Paper Abstract

Experimental techniques have been employed to characterize aging mechanisms in second surface mirrors for solar applications. Initial studies were focused on weathering (changes in the front surface of the glass due to exposure to moisture and pollutants in the environ-ment) and on solarization (changes in the optical absorption in the bulk of the glass due to incident sunlight). A newly initiated program is concerned with adhesion and corrosion at the silver-glass interface. The intent of all three studies is to provide sufficient understanding of the aging mechanisms to contribute to (a) the design of accelerated testing procedures, and (b) the selection of optimized solar materials. Experimental results and proposed aging mechanisms will be presented.
