In this review, the concept of utilization of solar spectrum in order to increase the solar cell efficiency is discussed. Among the three mechanisms, down-shifting effect is investigated in detail. Organic dye, rare-earth minerals and quantum dots are three most popular down-shift materials. While the enhancement of solar cell efficiency was not clearly observed in the past, the advances in quantum dot fabrication have brought strong response out of the hybrid platform of a quantum dot solar cell. A multiple layer structure, including PDMS as the isolation layer, is proposed and demonstrated. With the help of pulse spray system, precise control can be achieved and the optimized concentration can be found.
在本综述中，讨论了利用太阳光谱以提高太阳能电池效率的概念。在这三种机制中，对向下转换效应进行了详细研究。有机染料、稀土矿物和量子点是三种最常用的向下转换材料。虽然过去并未明确观察到太阳能电池效率的提高，但量子点制造技术的进步已在量子点太阳能电池的混合平台上引发了强烈反响。提出并展示了一种包括聚二甲基硅氧烷（PDMS）作为隔离层的多层结构。借助脉冲喷雾系统，可以实现精确控制并找到最佳浓度。
