Mixed‐Polymer Hole Transport Layers Reinforce Au‐Anode Top Emitting Perovskite Light Emitting Diodes

open access: yesAdvanced Science, EarlyView.
Au‐anode corrosion is shown to occur rapidly under voltage bias in MAPbI3 perovskite LEDs. Resulting Au+ migration quickly leads to device shorting and unstable emission during constant current driving. We demonstrate that using a simple mixed‐polymer hole transport layer containing polyTPD and PVK can reduce Au‐corrosion and stabilize LED operation ...

Unconstrained Coordination of Pt Single Atoms on Distorted g‐C3N4 Enables Electronic Flexibility and Enhanced Microplastics Photoreforming

open access: yesAdvanced Science, EarlyView.
This study reveals Pt single atoms anchored on distorted graphitic carbon nitride, exhibiting flexible coordination and enhanced interfacial charge transfer. Combined spectroscopy and DFT reveal asymmetric Pt─N environments that promote photoreforming of microplastics into hydrogen, demonstrating a solar‐driven pathway for plastic upcycling with ...

Furfuryl Alcohol‐Driven Proton Supply Enables Efficient Photocatalytic H2O2 Production Beyond Water‐Based Systems

open access: yesAdvanced Science, EarlyView.
A ZnIn2S4–carbon dot heterojunction enables photocatalytic H2O2 production coupled with furfuryl alcohol oxidation. In this redox system, furfuryl alcohol acts as both the electron donor and oxidation substrate, producing furoic acid with 100% selectivity and 98% conversion while supporting efficient H2O2 generation with a solar‐to‐chemical conversion (

Breaking the Trade‐Off of Mechanical Robustness and Energy Storage Capacity in Phase Change Materials Through a Molecular Design Strategy of Hard‐Segment‐Anchored/Side‐Chain‐Storage

open access: yesAdvanced Science, EarlyView.
To decouple mechanical robustness and energy storage capacity in phase change materials (PCMs), a series of polyurethane‐based PCMs bearing crystallizable alkyl side chains are synthesized via a hard‐segment‐anchored/side‐chain‐storage molecular design.

High‐Performance Multi‐Walled Carbon Nanotubes‐Organic Passivated Si Solar Cells Enabled by Spatially Selective Harvesting of High‐Quality Sponges

open access: yesAdvanced Science, EarlyView.
Our work achieves an efficiency breakthrough in MWCNTs/Si solar cells by screening high‐quality pristine MWCNTs without any separation or purification processes. This breakthrough is mainly attributed to the excellent dispersibility of Nafion and the excellent hole transport property of MWCNTs:Nafion film containing charge transfer doping, passivation,
