Sustainable KCl‐Assisted PbI2 Recycling for High‐Performance Quantum Dot Solar Cells

open access: yesAdvanced Science, EarlyView.
An additive‐assisted lead recycling strategy is developed by introducing trace KCl during PbI2 recrystallization from spent lead‐acid batteries. KCl regulates crystallization and impurity removal, yielding high‐purity PbI2 and enabling the formation of colloidally stable PbS and CsPbI3 quantum dots.

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 ...

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

open access: yesAdvanced 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

open access: yesAdvanced 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

Robust and Tailored 1D/3D Heterojunction for Efficient and Stable Perovskite Solar Cells

open access: yesAdvanced Science, EarlyView.
This study successfully established a robust 1D/3D heterojunction, characterized by a stable 1D phase, favorable lattice matching, strong interface binding, and effective defect passivation. The resulting epitaxial perovskite film demonstrates preferential vertical orientation of (100) facets, thereby facilitating carriers’ transport and stress relief.

Synergistic Pyro‐Phototronics and Structural Anisotropy in CsAg2I3/GaN Heterostructures for High‐Performance Polarization‐Sensitive UV Photodetectors

open access: yesAdvanced Science, EarlyView.
The development of polarization‐sensitive ultraviolet photodetectors is limited by poor heterojunction quality and low polarization sensitivity. This study integrates synthesized CsAg2I3 single crystals with intrinsic non‐centrosymmetry into van der Waals heterojunction devices, demonstrating pronounced pyro‐phototronic effect.
