In situ mapping of iron oxidation in laminar metal fuel flames using X‐ray absorption spectroscopy

Journal of Synchrotron Radiation, EarlyView.
For the first time an iron metal flame has been mapped by in situ X‐ray absorption spectroscopy. Strong gradients in oxidation state and phase composition across the metallic core and the flame front were found with FeO peaking at the visible flame front and Fe3O4 forming further beyond.Metal fuels such as iron are promising carbon‐free energy carriers

Vapor‐Phase Grain‐Boundary Anchoring Enables Molecular Toughening and Record Bending Endurance in Pilot‐Scale Roll‐to‐Roll‐Printed Flexible Perovskite Modules

Angewandte Chemie, Volume 138, Issue 30, 20 July 2026.
A vapor‐phase molecular toughening strategy is developed for pilot‐scale roll‐to‐roll (R2R) ‐compatible fabrication of flexible perovskite solar modules. Thiol vapor selectively regulates crystallization and anchors at grain boundaries, reducing defects while enhancing mechanical resilience.

Review of Amorphous Gallium Oxide: From Material Synthesis to Device Applications

physica status solidi (a), Volume 223, Issue 15, 5 August 2026.
Amorphous gallium oxide (a‐Ga2O3) is reviewed as a promising ultra‐wide‐bandgap material for solar‐blind UV photodetectors. The influence of structural disorder, defect states, and trap‐assisted transport on optical and electronic performance is examined.

Composition pinning growth for efficient and stable all‐inorganic Pb‐Sn perovskite solar cells

InfoMat, Volume 8, Issue 8, August 2026.
All‐inorganic Pb‐Sn perovskite solar cells are promising for low‐bandgap photovoltaics, but uneven Pb/Sn composition during film growth can create defects and reduce performance. In this study, composition pinning growth was used to hold the Pb/Sn ratio steady during CsPb0.5Sn0.5I3 crystallization, producing more uniform films and higher‐performing ...

Simulation Insights Into Enhanced Emitter Contact Passivation via LECO on Industrial TOPCon Solar Cells

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 8, Page 1010-1022, August 2026.
Numerical simulations were employed to boost industrial TOPCon cells from 25.5% to 26.07% by suppressing J0e,metal,eff without compromising ρc with a dual optimization strategy: (1) engineering the selective emitter sheet resistance (Rsh_SE) to 117 Ω/□ and (2) reducing the LECO‐induced partial metal contact ratio (fpmc) to 1%.
