The broader impact of this Small Business Innovation Research (SBIR) Phase I project is to increase the adoption of solar power by reducing the life-cycle cost of solar energy. The proposed work is to use a novel approach to improving the efficiency of any solar module with an additive manufacturing process. The technology tunes sunlight to improve its absorption and maximize its conversion into electric power. The proposed SBIR Phase I project will advance the development of a high-precision additive manufacturing process to create uniform optical layers for solar cells. A layer of nano-optical coating is created on either a plate-glass or polycarbonate substrate. The proposed coating restricts the wavelength distribution of incident photons to match the bandgap of mono- and polycrystalline silicon solar cells. The coating enhances coherence by embedding a nano-particle layer creating localized surface plasmon resonance on the crystalline silicon solar cell surface. Photons are scattered back to the solar cell with a one-dimensional distributed Bragg reflector.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这项小型企业创新研究（SBIR）I阶段项目的更广泛影响是通过降低太阳能的生命周期成本来增加太阳能的采用。 拟议的工作是使用一种新颖的方法来提高任何太阳能模块的效率。 该技术调节阳光以改善其吸收并最大程度地转化为电力。拟议的SBIR I期项目将推动高精度添加剂制造工艺的开发，以为太阳能电池创建均匀的光学层。 在板玻璃或聚碳酸酯基材上产生一层纳米光涂层。所提出的涂层限制了入射光子的波长分布，以匹配单晶和多晶硅太阳能电池的带隙。 涂层通过嵌入纳米粒子层在结晶硅太阳能电池表面上产生局部表面等离子体共振来增强连贯性。 光子以一维分布式的bragg反射器散落回太阳能电池。该奖项反映了NSF的法定任务，并认为使用基金会的知识分子优点和更广泛的影响审查标准，被认为值得通过评估。
