Abstract:
1. A method of making a mirror for use in a concentrating solar power apparatus, the method comprising: bending a thick glass substrate having a thickness of at least 2.0 mm into a desired bent shape so as to form a pre-bent thick glass substrate; forming a mirror coating on a relatively thin glass substrate having a thickness of from about 1.0 to 2.0 mm, the mirror coating being formed on the thin glass substrate when the thin glass substrate is in a substantially flat shape, the thin glass substrate having a thickness less than the thick glass substrate; after the mirror coating has been formed on the thin glass substrate, laminating the thin glass substrate to the pre-bent thick glass substrate using at least one polymer inclusive adhesive layer to form a laminate mirror comprising a substantially parabolic shape, wherein the laminate mirror is used in a concentrating solar power apparatus and has a solar reflectance of at least 90%.
