Scientists from Fraunhofer IISB, Wacker Chemie and Alzchem say unwelcome metals enter the silicon primarily through coating of the quartz crucible. The finding could enable manufacturers to make predictions about the quality of silicon blocks.
At the Solar Power Summit in Brussels today, the industry group said it is preparing to launch a supply-side oriented industrial policy for the PV sector in Europe. The manufacturing sector on the continent has been hard hit since 2012, and has been buffeted by a range of unfavorable policy decisions.
The German poly manufacturer expects to increase sales in the current financial year, however EBITDA is expected to be down as much as 20% as average prices for polysilicon will continue to decline.
If the German polysilicon manufacturer is the ‘Supplier A’ referred to in the Chinese panel maker’s annual report, Wacker has negotiated a near $33 million settlement from arbitration. As part of the settlement, Wacker will continue to supply its counterpart with poly up to 2028.
Wacker Chemie AG has said it is gradually ramping up production at its beleaguered U.S. polysilicon production site, with product expected to be again available in Q2. The shutdown has affected its Q1 earnings, with sales down 18% compared to a year ago.
German chemical supplier has raised its financial outlook for the year for the second time in three months, on the back of a strong third quarter. The company is now forecasting a full year EBITDA (earnings before interest, tax, depreciation and amortization) of €1 billion.
Wacker’s polysilicon division saw its sales decrease in the second quarter, despite the group’s turnover growth.
