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 ...

Reinforcement of Cathode Interface Using a Dipolar Small Molecule for Enhancing Operational Stability of Perovskite Solar Cells

open access: yesAdvanced Science, EarlyView.
We report a high‐dipole interlayer, MQPPO, that simultaneously improves efficiency and stability in perovskite solar cells. Its strong interfacial dipole enhances photovoltaic performance, while its uniform coverage and strong interaction with Ag effectively suppress AgI formation, ensuring long‐term stability under moisture and thermal stress.
