Luminescent solar concentrators (LSCs) as alternatives to solar cells are suitable for photovoltaic windows. Generally semiconductor quantum dots are employed as emitters for LSC fabrication due to their advantages such as photostability, spectral tunability, and high photoluminescence quantum yield. In this paper, we used low cost and environmentally friendly N-doped carbon-dots (N-CDs) as phosphors to fabricate N-CDs/PMMA slab based luminescent solar concentrators. The high-performance N-CDs/PMMA slab based LSCs with an external optical efficiency of 12.23% could be achieved when the concentration of N-CDs within the PMMA matrix is 0.08 wt%. Our results showed that N-CDs/PMMA slab based luminescent solar concentrators make the practical use of LSCs more feasible because of the unique properties of N-CDs.

作为太阳能电池的替代品的发光太阳能集中器（LSC）适用于光伏窗户。通常，由于半导体量子点的优点，例如光稳定性，光谱可调谐性和高光致发光量子产率，它们被用作LSC制造的发射器。在本文中，我们使用了低成本且环保的N掺杂碳点（N-CD）作为磷光体，来制造基于N-CD / PMMA平板的发光太阳能聚光器。当PMMA基质中N-CD的浓度为0.08 wt％时，可以获得外部光学效率为12.23％的高性能N-CD / PMMA平板LSC。我们的结果表明，基于N-CD / PMMA平板的发光太阳能聚光器，由于N-CD的独特特性，使得LSC的实际使用更加可行。
