| 针对彩色钙钛矿太阳能电池的美学特征，对该太阳能电池的纳米级色彩调节进行了研究。利用Fano共振原理以及在钙钛矿太阳能电池中采用Fano微纳砷化铝光栅结构，模拟出了不同色彩的钙钛矿太阳能电池。模拟结果表明，调节Fano微纳砷化铝光栅结构的周期和槽深，可控制钙钛矿太阳能电池的反射峰位置和峰宽，并且峰位的控制精度达到了1 nm，同时全可见波段范围的反射峰宽小于20 nm，蓝、绿、红三种颜色的钙钛矿电池的吸收损耗分别仅为1.3%、6.1%和7.7%。因此，该Fano微纳砷化铝结构的彩色钙钛矿太阳能电池可应用于建筑墙体、窗户和屋顶的装饰。 |

| The colorful perovskite solar cell has aesthetic characteristics. The nanoscale color adjustment of colorful perovskite solar cells is realized by simulating the design of Fano AlAs nanograting. Theoretical simulation shows that by adjusting the period and groove depth of the Fano AlAs nanograting structure based on the strong Fano resonance principle, an ultrafine control with a 1 nm wavelength resolution of the reflection peaks can be achieved and the reflection peak width of the Fano grating is only less than 20 nm in a wide range of visible light. Moreover, the absorption losses of the blue, green, and red perovskite solar cells are only 1.3%, 6.1% and 7.7%, respectively. The described outcome exhibits significant potential to develop high-performance clean energy devices for walls, windows, and roofs. |
