The Silicon Market: the reason to produce Polysilicon


The main part of PV market uses monocrystalline and multicrystalline silicon (both derived from Polysilicon)

The total production of polysilicon in 2005 has been ~ 32,000 tons. This value will increase dramatically as depicted in the following diagram (where polysilicon production is divided into different companies).



  HEMLOCK   TOKUYAMA   SUMITOMO
  WACKER   MEMC   CHINA

The polysilicon demand in the last years has increased too and the gap between Capacity and Demand has produced an increasing shortage of Polysilicon.
