SolarWorld AG: Start of Industrial Production of Solar-Grade Silicon

Joint Venture with Evonik Provides Efficiently and Innovatively Produced Raw Materials


Together with Evonik Industries AG the SolarWorld Group has given the green light for the industrial scale production of solar-grade silicon by inaugurating today the first production plant of its joint venture company Joint Solar Silicon GmbH & Co. KG (JSSI) in the Baden town of Rheinfelden. Using a new and innovative process the joint venture produces solar-grade silicon to be employed as a raw material in the solar power industry. The production process which is unique in the world is marked by a high level of efficiency: In comparison with conventional silicon production the JSSI technology can save up to 90 per cent of the energy employed. 'The combination of efficiency and quality is of strategic importance in order to help solar power technology to penetrate the energy industry more and more', emphasizes SolarWorld AG Chairman and CEO Dipl.-Ing. Frank H. Asbeck. 'It is thanks to technological progress of this kind that in a few years time solar power from the roof will have become cheaper for households than electricity from the wall socket.' With JSSI the group is consistently expanding its activities in the supply of raw materials while at the same time strengthening the business lastingly at the start of the solar value chain. 'From solar-grade silicon we produce thin wafers which we then process further into solar cells and modules', explains Frank Asbeck the integrated production chain of the group. In addition to JSSI the group also pursues other raw materials activities which include the industrial solar recycling at the Freiberg location. All these projects are designed to expand capacity while at the same time bringing about further progress in quality and efficiency. Undersecretary of State Müller: 'Entry into industrial value creation' Michael Müller, Parliamentary Undersecretary of State in the Ministry of the Environment, welcomes the investments of the two companies in Rheinfelden: 'It is a good thing for the photovoltaic industry to have stopped being a niche player and to have entered into comprehensive industrial scale value creation'. The new technology was developed by JSSI in cooperation with leading universities. The joint venture produces solar-grade silicon from monosilane starting its industrial production with an annual capacity of 850 tons. The total investment volume is in the range of a double digit million EUR amount. Evonik Industries AG holds 51 per cent and SolarWorld AG 49 per cent in the JSSI joint venture. About SolarWorld AG The SolarWorld AG group of companies (ISIN: DE0005108401) is a world leader in high quality solar power technology. The company is involved at all levels of the solar value chain and combines all activities of the solar industry from silicon as the raw material to turn-key solar power systems. SolarWorld AG is represented in all the world’s solar growth markets. The group is exclusively dedicated to its core business of photovoltaic power generation operating production facilities in Germany, USA and South Korea. They in turn supply the SolarWorld AG sales offices in Germany, Spain, USA, South Africa and Singapore. The central element of the business in addition to the sale of turn-key solar systems and solar modules to the trade is the distribution of solar silicon wafers to the international solar cell industry.
