Cornerstone laid: Wacker is responding to the photovoltaics boom by further expanding polysilicon production
To provide the photovoltaics industry with a completely new way of producing silicon crystals, Wacker Polysilicon has also developed a novel process for granular polysilicon production. Based on the fluidized-bed technique (with trichlorosilane as feedstock), the process is being tested on an industrial scale at two pilot reactors. Granular silicon is ideal for continuous crystallization processes. Wacker has been producing hyperpure polycrystalline silicon for the semiconductor industry at its Burghausen site for over 50 years
