Colored photovoltaic (PV) modules with integrated disordered coatings exhibit attractive potential for generating renewable electricity. However, most existing studies on these modules rely on the assumption that the disordered coatings are random systems, neglecting the effects of spatial correlation. In this work, we thoroughly investigate the effects of spatial correlation on the color properties and performance of colored PV modules with integrated disordered coatings, using the full-wave electromagnetic simulation techniques. Our findings indicate that increasing the degree of spatial correlation results in a sharper and narrower reflectance peak, while having a negligible impact on the peak position. This trend suggests that the spatial correlation offers an alternative strategy for producing more vivid color, although it is less effective in expanding the color range. On the other hand, the spatial correlation has little impact on the power conversion efficiency (PCE) of PV modules. Therefore, it is feasible to produce colored PV modules with more vivid colors without significantly affecting the PCE by simply adjusting the degree of spatial correlation.

空间相关性对集成无序介质彩色光伏组件性能的影响


带有集成无序涂层的彩色光伏 （PV） 组件在产生可再生电力方面表现出诱人的潜力。然而，关于这些模块的大多数现有研究都依赖于无序涂层是随机系统的假设，而忽略了空间相关性的影响。在这项工作中，我们使用全波电磁仿真技术彻底研究了空间相关性对具有集成无序涂层的彩色光伏组件的颜色特性和性能的影响。我们的研究结果表明，增加空间相关性的程度会导致反射峰更尖锐和更窄，而对峰位置的影响可以忽略不计。此趋势表明，空间相关性为生成更鲜艳的颜色提供了一种替代策略，尽管它在扩展颜色范围方面效果较差。另一方面，空间相关性对光伏组件的功率转换效率 （PCE） 影响很小。因此，只需调整空间相关性的程度，即可生产出色彩更鲜艳的彩色光伏组件，而不会显著影响 PCE。
