Evonik Industries and The Silicon Mine (TSM) are planning to build the first integrated production facility for solar silicon in the Netherlands. In this integrated production network, Evonik’s Chemicals division will manufacture Siridion® chlorosilanes, from which TSM will produce high-purity solar silicon for the photovoltaics industry. Evonik will invest a high double-digit million euro amount.

“We see solar silicon as a large market with growth over the next few years,” said Klaus Engel, Ph.D., who is a member of the management board of Evonik Industries AG and is responsible for the Chemicals division. “In the mid-term, we aim to take hundreds of millions of euros in order to expand our good position massively in this attractive market.”

The integrated facility is being built at the DSM site in the municipality of Sittard-Geleen in Limburg province, one of the most important industrial zones in the Netherlands. At the site, Evonik Industries produces its high-purity Siridion chlorosilanes, which are converted by TSM into high-purity solar silicon by means of the well-proven Siemens deposition process. “The synergies of optimized integrated production between Evonik Industries and TSM at one of Europe’s largest chemical sites form the basis for the success of the project,” said Dietmar Wewers, Ph.D., head of Evonik’s Silanes Business Line.

Creating at least 400 jobs, TSM is planning an annual production of 3750 metric tons of high-purity solar silicon at the site in Sittard-Geleen. “That corresponds to 5% of the world market volume forecast for 2010,” said Gosse Boxhoorn, chairman of the management board of TSM, adding that annual production capacity could be increased in the long term to 14,000 metric tons of solar silicon.
