    • PV Crystalox Solar operates its in-house polysilicon production plant in Bitterfeld – the heart of Germany's solar valley
    • The facility is unique in Europe, being the first to use modifications to the established Siemens process, where operations have been optimised for the exclusive production of solar grade polysilicon
     

  • Image of the number twoIngot production

    • The Group's ingot production facilities are based in Oxfordshire, UK, where four production plants are in operation
    • Multicrystalline silicon ingots are directionally solidified, under carefully controlled conditions, from molten, high-purity polysilicon, in production systems designed and manufactured by Crystalox Limited
    • Continual innovation and development ensures PV Crystalox Solar's leadership in the manufacture of superior quality silicon ingots

  • Image of the number threeBlock production

    • The sectioning of ingots into blocks is carried out at the Group's facilities in the United Kingdom and by PV Crystalox Solar's partners in Japan
    • Quality checks are carried out throughout ingot and block production resulting in consistent, high performance multicrystalline wafers

  • Image of the number fourWafer production

    • Wafering of the blocks takes place at the Group's wafering facility, PV Silicon in Erfurt, Germany, and in Japan by our wafering subcontractors
    • Wafers are manufactured to meet the highest standards

  • Image of the number fiveExternal sales

    • PV Crystalox Solar supplies multicrystalline silicon wafers to major PV companies in Europe and Asia from its wafering facilities in Germany and Japan. From these strategic locations, PV Crystalox Solar collaborates closely with its customers to ensure standards are maintained and that any technological developments are passed on quickly
