论文摘要
我们使用现代进化算法优化了光伏设备的多层抗反射涂层。我们采用一种严格的方法来表明，特定的结构特别是规律的，以一种非常系统的方式在非常广泛的条件下自发出现。结构的规律性允许对设计的运作方式进行彻底的物理分析。这允许理解中心部分是用于光缓冲液的光子晶体，外层的目的是减少外介质与光子晶体支持的BLOCH模式之间的阻抗不匹配。这表明优化如何建议新的设计规则并被视为灵感的来源。最后，我们使用易于部署的技术制造这些结构。
We optimize multilayered anti-reflective coatings for photovoltaic devices, using modern evolutionary algorithms. We apply a rigorous methodology to show that a given structure, which is particularly regular, emerge spontaneously in a very systematical way for a very broad range of conditions. The very regularity of the structure allows for a thorough physical analysis of how the designs operate. This allows to understand that the central part is a photonic crystal utilized as a buffer for light, and that the external layers have the purpose of reducing the impedance mismatch between the outer media and the Bloch mode supported by the photonic crystal. This shows how optimization can suggest new design rules and be considered as a source of inspiration. Finally, we fabricate these structures with easily deployable techniques.
