Most optoelectronic components and consumer display devices require glass or plastic covers for protection against the environment. Optical reflections from these encapsulation layers can degrade the device performance or lessen the user experience. Here, we use a highly scalable self-assembly based approach to texture glass surfaces at the nanoscale, reducing reflections by such an extent so as to make the glass essentially invisible. Our nanotextures provide broadband antireflection spanning visible and infrared wavelengths (450–2500 nm) that is effective even at large angles of incidence. This technology can be used to improve the performance of photovoltaic devices by eliminating reflection losses, which can be as much as 8% for glass encapsulated cells. In contrast, solar cells encapsulated with nanotextured glass generate the same photocurrent as when operated without a cover. Ultra-transparent windows having surface nanotextures on both sides can withstand three times more optical fluence than comm...

自组装纳米纹理赋予玻璃窗和太阳能电池密封剂宽带透明度

大多数光电元件和消费类显示设备都需要玻璃或塑料外壳来保护环境。来自这些封装层的光反射会降低设备性能或降低用户体验。在这里，我们使用高度可扩展的基于自组装的方法在纳米级纹理玻璃表面，将反射减少到一定程度，从而使玻璃基本上不可见。我们的纳米纹理提供跨越可见光和红外波长（450-2500 nm）的宽带抗反射，即使在大入射角下也有效。该技术可用于通过消除反射损耗来提高光伏器件的性能，对于玻璃封装电池而言，反射损耗可高达 8%。相比之下，用纳米纹理玻璃封装的太阳能电池产生的光电流与无盖运行时相同。双面具有表面纳米纹理的超透明窗口可以承受比普通窗口高三倍的光通量……
