In this paper, a dynamic color-variable solar absorber is designed based on the phase change material SbSe. High absorption is maintained under both amorphous SbSe (aSbSe) and crystalline SbSe (cSbSe). Before and after the phase transition leading to the peak change, the structure shows a clear color contrast. Due to peak displacement, the color change is also evident for different crystalline fractions during the phase transition. Different incident angles irradiate the structure, which can also cause the structure to show rich color variations. The structure is insensitive to the polarization angle because of the high symmetry. At the same time, different geometric parameters enable different color displays, so the structure can have good application prospects.
本文基于相变材料SbSe设计了一种动态颜色可变的太阳能吸收器。在非晶态SbSe（aSbSe）和晶态SbSe（cSbSe）下均保持高吸收率。在导致峰值变化的相变前后，结构呈现出明显的颜色对比。由于峰值位移，相变过程中不同结晶分数的颜色变化也很明显。不同入射角照射该结构，也会使结构呈现出丰富的颜色变化。由于具有高对称性，该结构对偏振角不敏感。同时，不同的几何参数可实现不同的颜色显示，因此该结构具有良好的应用前景。
