Impact of Trap Depth on the Steady‐State and Transient Photoluminescence in Halide Perovskite Films

Advanced Energy Materials, EarlyView.
The presence of shallow traps in halide perovskites is frequently postulated by density functional theory calculations. This review studies the implications of recombination‐active shallow traps on steady‐state and transient recombination kinetics. How to identify shallow traps and how the depth of the traps and their density are reflected in different

Spin Matters: A Multidisciplinary Roadmap to Understanding Spin Effects in Oxygen Evolution Reaction During Water Electrolysis

Advanced Energy Materials, EarlyView.
This roadmap offers a forward‐looking perspective on spin enhancement in the oxygen evolution reaction. It highlights how combining systematic experiments, advanced computational modeling, and novel magnetic, chiral, or hybrid materials can deepen the understanding of spin‐dependent catalytic mechanisms.

Defect Engineering in Semiconductor Photocatalysts: Enhancing Photocatalytic Activity for Green Energy Production

Advanced Energy and Sustainability Research, EarlyView.
By creating anion and cation vacancies, scientists fine‐tune semiconductor bandgaps and extend light absorption, boosting charge separation in photocatalysts. Surface defects enhance reactant adsorption and carrier transport, while controlled bulk defects curb recombination.

Oriented for Efficiency: Textured Se Thin Films Fabricated by Vapor Transport Deposition for Emerging Photovoltaic Applications

Advanced Energy and Sustainability Research, EarlyView.
A low‐temperature vapor transport deposition (VTD) method enables controlled crystallographic texture in Se thin films. Higher annealing temperatures promote vertical (003)‐preferred orientation, enhancing film quality and device efficiency. Optimized morphology and orientation yield solar cells with > 4% efficiency under AM1.5 G and up to 10% under ...

Enhancing Sensitivity across Scales with Highly Sensitive Hall Effect‐Based Auxetic Tactile Sensors

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Herein, a tactile sensor based on hall‐effect sensors with an auxetic structure, called Hall effect‐based auxetic tactile sensor (HEATS), is proposed. The change in magnetism resulting from the deformation of the auxetic structure is utilized for sensing.
