Wittenberg, Germany February 18, 2013 PVA TePla AG is a world-leading manufacturer of solar and semiconductor silicon crystallization production equipment, vacuum and high-temperature system equipment, and it has developed technology for the production of silicon crystal growth systems. A decisive step. The technology named "MULTIPULLING" refers to a new technology that allows a variety of silicon crystals to be prepared simultaneously in a single process cycle with the aid of a supplementary feed device. At present, manufacturers in the solar energy industry are suffering from price wars. Using this new process method can significantly reduce the production cost of their crystals. These crystals are then prepared into solar wafers by another process.
Compared to other alternative methods of producing crystals, for example, compared to "continuous Czochralski Czochralski method", "MULTIPULLING" is characterized by lower complexity and significantly higher process stability, and can be significantly improved. Profitability in mass production in the solar field.
PVA TePla AG offers two different supplemental feeding devices for the "MULTIPULLING" process, which can be used to produce different types and sizes of polysilicon raw materials: a mobile "SiCharger" which is a mobile refeed system "Mobile Recharging" "System" (MRS) and a stationary feeder, also known as "Fixed Charging System" (FCS). Existing crystal production systems on the market can also be retrofitted with these additional equipment, and in the “MULTIPULLING†process, at the same time, production of at least two customer-specific crystals in one process cycle can be started. The key point of this technology is also the participation of the photovoltaic industry partners in the solar energy research project "Czechic-type production of Cz-pillar-based Czochralski straight-pull method with a focus on lower costs and thinner silicon wafers (CzSil) "taking the test. This feeding device features a solid structural design, ultra-high process accuracy and excellent user-friendliness with an intuitive user interface.
