Evonik Industries, SolarWorld Open New Solar Silicon Plant

Evonik Industries and SolarWorld have officially opened their new solar silicon plant in Rheinfelden (Baden, Germany). As part of the joint venture, Joint Solar Silicon (JSSI), the two companies are using an innovative process in the new plant that enables energy savings of up to 90% compared to conventional solar silicon production.

The integrated production network includes an Evonik monosilane plant. In the second plant in the network, JSSI takes the monosilane and uses it to manufacture solar silicon. The Rheinfelden facility will start with an annual production capacity of 850 metric tons of solar silicon.
