While luminescent solar concentrators (LSCs) have a simple architecture—a transparent matrix embedding a luminescent fluorophore coupled with solar cells at the lateral side of the LSC slab—multiple paths for possible light losses exist. These are inherently interconnected, and in the past, limited the interest in this device, due to the gap between the theoretical possibilities and experimental achievements. This gap was a result, primarily, of the optical features of the luminescent dyes, since conventional organic luminophores are affected by limited performance in LSC devices. The rise of a wide portfolio of optically active inorganic nanomaterials in the last decade provides an alternative to organic dyes and has lead to a renaissance in the role of LSCs among the unconventional solar energy conversion devices. This paper reviews the latest results in the development of LSCs based on different classes of nanomaterials, focusing on the specific features and critically analyzing the pros and cons of the proposed structures. Particular attention is devoted to the role of the luminescence properties, e.g., the Stokes shift and the photoluminescence quantum yield, with respect to the performance of the LSC device. Future challenges to the successful employment of these devices for building integrated photovoltaics are also discussed.

发光太阳能聚光器的复兴：无机纳米材料的作用

尽管发光太阳能聚光器（LSC）具有简单的体系结构-在LSC平板的侧面嵌入有与太阳能电池耦合的发光荧光团的透明矩阵-存在用于可能的光损耗的多条路径。由于理论上的可能性和实验成果之间的差距，它们之间固有地相互联系，并且在过去限制了对该设备的兴趣。该间隙主要是由于发光染料的光学特性造成的，因为常规的有机发光体受LSC器件性能受限的影响。在过去的十年中，光学活性无机纳米材料的广泛组合提供了有机染料的替代品，并导致了非常规太阳能转换设备中LSC的角色的复兴。本文回顾了基于不同类别的纳米材料的LSCs开发的最新结果，重点关注其特定特征并严格分析了所提出结构的优缺点。关于LSC器件的性能，特别关注发光性质例如斯托克斯位移和光致发光量子产率的作用。还讨论了成功使用这些设备来构建集成光伏电池的未来挑战。关于LSC设备的性能。还讨论了成功使用这些设备来构建集成光伏电池的未来挑战。关于LSC设备的性能。还讨论了成功使用这些设备来构建集成光伏电池的未来挑战。
