Improved mirrors for applications of concentration of solar energy (CSP) or photovoltaic concentration (CPV), and / or methods of realization thereof

摘要

A method of manufacturing an article, the method comprising: providing a first glass substrate, the first substrate having a thickness of 0.5-3 mm, a low iron content of 0.001-0.06% by weight expressed as Fe2O3 , in terms of percentage by weight of the total glass composition and a low redox value of less than or equal to 0.10 expressed as the ratio of FeO to total iron in terms of percentage by weight; disposing a reflective coating on a main surface of the first substrate; providing a second glass substrate substantially parallel to the first substrate, the second substrate being oriented on the reflective coating, the second substrate being at least as thick as the first substrate; laminate together the first substrate, with the reflective coating disposed on it, and the second substrate, wherein the reflective article has a reflectivity of at least 90 percent, and wherein the second substrate includes a major surface area that is greater than a main surface area of the first substrate.
