Abstract
An improved transparent laminar structure useful as a window in a solar collector having an absorber characterized with a low absorption/emission ratio is described. The structure includes a glass substrate, a particularly defined infrared-reflecting (IRR) layer provided on a major surface of the substrate, and a solar reflection-reducing layer of polymethacrylate composition provided on the IRR layer. Also described are an improved solar collector and method for collecting solar radiation, wherein the laminar structure is employed.
