Abstract
Anti-reflective article includes a layer defining an anti-reflective surface. The anti-reflective surface includes a series of alternating micro-peaks and micro-spaces extending along an axis. The surface also includes a series of nano-peaks extending along an axis. The nano-peaks are disposed at least on the micro-spaces and, optionally, the micro-peaks. The article may be disposed on a photovoltaic module or skylight to reduce reflections and resist the collection of dust and dirt.
