Large‐Scale In Situ Formation Perovskite Quantum Dots/Elastomer Composite for High‐Performance White Light‐Emitting Diodes

open access: yesAdvanced Science, EarlyView.
A solvent‐free, open‐mill shear protocol nucleates 2.6 nm CsPbBr3 QDs uniformly within brominated butyl rubber. The emitters showed 91% PLQY, 1189 ns lifetime, and > 90% retention after 30‐day ambient storage and water immersion, respectively. Board‐to‐board forms 17 × 17 cm2 flexible films for 132% NTSC white LEDs, scintillators, and stretchable ...

Integrating Cooperative Dual Active Sites Onto a Plasmonic Photocatalyst for Synergistic Promotion of the Reduction and Oxidation Half‐Reactions in Ammonia Synthesis

open access: yesAdvanced Science, EarlyView.
An efficient N2 fixation photocatalyst, Ru‐WO3−x/CoOx, is prepared by integrating respective reduction and oxidation sites onto a plasmonic semiconductor. Owing to optimized reaction kinetics and promoted charge carrier separation by the synergistic effect between the two types of active sites, the involved reduction and oxidation half‐reactions are ...

Decoupling the Transparency‐Efficiency Trade‐Off in Semi‐Transparent Organic Solar Cells via Optimized Dual‐Channel Photoelectric Conversion

open access: yesAdvanced Science, EarlyView.
The respective roles of the heterojunction (HJ) and spontaneously formed photo‐charge (SP) channels in low‐donor‐content devices have been decoupled and subjected to a targeted optimization strategy. A breakthrough of light utilization efficiency (LUE) in semi‐transparent organic solar cells (ST‐OSCs) is achieved.
