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 ...

Development of a Stable Electrolyte for Dendrite Suppression and High‐Performance Zn–I2 Redox Flow Battery

open access: yesSmall, EarlyView.
An NH4Cl additive stabilizes Zn–I2 redox chemistry in aqueous Zn–I2 redox flow batteries by suppressing iodine precipitation and mitigating zinc dendrite formation. These improve reversibility and electrolyte stability, leading to enhanced coulombic and energy efficiencies, as well as substantially prolonged cycling performance.

Breaking Inversion Symmetry via Vanadium Coordination Engineering in Bismuth Vanadium Selenites

open access: yesSmall, EarlyView.
Vanadium coordination engineering induces symmetry breaking in bismuth selenites by transforming symmetry‐compensated VO6/VO5F units into directionally aligned VO5 polyhedra. The resulting non‐antiparallel vanadyl arrangement eliminates dipole cancellation and stabilizes a polar noncentrosymmetric framework with nonlinear optical activity.
