GLASS-LIKE POLYMERIC ANTIREFLECTIVE FILMS, METHODS OF MAKING AND LIGHT ABSORBING DEVICES USING SAME

摘要

A transparent anti-reflective structured film(10) comprising a structured film substrate(12) having a structured face(14), with anti-reflective structures, for example, in the form of prismatic riblets(16) defining a structured surface. The structured face is anti-reflective to light, with at least a substantial portion of the structured surface comprising a glass-like surface. At least the anti-reflective structures comprise a cross-linked silicone elastomeric material and the glass-like surface comprises an Si02 stoichiometry. A solar light energy absorbing device is disclosed, comprising the transparent anti- reflective structured film disposed so as to be between a source of light energy and a light energy receiving face of a light absorber, when light energy is being absorbed by the light absorber.
