This Small Business Innovation Research (SBIR) Phase II seeks to develop a surface texturing technique that will significantly improve sunlight coupling into various types of solar cells. Surface textures are mandatory to record efficiencies in solar cells. The Omni-Directional Antireflective Coating (Omni-AR) solution showed a reduction in reflection in a large range of incident angles (omni-directional) over a broad spectral range (400-1200 nm). Improved solar cell efficiency of over 10% was demonstrated (experimentally). The broader impact/commercial potential of this project will be a low-cost, broad-spectrum, omni-directional and substrate-independent surface texture antireflective coating. It is expected to have a significant impact on current and future solar cell technologies. The ability to provide near ideal performance of antireflective coatings to solar cells without a vacuum process is a major step in reducing the cost of solar electricity. This solution-based deposition technique makes it possible to provide a single coating technology that should work with all types of solar cell materials and structures. This project will significantly improve the conversion efficiency in both current and future solar cells (~10%) with a minimum cost increase (~4%)."This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)."

这项小型企业创新研究（SBIR）II期旨在开发一种表面纹理技术，该技术将显着改善阳光耦合到各种类型的太阳能电池中。表面纹理必须记录太阳能电池的效率。 Omni方向防反射涂层（Omni-AR）溶液显示出在广泛的光谱范围内（400-1200 nm）的各种入射角（OMNI方向）的反射降低。证明了超过10％的太阳能电池效率（在实验上）。该项目的更广泛的影响/商业潜力将是低成本，宽光谱，全方向和独立于底物的表面纹理抗反射涂层。预计它将对当前和未来的太阳能电池技术产生重大影响。在没有真空过程的情况下，能够向太阳能电池提供抗反射涂层的理想性能的能力是降低太阳能成本的主要步骤。这种基于解决方案的沉积技术使得提供单个涂料技术，该技术应与所有类型的太阳能电池材料和结构一起使用。该项目将显着提高当前和未来太阳能电池的转化效率（约10％），最低成本提高（约4％）。“该奖项是根据2009年《美国回收和再投资法》（公法111-5）资助的。”
