Concentrated photovoltaics allow a reduction of expensive semiconductor materials by collecting incident light through optical elements such as lenses and/or mirrors, which usually require bulky or heavy dual‐axis solar trackers, requiring dedicated installation sites. In this paper, we report a planar‐type concentrating photovoltaics with cylindrical lenses on which flexible GaAs solar cells are directly integrated on the curvilinear surfaces. The planar‐type concentrating system maintains both a focused beam width and angle invariably onto its integrated solar cells throughout the day. Computational and experimental studies at various incident angles prove the benefits of the design. Demonstrations of a custom‐built cylindrical lens solar tracker installed on a rooftop or sidewall of a building prove the feasibility of the proposed concept.

带有圆柱透镜的平面型聚光光伏电池与薄型柔性GaAs太阳能电池直接集成

集中式光伏通过通过光学元件（例如透镜和/或镜子）收集入射光来减少昂贵的半导体材料，光学元件通常需要笨重或笨重的双轴太阳跟踪器，需要专门的安装场所。在本文中，我们报告了一种带有圆柱透镜的平面型聚光光伏电池，其柔性GaAs太阳能电池直接集成在曲线表面上。平面型聚光系统全天始终将聚焦的光束宽度和角度保持在其集成太阳能电池上。在各种入射角度的计算和实验研究证明了设计的好处。安装在建筑物屋顶或侧壁上的定制圆柱透镜太阳跟踪器的演示证明了所提出概念的可行性。
