Facile and robust strategy to antireflective photo-curing coating through self-wrinkling

A facile and bio-inspired strategy for obtaining antireflective coating is presented through polymerization-induced self-wrinkling with a high transmittance over 90% and low reflection below 5% ∼ 8%, and successful application for an efficiency encapsulation of the thin film solar cells results in appreciable photovoltaic performance improvement of more than 4% ∼ 8%.
