Enhanced dust reduction method for solar panels application

Abstract

Abstract Introducing an innovative dual-layer coating technique to enhance solar panel durability against dust, this method uses a translucent aluminum zinc oxide conductive film to prevent accumulation through active dust repulsion. A secondary TiO2-infused coating, applied via a cost-effective sol-gel method, boosts anti-soiling capabilities in a passive manner. Comprehensive tests on dust accumulation, self-cleaning efficiency, mechanical robustness, UV-VIS transmission, and chemical resilience reveal promising results. These coatings improve glass clarity, reduce dust adhesion, and maintain energy production even in calm conditions. The effectiveness relies on the precise concentrations of aluminum nitrate and Titania nanoparticles, with annealing temperature affecting transmission rates. The coatings demonstrate highly desired resistance to both alkaline and acidic environments, ensuring consistent performance across various settings. This durability supports the widespread adoption of solar energy in diverse climates, advancing global sustainable energy efforts.
