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

Advanced 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 ...

Site‐Specific Carboxylate Functionalization in Conjugated Hole Transport Polymers Enables Efficient CsPbI2Br Single‐Junction and Tandem Solar Cells

Advanced Science, EarlyView.
Two polymeric isomers, 2TC‐F and TTC‐F, are designed and synthesized as hole transport materials to investigate the impact of the carboxylate side‐chain connection site. The TTC‐F isomer, owing to its superior energy level alignment, higher planarity, and more effective defect passivation, enabled CsPbI2Br single‐junction and CsPbI2Br/D18:Y6 tandem ...

Extending Carrier Diffusion via Interfacial Dielectric Shielding for Operationally Stable Perovskite/TOPCon Tandem Solar Cells

Advanced Science, EarlyView.
A high‐dielectric niobium oxide (NbOX) electron‐selective contact is introduced to modulate the perovskite/C60 interface in perovskite/silicon tandem solar cells. By shrinking the defect capture radius and chemically passivating Pb‐related defects, NbOX extends carrier diffusion length and optimizes energy‐level alignment, enabling both high efficiency
