This work reports on a diameter dependence analysis of the performance as luminescent solar concentrators of three self-fabricated polymer optical fibers (POFs) doped with a hybrid combination of dopants. The works carried out include the design and self-fabrication of the different diameter fibers; an experimental analysis of the output power, of the output irradiance and of the fluorescent fiber solar concentrator efficiency; a comparison of the experimental results with a theoretical model; a study of the performance of all the fibers under different simulated lighting conditions; and a calculation of the active fiber length of each of the samples, all of them as a function of the fiber core diameter. To the best of our knowledge, this paper reports the first analysis of the influence of the POF diameter for luminescent solar concentration applications. The results obtained offer a general perspective on the optimal design of solar energy concentrating systems based on doped POFs and pave the way for the implementation of cost-effective solar energy concentrating devices.
这项工作报道了对三种自行制备的、掺杂了混合掺杂剂的聚合物光纤（POF）作为发光太阳能聚光器的性能进行的直径依赖性分析。所开展的工作包括不同直径光纤的设计与自行制备；对输出功率、输出辐照度和荧光光纤太阳能聚光器效率进行实验分析；将实验结果与理论模型进行比较；研究所有光纤在不同模拟光照条件下的性能；以及计算每个样品的有源光纤长度，所有这些均作为光纤芯直径的函数。据我们所知，本文首次分析了POF直径对发光太阳能聚光应用的影响。所获得的结果为基于掺杂POF的太阳能聚光系统的优化设计提供了总体视角，并为实施具有成本效益的太阳能聚光装置铺平了道路。
