A Multifunctional Reducing Molecular Dopant for 16% Efficient Tin Perovskite Solar Cells
Rare Metals, EarlyView.ABSTRACT Although lead‐based photovoltaics have seen remarkable progress, tin‐based perovskite solar cells (Sn‐PSCs) continue to face challenges due to their limited power conversion efficiency and insufficient operational stability. The primary cause of this performance gap is the susceptibility of Sn2+ to oxidation, which promotes rapid defect ...

Rare Metals, EarlyView.ABSTRACT High‐power piezoelectric ceramics which have a wide operating temperature range are essential for sensor and actuator applications in extreme conditions. However, their development is fundamentally hindered by the inherent trade‐off among key parameters (TC, d33, Qm).

Rare Metals, EarlyView.ABSTRACT Photocatalytic hydrogen production from water splitting is a promising strategy for sustainable and clean energy generation. However, the design of low‐cost, highly active photocatalysts remains a critical challenge. In this study, covalent organic frameworks (COFs) were loaded onto the surface of Cd0.9Cu0.1S to fabricate COF/Cd0.9Cu0.1S ...

Rare Metals, EarlyView.ABSTRACT MCrAlX coatings are widely used as bond coats in thermal barrier coating systems to protect turbine blades from high‐temperature oxidation. However, their oxidation resistance is often restricted by uncontrolled microstructures, surface roughness, and aggregation of reactive elements (REs). In this study, high‐repetition‐rate femtosecond laser

Rare Metals, EarlyView.ABSTRACT The growing concern over human health issues, driven by increasingly severe electromagnetic pollution from 5G communication, has made the urgent development of high‐performance electromagnetic wave (EMW) absorbing materials. Although carbide‐based materials are promising because of their conductive and polarization losses, existing single ...
