Turning Sunlight into Electricity

Quartz is the starting material for the production of hyperpure polysilicon, the most important raw material for photovoltaics. Between quartz and hyperpure polysilicon lie a number of highly complex and technically sophisticated working steps – and in the case of WACKER over 50 years of experience. All combining to produce the best polysilicon available on the market.

The key stages in the production of hyperpure polysilicon:

1. Quartz

Silicon is the second most abundant element in the earth’s crust. In nature it occurs primarily as silicon dioxide (SiO2) in the form of quartz.

The purer the polysilicon, the more efficient is the solar cell.

The polysilicon produced by WACKER is 99.9999999 percent pure. It is an enabler for highly efficient solar cells that deliver a shorter energy payback time, a smaller carbon footprint and ongoing cost reductions. Over the lifetime of a solar cell, a kilogram of hyperpure polysilicon from WACKER can save on more than 7,000 kilograms of CO2 emissions.
