Luminescent solar concentrators (LSCs) are complementary sunlight collectors for photovoltaics (PVs). Emissive fluorophores embedded in a transparent waveguide collect solar radiation over a large area and convert it into luminescence directed to the PV cells that frame the waveguide's edges. Among various fluorophores, perovskite nanocrystals (PNCs) show considerable potential for LSCs thanks to their wide size/composition/shape tunable broad absorption spectrum ranging from UV to near‐infrared, which significantly overlaps with the solar spectrum. They also feature high brightness with a photoluminescence quantum yield of up to 100% and ease of fabrication through wet chemistry approaches. In addition, PNCs can be engineered to minimize the absorption/emission overlap, which is the key to suppressing energy losses caused by reabsorption. Here, the structure and properties of PNCs and then correlate them with LSC performance is presented. The synthesis of PNCs using wet‐chemistry approaches and summarize the latest developments of PNCs‐based LSCs, categorized by the engineering strategies of PNCs and the design of the LSC configurations is critically reviewed. Finally, it is described major challenges and perspectives for future work, outlining the rational design, synthesis, PNC loading, surface engineering, and machine‐learning‐based tuning of PNC‐LSC.

钙钛矿纳米晶体：发光太阳能聚光器的机遇


发光太阳能聚光器 (LSC) 是光伏发电 (PV) 的补充阳光收集器。嵌入透明波导中的发射荧光团收集大面积的太阳辐射，并将其转换成荧光，直接射向构成波导边缘的光伏电池。在各种荧光团中，钙钛矿纳米晶体（PNC）由于其宽尺寸/成分/形状可调的宽吸收光谱（从紫外到近红外）（与太阳光谱显着重叠），在LSC方面显示出巨大的潜力。它们还具有高亮度和高达 100% 的光致发光量子产率，并且易于通过湿化学方法制造。此外，PNC 可以设计成最大限度地减少吸收/发射重叠，这是抑制重吸收引起的能量损失的关键。在这里，介绍了 PNC 的结构和特性，然后将它们与 LSC 性能相关联。使用湿化学方法合成 PNC，并总结了基于 PNC 的 LSC 的最新进展，按照 PNC 的工程策略进行分类，并对 LSC 结构的设计进行了严格的审查。最后，描述了未来工作的主要挑战和前景，概述了 PNC-LSC 的合理设计、合成、PNC 加载、表面工程和基于机器学习的调整。
