In a bid to meet customers’ future needs for top- quality polysilicon to make high-efficiency solar cells, Wacker has planned capacity expansion. Wacker Chemie AG has started construction work on a fully integrated polysilicon-production site in the USA, planned to be completed by late 2013 with an annual capacity of 15,000 tons. As announced earlier, WACKER is also expanding its German facilities at Burghausen and Nu¨nchritz. The total increase there will be 10,000 tpa by 2012. As a result, WACKER’s overall hyperpure polysilicon capacity will rise to 67,000 tons by 2014.
