Luminescent solar concentrators (LSCs) are a class of wave-guiding devices that can harvest solar light and concentrate it to targeted smaller areas. When coupled with photovoltaic devices (PVs), LSCs hold the potential to be integrated into various application setups, especially for building facade integration toward net-zero-energy buildings. Developing reliable LSC fabrication methods with easy scalability, high adaptability, and device controllability has been an important research topic. In this work, we report an ultrasonic nebulization-assisted spray deposition technique to fabricate quantum dot (QD)-based LSCs (QD-LSCs). This method allows for the production of high-performance QD-LSCs with different device dimensions and geometries. In addition, the quality of the QD thin-film coating layer is relatively independent of the concentration and volume of the coating QD ink solution, allowing for deliberate programming and performance optimization of the resulting QD-LSC devices. We anticipate that this ultrasonic spray coating method can be widely applied to the manufacturing of high-quality LSC devices that are integrable to various applications.
发光太阳能聚光器（LSCs）是一类能够收集太阳光并将其聚集到目标较小区域的波导装置。当与光伏器件（PVs）结合使用时，LSCs有潜力集成到各种应用设置中，特别是用于向净零能耗建筑的建筑立面集成。开发具有易于扩展、高适应性和器件可控性的可靠LSC制造方法一直是一个重要的研究课题。在这项工作中，我们报告了一种超声雾化辅助喷雾沉积技术来制造基于量子点（QD）的LSCs（QD-LSCs）。这种方法能够生产具有不同器件尺寸和几何形状的高性能QD-LSCs。此外，量子点薄膜涂层的质量相对独立于涂层量子点油墨溶液的浓度和体积，从而能够对所得的QD-LSC器件进行有意的编程和性能优化。我们预计这种超声喷雾涂层方法可广泛应用于制造可集成到各种应用中的高质量LSC器件。
