Understanding Light‐Soaking Effects in Silicon Solar Cells by Considering Charge Carrier‐Enhanced Atomic Hydrogen Release

Progress in Photovoltaics: Research and Applications, EarlyView.
We show that many hydrogen‐related effects in silicon solar cells can be explained by direct electron‐assisted acceptor‐hydrogen pair dissociation. Most importantly, it leads to a high concentration of atomic hydrogen, which is highly reactive and diffusive. We provide a unified physical description of LeTID.

Thin Fluoride Insulators for Improved 2D Transistors: From Deposition Methods to Recent Applications

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
2D materials hold significant promise for next‐generation electronic and optoelectronic devices, but suitable gate dielectrics are still a challenge. Fluoride insulators, offering inert, dangling‐bond‐free surfaces, have recently emerged as strong candidates. This review covers recent publications on high‐quality fluoride thin‐film deposition and their

Enhancing Charge Transport and Extraction in Ta3N5 Photoanodes Via Ti Doping and TiN Contact Layers

Small, EarlyView.
Ta3N5${\rm Ta}_3{\rm N}_{5}$ is a promising photoanode for solar water splitting but suffers from poor charge transport and interfacial losses. We combine Ti compensation doping with ultrathin TiN back‐contact interlayers to suppress bulk recombination, enhance carrier mobility and lifetime, and enable efficient carrier extraction, yielding ...

Soft Colloidal Robots: Magnetically Guided Liquid Crystal Torons for Targeted Micro‐Cargo Delivery

Small, EarlyView.
Torons, topological quasiparticles in liquid crystals, can be propelled using electric fields and precisely steered with magnetic alignment, enabling programmable motion without fluid flow. In microfluidic channels, they transport colloidal cargo and exhibit novel dynamic behavior. Their uniformity, softness, and reconfigurability make torons ideal for

Band Gap Tuneability in Antiperovskite‐Based Nitrides AE3PnN and Imides AE5Pn2(NH)2 (AE = Ca, Sr; Pn = As, Sb, Bi)

Angewandte Chemie, Volume 138, Issue 20, 11 May 2026.
A series of imide‐based defect antiperovskites AE5Pn2(NH)2 (AE = Ca, Sr; Pn = As, Sb, Bi) has been synthesized using the ammonothermal method. DFT calculations and spectroscopy revealed direct band gaps suitable for photovoltaic absorber materials. The discovered compounds can further be used as precursors for the synthesis of AE3PnN antiperovskites as

Impact of E× B drift on tungsten impurity transport and analysis of its instantaneous response: a particle Monte Carlo simulation

Nuclear Fusion
Tungsten (W), as the primary plasma-facing material in tokamaks, is incompatible with the core plasma. Even extremely low concentrations of W impurities can contaminate the plasma.
