光捕获是用于增强许多光伏（PV）装置中的太阳能收集效率的常用技术。在本文中，我们提出了多层光捕获结构的设计，可以改造，或直接集成到晶体或非晶硅太阳能电池板上，以增强在正常和极端入射角的光学收集。这种方法可以提高太阳能电池板的日常光学收集性能与内部集成的光捕获结构和没有高达7.18%和159.93%，分别。这些改进预测了超出许多研究水平和商业部署的光捕获技术的增强。我们通过将多层光学器件与高折射率材料相结合，进一步增强了这一性能，以实现比领先的陷光结构高出高达32.20%的每日光学收集。我们的附加光捕获设计可以实现旧光伏技术的可重复性，并且可以定制以在建筑物外部的独特角度范围内或在无人机等应用的广泛入射角范围内进行最佳操作。
Light trapping is a commonly used technique for enhancing the efficiency of solar collection in many photovoltaic (PV) devices. In this paper, we present the design of multi-layer light trapping structures that can potentially be retrofitted, or directly integrated, onto crystalline or amorphous silicon solar panels for enhanced optical collection at normal and extreme angle of incidence. This approach can improve the daily optical collection performance of solar panel with and without internally integrated light trapping structure by up to 7.18% and 159.93%, respectively. These improvements predict an enhancement beyond many research level and commercially deployed light trapping technologies. We further enhance this performance by combining our multi-layer optics with high refractive index materials to achieve a daily optical collection of up to 32.20% beyond leading light trapping structures. Our additive light trapping designs could enable the upgradeability of older PV technologies and can be tailored to optimally operate at unique angular ranges for building exteriors or over a wide range of incidence angle for applications such as unmanned aerial vehicles.
