| Dow Corning introduces new solar grade silicon material Dow Corning introduces new solar energy technology: a solar-grade, SoG, silicon derived from metallurgical silicon that exhibits good solar cell performance characteristics when blended with traditional polysilicon feedstock. This new silicon feedstock material, Dow Corning PV 1101 SoG Silicon, is the feedstock produced from such technology using large scale manufacturing processes. For several years, the primary obstacle to the growth of solar energy has been the constrained availability of silicon, the key raw material used in the production of solar cells. Until now the solar industry has relied on the supply of polycrystalline silicon, a high-grade purity product, originally developed for the semiconductor industry. This has meant that the solar industry has in turn been subject to resource restraint. The launch of PV 1101, produced from a very different route, will alleviate that restraint and offer a new source of supply as well as new technical and business options for the solar industry. write your comments about the article :: © 2006 Construction News :: home page |
