This Small Business Innovation Research Phase I project aims to commercialize a new technology for purifying silicon for photovoltaic (PV) solar cells using a novel oxi-nitride chemistry and cold crucible induction melting. The process, based on upgrading low-cost metallurgical grade silicon by employing purification strategies that have led to high purity steel products, presents a new approach to refining silicon that eliminates melt-crucible interactions that otherwise limit the choice of chemistry and operational temperature.The proposed technology is projected to result in reduced capital investment, production cost reduction, reduction in electrical energy required; and a major reduction in potential environmentally damaging processes. The new refining process, once successfully commercialized, will play an important role in reducing the cost of silicon-based solar cells that still accounts for over 90% of the PV market.This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).

该小型企业创新研究第一阶段项目旨在利用新型氮氧化物化学和冷坩埚感应熔炼，将用于光伏 (PV) 太阳能电池的硅提纯新技术商业化。该工艺基于通过采用提纯策略升级低成本冶金级硅，从而生产出高纯度钢产品，提出了一种精炼硅的新方法，消除了熔体与坩埚之间的相互作用，否则会限制化学成分和操作温度的选择。拟议的技术预计将减少资本投资、生产成本和所需电能；并大幅减少潜在的环境破坏过程。新的精炼工艺一旦成功商业化，将在降低硅基太阳能电池的成本方面发挥重要作用，硅基太阳能电池仍占光伏市场的90%以上。该奖项由2009年美国复苏和再投资法案资助（公法 111-5）。
