Summary: Rechargeable Zn-air batteries face limitations due to the redox potential of O-2/O2- chemistry in an alkaline electrolyte, resulting in low operating voltages. An asymmetric electrolyte configuration, with a thin and ionically conductive membrane, is proposed to boost the voltage. The use of a Zn ion-exchange membrane and a bifunctional electrocatalyst enables the reversible O-2/O2- reaction in an acidic medium, resulting in an asymmetric Zn-air battery with high energy density and structural stability.

Summary: Dye-sensitized solar cells (DSCs) suffer from reduced power conversion efficiency due to electron recombination with triiodide (I-3(-)) ions at the photoanode/electrolyte interface. Organic additives and inorganic oxide nanoparticles have been explored to reduce recombination and improve efficiency. In this study, aluminum-doped zinc oxide nanoparticles (AZO NPs) were investigated as an inorganic additive with ionic adsorption properties. The addition of AZO NPs significantly decreased recombination, increased open circuit voltage (V-OC) and fill factor (FF) values, and reduced hysteresis. The presence of AZO NPs also resulted in a negative shift in the Fermi level, indicating improved electron lifetime at the TiO2/electrolyte interface. Our findings suggest that AZO NPs have potential as an effective inorganic additive for improving DSC performance.
