Strategy for One‐Step Optimization of Metal Oxide Passivating Contact Materials for Si Heterojunction Solar Cells through Growth Angle Variation

open access: yesSmall, EarlyView.
A one‐step oblique angle reactive sputtering approach enables simultaneous tuning of bulk and interfacial stoichiometry in a metal oxide/ silicon heterojunction. In case of vanadium oxides, growth angle variation controls the formation of stoichiometric SiO2, ternary SiOx(V) interlayer, and phase purity of vanadium oxide, considerably simplifying the ...

Tuning Optoelectronic Properties and Photoelectrochemical Performance of β‐TaON via Vanadium Doping

open access: yesSmall, EarlyView.
Vanadium‐doped β‐TaON is studied to elucidate how controlled cation substitution modulates crystal and electronic structures and photoelectrochemical performance. Moderate vanadium incorporation (<10 at.%) retains phase purity, narrows the bandgap, and improves charge transport, whereas excessive doping (>10 at.%) induces secondary phases that suppress

Strain‐Modulated Engineering of High‐Entropy Vanadium‐Based Chalcogenide for Sustainable Water Oxidation

open access: yesSmall, EarlyView.
High‐entropy metal chalcogenides (HEMC) incorporating five equimolar transition metals and sulfur were synthesized via an efficient solvothermal method. The resulting HEMC exhibits a single‐phase pyrite (Pa‐3) crystal structure, which was thoroughly characterized using advanced structural analysis techniques. As an anode material, the HEMC demonstrates
