SBIR Phase II: An Omni-Directional Antireflective Coating from Solutions

这项小型企业创新研究(SBIR)第二阶段旨在开发一种表面纹理技术，该技术将显著改善太阳光对各种类型太阳能电池的耦合。表面纹理是记录太阳能电池效率所必需的。全向抗反射涂层(Omni-AR)解决方案在宽光谱范围(400-1200 nm)的大范围入射角(全向)下显示出反射减少。太阳能电池效率提高了10%以上(实验)。该项目更广泛的影响/商业潜力将是一种低成本、广谱、全方位和与基材无关的表面纹理减反射涂层。预计这将对当前和未来的太阳能电池技术产生重大影响。能够为太阳能电池提供近乎理想的减反射涂层，而无需真空工艺，这是降低太阳能发电成本的重要一步。这种基于溶液的沉积技术使提供适用于所有类型的太阳能电池材料和结构的单一涂层技术成为可能。该项目将显著提高当前和未来太阳能电池的转换效率(~10%)，成本增加最小(~4%)。“该奖项由2009年美国复苏和再投资法案(公法111-5)资助。”

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)."
