In a three-step process, rice hulls were purified and then converted into upgraded metallurgical silicon suitable for ingot production using directional solidification and solar-grade wafers. Pilot production of this new solar cell feedstock has successfully demonstrated solar cell efficiencies comparable to high purity polysilicon produced by conventional means. The design and fabrication of a production-scale operation follows this pilot demonstration.
