Transparent superhydrophobic self-cleaning coating increases solar cell efficiency by 4.75%

Researchers have developed a PFAS-free dual-layer sol-gel and hydrophobic silica coating that repels water, dust, and dirt while maintaining high light transmission for solar panels. The transparent, self-cleaning coating improved photovoltaic efficiency from 13.90% to 14.56%, demonstrating strong durability and potential for future commercial applications.An international research team has developed a dual-layer sol-gel and hydrophobic silica coating that can significantly improve solar cell performance by protecting the surface from dust accumulation, light reflection, bird droppings, and water ...
