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阶段I项目旨在将新技术商业化，用于使用新型的Oxi-Nenride化学和冷坩埚诱导熔化净化光伏（PV）太阳能电池的硅。该过程是基于通过采用导致高纯度钢产品的纯化策略来升级低成本冶金级硅的，它提出了一种新的方法来完善硅的新方法，从而消除了融化的互动相互作用，否则可以限制化学和运营温度的选择。预计，提出的技术会导致资本投资，生产投资，生产成本的成本能量，需要减少销售能源，降低了电子能量。以及潜在的环境破坏过程的重大减少。一旦成功商业化，新的炼油过程将在降低基于硅的太阳能电池的成本中发挥重要作用，这些太阳能电池的成本仍然占PV市场的90％以上。这项奖项是根据2009年《美国回收和再投资法》（公共法律111-5）资助的。
