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).

这个小型企业创新研究第一阶段项目旨在将一项新技术商业化，该技术使用新型氮氧化物化学和冷坩埚感应熔炼来提纯用于光伏(PV)太阳能电池的硅。该工艺基于通过采用提纯策略来升级低成本的冶金级硅，从而获得高纯度的钢铁产品，提供了一种新的提炼硅的方法，消除了熔体-坩埚相互作用，否则限制了化学和操作温度的选择。拟议的技术预计将导致资本投资减少，生产成本降低，所需电能减少，以及潜在的破坏环境的工艺大幅减少。一旦成功商业化，新的精炼工艺将在降低硅基太阳能电池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(公共法律111-5)资助。
