论文摘要
发光太阳集合器（LSC）表明能够实现光谱转换，这可以量身定制太阳能光谱以更好地匹配光合作用的要求。但是，常规的LSC被设计为捕获而不是提取的光谱转换光。在这里，我们提出了一种基于在LSC底部表面上图案的突出和挤出的微孔阵列，提高了提高算法效率的有效方法。使用蒙特卡罗射线追踪，我们估计我们的园艺LSC（HLSC）的最大外部量子效率（EQE）为37.73％，相对于常规的平面LSC，相对于53.78％。此外，结构化的HLSC提供了弥漫性光，对植物生长有益。我们的微图案表面为LSC中的光捕获提供了解决方案，并为HLSC的实际应用提供了基础。
Luminescent solar concentrators (LSCs) have shown the ability to realize spectral conversion, which could tailor solar spectrum to better match photosynthesis requirements. However, conventional LSCs are designed to trap, rather than extract, spectrally converted light. Here, we propose an effective method for improving outcoupling efficiency, based on protruded and extruded micro-cone arrays patterned on the bottom surface of LSCs. Using Monte-Carlo ray tracing, we estimate a maximum external quantum efficiency (EQE) of 37.73% for our Horticulture-LSC (HLSC), corresponding to 53.78% improvement relatively to conventional, planar LSCs. Additionally, structured HLSCs provide diffuse light, beneficial for plant growth. Our micro-patterned surfaces provide a solution to light trapping in LSCs and a foundation for practical application of HLSC.
