Understanding the Metal‐Center Mediated Adsorption and Redox Mechanisms in a FeMn(NbTa)2O6 Columbite Material for Anion Exchange Membrane Water Electrolyzers

Advanced Energy Materials, EarlyView.
FeMn(NbTa)2O6‐columbite is a sustainable and high‐performance bifunctional electrocatalyst for anion exchange membrane water electrolyzers, comparable to benchmark catalysts. In situ XAS and DFT analysis show Fe/Mn sites exhibit higher OER activity due to reduced overpotentials and favorable O→OOH energetics. The Nb/Ta sites facilitate charge transfer,

Correlation of Band Bending and Ionic Losses in 1.68 eV Wide Band Gap Perovskite Solar Cells

Advanced Energy Materials, EarlyView.
Piperazinium salt treatments with different anions (chloride, iodide, tosylate, and bistriflimide) influence the energetics, carrier dynamics and long‐term stability of 1.68 eV perovskite solar cells. Chloride treatments achieve the highest efficiency (21.5%) but suffer from fast degradation due to ionic losses.
