Improvement in the Flux Uniformity of the Solar Dish Concentrator System through a Concave Quartz Window by Du-zhong Nie, You-duo Peng, Jian Yan, Cheng-ji Mi, Yong-xiang Liu, Yong Tian

“…Finally, a further study on the sinusoidal quartz window scheme of all of the above optimal parameter schemes showed that when the installation position of the receiver relative to the dish concentrator was changed, the flux uniformity of the receiver could continue to improve. When the surface absorptivity of the receiver was reduced, the optical efficiency would be reduced. …”
