提出了一种测定发光太阳能聚光器（LSC）光学效率和损耗通道的新方法。尽管前景看好，但由于影响器件光学效率的各种机制，LSC尚未充分发挥其潜力。在这些损失通道中，逃逸锥和非单位量子产额损失通常是最主要的。为了进一步推动LSC领域的发展，必须独立地了解每个LSC的影响。到目前为止，研究人员只描述了LSC的总损失。在这里，提出了一种实验方法来分离每个单独损耗通道的贡献。实验装置与用于固体样品中荧光团的量子产率测量的相同。因此，该设置通常可用于已经参与LSC研究的研究小组。实验结果与蒙特-卡罗射线追踪法的计算结果进行了比较，验证了该方法的准确性。我们的实验方法可以对LSC的研究产生很大的影响，因为它提供了一种方法来揭示LSC的损耗通道，除了光效率。(C)2015作者由爱思唯尔公司出版
A novel experimental method is presented to determine the optical efficiency and the loss channels of a luminescent solar concentrator (LSC). Despite strong promise, LSCs have not yet reached their full potential due to various mechanisms affecting the device's optical efficiency. Among those loss channels, escape cone and non-unity quantum yield losses are generally the most dominant. To further advance the field of LSCs, it is vital to understand the impact of each independently. So far, researchers have only characterized the total loss in LSCs. Here, an experimental method is proposed to separate the contribution from each individual loss channel. The experimental apparatus is the same as used for quantum yield measurements of fluorophores in solid samples. Therefore, the setup is commonly available to research groups already involved in LSC research. The accuracy of this method is demonstrated by comparing the experimental results with Monte-Carlo ray tracing. Our experimental method can have a strong impact on LSC research as it offers a means to unveil the loss channels of LSCs in addition to the optical efficiency. (C) 2015 The Authors.
