Luminescent solar concentrators (LSCs) are optical systems that absorb, convert, and concentrate solar light by means of photoluminescence of an emitting material embedded in a transparent waveguide. LSCs combine large possibilities of variation of shape, flexibility, color, and transparency and can operate under direct or diffuse light. LSCs were actively investigated in the period 1975–1985 in view of photovoltaic (PV) conversion. After 20 years of sleep, research on LSCs has reemerged in the first years of the millennium driven by their potential application for PV conversion in built environment. Research on LSCs aims at the development of new active and passive components, namely emitting and light‐guiding materials, and at the reduction of the loss factors associated with the elemental processed involved in the operation in order to improve power conversion efficiency. After a brief historical account, the operating principles, characterization, components, technology, and applications are reviewed. Finally, the performance of LSCs are critically discussed in a global perspective with particular emphasis on the basic contradiction between light concentration and conversion efficiency leading to some suggestions for future development of the topic.

发光太阳能集热器：Qu Vadis？

发光太阳能集中器（LSC）是通过嵌入透明波导中的发光材料的光致发光来吸收，转换和聚集太阳光的光学系统。LSC结合了形状，柔韧性，颜色和透明度变化的很大可能性，并且可以在直接或漫射光下运行。鉴于光伏（PV）转换，在1975年至1985年期间对LSC进行了积极的研究。经过20年的睡眠后，由于在建筑环境中将其应用于光伏转换的潜在应用，对LSC的研究在千年的头几年重新兴起。LSC的研究旨在开发新的有源和无源组件，即发光和导光材料，并且减少了与操作中涉及的元素处理有关的损耗因子，以提高功率转换效率。在简短的历史记录之后，将回顾操作原理，特征，组件，技术和应用。最后，在全球范围内对LSC的性能进行了严格的讨论，特别强调了光浓度和转换效率之间的基本矛盾，从而为该主题的未来发展提出了一些建议。
