Self‐Adaptive Anhydrous Passivation Mitigates Open‐Circuit Voltage Loss in Pb‐Sn Mixed Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
In this report, a self‐adaptive anhydrous passivation strategy is introduced by incorporating trimellitic anhydride (TMAH) into the perovskite precursor. In situ hydrolysis of TMAH yields trimellitic acid (TMA); ‐C═O/‐COO− groups of TMAH/TMA form a chelate with undercoordinated Pb2+/Sn2+, regulate nucleation, promote (100) orientation, passivate ...

A Bilayered Inorganic‐Metal Interface Enables Highly Reversible Aluminum Deposition for Long‐Life Aqueous Batteries

Advanced Functional Materials, EarlyView.
A gradient M/MOx (M = Sn, Cu, Cd) synergistic interphase was constructed on Al via a one‐step displacement reaction. This interphase leverages high aluminophilicity and ion‐buffering capability to accelerate desolvation, enhance Al3+ transport, and suppress side reactions, enabling ultrastable symmetric cell operation at 0.05 mA cm−2 for 1800 h with an

Chiral Phase Change Nanomaterials

Advanced Functional Materials, EarlyView.
This work demonstrates reversible, non‐volatile phase transitions in chiral Ge2${\rm Ge}_2$Sb2${\rm Sb}_2$Te5${\rm Te}_5$ (GST) nanohelices for high‐speed optical modulation of chirality and dynamic control of the state of polarization (SOP). The chiral nanostructures are fabricated using a highly directional, wafer‐scale physical vapor deposition ...
