论文摘要
对可再生能源的需求不断增长，是促进将太阳能收集材料与人类生活环境（例如建筑集成的光伏电动机（BIPV））相结合的技术。这对开发彩色覆盖的要求提出了效率和美学之间的权衡，为大规模应用结构颜色技术提供了新的阶段。在这项研究中，我们研究了使用光子玻璃（随机的单分散介电微球）的理论可行性，作为太阳能收集的彩色覆盖物。基于众多光学模拟，我们评估了具有不同参数的光子玻璃的颜色和平均太阳透射率（AST）。结果表明，使用具有相对较高的折射率的非吸收微球，约3μm厚的光子玻璃可以使颜色具有50多个颜色，同时使AST保持在80％左右。此外，我们证明，由于短距离结构相关性，光子玻璃可以产生紫色，蓝色，青色，浅绿色和灰色，但无助于黄色和红色的色调。最后，阐明了几种增强方法的效果，并展示了扩展颜色范围的可能方法。这些结果为使用光子眼镜的结构颜色实现提供了综合指南，尤其是在太阳能材料的着色中。
The increasing demand for renewable energy is promoting technologies that integrate solar energy harvesting materials with the human living environment, such as building-integrated photovoltaics (BIPVs). This places requirements on developing colored covers with a trade-off between efficiency and aesthetics, providing a new stage for the large-scale application of structural color technologies. Here in this study, we have investigated the theoretic feasibility of employing the photonic glass, a random packing of monodisperse dielectric microspheres, as the colored cover for solar energy harvesting. Based on numerous optical simulations, we have evaluated the color and average solar transmissivity (AST) of the photonic glasses with varying parameters. Results show that using non-absorbing microspheres with relatively high refractive index, about 3 μm thick photonic glasses could enable colors with lightness over 50 while keeping AST at around 80%. Besides, we demonstrate that due to the short-range structural correlation, photonic glasses could generate purple, blue, cyan, light green, and grey colors, but cannot help with yellow and red color hues. Finally, the effects of several enhancement methods are clarified, and possible ways for expanding the color range are demonstrated. These results provide a comprehensive guide to the practical implementations of structural color using photonic glasses, particularly in the colorization of solar energy materials.
