The Small Business Innovation Research (SBIR) Phase I project will develop a novel Omni-Directional Antireflective Coating (Omni-AR) to improve light collection in photovoltaic cells. The coating consists of a monolayer of microscale silica particles partially immersed into a film of spin-on glass. Its antireflection is broad spectrum and less dependent on sunlight incident angle, thus omni-directional. More importantly, the coating is prepared from solutions, ensuring its low cost. The research activities include 1) development of coating processes which allow large-area, uniform and close-packed coating of solar cells with monolayer silica particles; 2) optical simulation to optimize the designs of Omni-AR coatings and 3) testing of commercial polycrystalline silicon solar cells with Omni-AR coatings.Except anisotropically-etched pyramids on single-crystalline silicon, there is currently no cost effective method to produce surface texture on any other types of solar cells. Through this project, the technical feasibility and commercial potential of Omni-AR will be demonstrated. Such a low-cost, broad-spectrum, omni-directional and substrate-independent AR coating will have a significant impact on current and future solar cell technologies, including polycrystalline silicon, amorphous silicon, ribbon silicon, copper indium diselenide, cadmium telluride and organic semiconductors, by significantly improving their efficiency with a minimum cost increase. These solar cells currently have ~60% of the solar cell market.

小型企业创新研究（SBIR）I期项目将开发一种新型的Omni方向防反射涂层（Omni-AR），以改善光伏细胞中的光收集。涂料由一个浸入旋转玻璃膜的微观二氧化硅颗粒的单层组成。它的反射是广泛的，较少依赖于阳光入射角，因此是全方向的。更重要的是，涂层是根据解决方案制备的，以确保其低成本。研究活动包括1）开发涂层工艺，这些过程允许使用单层二氧化硅颗粒对太阳能电池进行大面积，均匀和封闭式涂层； 2）光学仿真，以优化Omni-Ar涂层的设计和3）使用Omni-Ar涂料测试商业多晶硅太阳能电池。概念各向异性蚀刻的金字塔对单晶硅的金字塔，目前没有任何其他类型的太阳能电池上的表面文本的成本有效方法。通过该项目，将展示Omni-AR的技术可行性和商业潜力。这种低成本，宽光谱，无综合和依赖于底物的AR涂层将对当前和未来的太阳能电池技术产生重大影响，包括多晶硅，多晶硅，无形硅，功能硅硅，铜硅化剂，二氧化碳imperium imperium imper，cadmium telluride和Organic Engiconductors a A IMINGING他们的效率都显着提高。这些太阳能电池目前拥有约60％的太阳能电池市场。
