Enhancing Direct Solar Water Splitting via ALD of Multifunctional TiO2/Pt Nanoparticle Coatings With Engineered Interfaces to GaAs/GaInP Tandem Cells

Advanced Functional Materials, EarlyView.
Multifunctional atomic layer deposited coatings and interface treatments enhance direct solar water splitting on GaAs/GaInP tandem cells. Optimized TiO2/Pt nanoparticle bilayers ensure durability and catalytic efficiency with minimal optical losses, while H2 plasma pretreatments maximize photovoltage and interfacial charge extraction.

Aeroacoustic wind tunnel tests

, 2020
The global demand for renewable energy sources has led to an increase in development and installation of wind turbines. However, noise regulations on wind turbines near populated areas can restrict the installation of new wind turbines and limit the potential energy production. The main noise from wind turbines is aerodynamic and arises from turbulence
