We demonstrate an effective nanopatterned anti-reflection coating on glass that is based on solgel chemistry and large-area substrate-conformal soft-imprint technology. The printed 120 nm tall silica nanocilinders with a diameter of 245 nm in a square array with 325 nm pitch, form an effective-index (n = 1.20) anti-reflection coating that reduces the double-sided reflection from a borosilicate glass slide from 7.4% to 0.57% (averaged over the visible spectral range) with a minimum reflectance < 0.05% at 590 nm. The nano-glass coating is made using a simple process involving only spin-coating and an imprint step, without vacuum technology or annealing required. The refractive index of the nano-glass layers can be tailored over a broad range by controlling the geometry (1.002 < n < 1.44 in theory), covering a wide range that is not achievable with natural materials. We demonstrate that the nano-glass coating effectively eliminates glare from smart-phone display windows and significantly improves the efficiency of glass-encapsulated solar cells. These features, that are achieved over an angular range as wide as ±50°, together with strong hydrophobicity and mechanical durability, make nano-glass coatings a promising technology to improve the functionality of optoelectronic devices based on glass encapsulation.
