by 128% and reduces the recovery time by
