没有主动冷却的聚光光伏系统的一个问题是太阳能电池组件上形成热点。这些热点是太阳能电池组件内辐射集中不均匀的结果。集中加热的总体影响是太阳能电池组件填充因子的降低以及随后系统整体效率的降低。在本文中，我们研究了一种使用半漫反射卷状反射元件来提高低聚光光伏系统性能的替代方案。我们的结果表明，反射器上与太阳能电池组件平面平行排列的滚动痕迹可提高光伏系统的性能。
One problem in concentrating photovoltaic systems without active cooling is the formation of hot spots on the solar module cells. These hot spots are a result of uneven concentration of radiation within the solar module cells. The overall effect of concentrated heating is the reduction in the fill-factor of the solar module cell and the subsequent decrease in the overall efficiency of the system. In this paper, we investigate one alternative of improving the performance of a low concentrating photovoltaic system using semi-diffuse rolled reflective elements. Our results indicate that rolling marks on the reflector aligned parallel to the plane of the solar module cell improve the performance of the photovoltaic system.
