Overview
An international research team has created a transparent, superhydrophobic dual-layer coating combining sol-gel and hydrophobic silica layers that significantly enhances solar panel efficiency by repelling contaminants without blocking light. This PFAS-free coating improves photovoltaic efficiency by nearly 5%, reduces maintenance costs and risks, and offers strong durability, potentially accelerating the commercial adoption of self-cleaning solar technologies.
