SolarWorld AG will invest a double digit million Euro amount to increase its manufacturing quality of solar wafers. Silicon-based solar wafers are the key component of solar cells. At its German site in Freiberg, SolarWorld is operating solar wafer plant, which will soon be equipped with diamond wire saws by the Swiss supplier Meyer Burger. Diamond wire saws increase the output and production speed. At the same time, costs are decreased and resources saved by reducing material losses. The result: solar wafers of particularly high quality, which SolarWorld will use for the production of high-efficiency solar cells at its site in Arnstadt, Thuringia.
