太阳能电池的吸收效率在过去已经通过蛾眼纳米图案的仿生学得到了提高。然而，自然界中仍有许多光学纳米结构有待研究用于太阳能应用。特别是“玻璃翼”Greta Oto蝴蝶，它的翅膀具有最小的眩光效应，在这里研究新兴的光伏和聚光器光伏设计的好处。光伏技术，如薄膜和低聚光系统（用于将光聚焦到光伏材料的较小区域的固定光学器件），包含折射光学组件（首先包括保护盖玻璃），因此需要优化传输的抗反射涂层。了解玻璃翅蝴蝶纳米结构翅膀的哪些方面允许其异常低的反射率，这将从新的和现有的光伏技术中开辟一个重要的能源来源。 我们利用扫描电子显微镜图像，分光光度法和测量与光伏材料耦合的翅膀的外部量子效率信号，表征了玻璃翼蝴蝶纳米结构的光学性质。
Solar cell absorption efficiencies have in the past been improved by the biomimicry of moth eye nano-patterns. There are however still many optical nanostructures within nature yet to be investigated for solar energy applications. The ‘Glasswing’ Greta Oto butterfly in particular boasts a minimal glare effect of its wings, which is investigated here for benefits to emerging photovoltaic and concentrator photovoltaic designs. Photovoltaic technologies such as thin film and low concentrator systems (stationary optics used to focus light to smaller areas of photovoltaic material) incorporate refractive optical components (including firstly the protective cover glass) and hence require antireflective coatings that optimize transmission. Understanding what aspects of the Glasswing butterflies nanostructured wings allow for their exceptionally low reflectivity opens up a significant resource of energy from new and existing photovoltaic technologies. We have characterized the optical properties of the Glasswing butterfly nanostructures utilizing Scanning Electron Microscope images, Spectrophotometry and measurements of the External Quantum Efficiency Signal of the wings coupled with photovoltaic material.
