Abstract
Antireflection of optically clear glass used in photovoltaic concentrator refractive secondary optical elements (SOEs) was investigated using the neutral-solution etch process. Test coupons and SOEs made from barium zinc glass, which does not solarize under ultraviolet exposure, were successfully etched at the center-point process variable conditions at 87 degrees C and 24 hours. Reflectance of the plano-plano coupons dropped from 7.7% to 0.8%,...
