AR Coatings in Solar Efficiency: A Study
Abstract: In the global race toward renewable energy dominance, the focus often fixes upon the exotic materials within the photovoltaic cell: silicon type, junction structure, or emergent perovskites. Yet, the most immediate and profound efficiency gains are often secured by a layer so thin it is invisible, a film of optimized material applied directly to the glass interface: the Anti-Reflective (AR) coating. These coatings are not merely an expensive aesthetic choice; …
