Abstract
A mirror for systems for utilization of solar energy, with a substrate of low absorption flat glass and a rear highly reflective silver reflective layer is provided with a protective layer, a process for its manufacture and its use. In order to render this mirror usable for solar chemical energy utilization as well as to improve the energy yield overall, according to the invention the substrate is provided on its front with a high refractive index dielectric UV reflective layer of a thickness such that it acts as a reflection enhancing interference layer for the near UV region.
