GCL Black Technology – PV Products

    GCL has been seeking diversity in the development of polysilicon product technology. The FBR method for granular silicon production is the fruitful result of over-ten-years efforts, of which GCL owns 100% intellectual property rights. The FBR method has enabled the mass production of granular silicon and brought about a production capacity of 30,000 tons. Compared with the traditional improved Siemens method, the FBR method bear significant advantages: lowering the investment of a new factory by 30%, reducing the comprehensive power consumption by 70%, and bringing down the carbon footprint by 75%. The sphere shape of granular silicon grantees good trafficking, and when Czochralski single crystals are fed, there is no problem of jamming, which enables smoother re-feedings. Wider use of granular silicon can advance the realization of “Carbon Neutral” in the production end of PV industry.

    147 patents, 2 international standards (SEMI), 3 national standards

    The conversion efficiency of a single reaction is 99%, meeting the standard of N-type single products.

    Xuzhou, Leshan and Baotou form a tripod of production bases, reaching a planned manufacturing capacity of 500,000 tons.

    FBR granular silicon won carbon footprint certification both in China and in France, setting the world's lowest carbon footprint record.
