Optical Changes in Cerium-Containing Glass as a Result of Accelerated Exposure Testing

Optical Changes in Cerium-Containing Glass as a Result of Accelerated Exposure Testing

Research output: Contribution to conference › Paper

Abstract

The purpose of this paper is to report changes in the optical transmission spectrum (solarization) of commercial low-iron cerium containing glass (CG). UV absorption by CG has been shown to reduce yellowing rates of EVA polymeric pottants in PV modules resulting from UV radiation. Absorption and fluorescence spectra of CG change with exposure to UV light in the glass matrix. Solarization of CGcould cause changes in the glass transmission that may result in changes in the UV protection and the efficiency of the module. We are studying the solarization of glasses in a variety of accelerated light exposure chambers at intensities ranging from 1 to more than 1000 suns. Measurements made at various stages of the accelerated exposure tests are presented.
