SST Polysilicon Deposition Shows Outstanding Quality Results
Polysilicon complies with an "electronic grade" specification
Being the dominant raw material of the solar industry, Polysilicon must be of increasingly higher quality to meet the requirements for improvement in efficiency of multi- and monocrystalline solar cells. The demand for higher volume and more cost-effective production technologies has advanced the development of innovative purification methods of metallurgical silicon.
An especially innovative technology in this field is offered by Schmid Silicon Technology GmbH (SST), which allows producing Polysilicon of the highest quality at a substantially reduced manufacturing cost due to its efficient process and very low power consumption.
Only two months upon the "first Silicon out" SST can now offer at its own production plant in Schwarze Pumpe, Saxony, featuring the Monosilane-based CVD deposition, Polysilicon, which already meets the requirements of the so-called "11N" material. Herewith, the Polysilicon complies with an "electronic grade" specification and, thus, can be even used in the semiconductors industry.
The fast achievement of this quality provides another clear evidence for the advantage of the SST Monosilane-based technology vs. conventional Polysilicon production methods based on Siemens technology.
According to Jochem Hahn, COO of SST, these results come as no surprise, since through the disproportionation of trichlorosilane to monosilane alone this purification effect can be achieved easily and steadily due to the physical/chemical mechanisms.
Another milestone of this improved Polysilicon production technology is the achievement of the deposition rate on silicon rods of 1mm/h, resulting in low power consumption. Both results strongly confirm expected figures of SST technology, which herewith makes a substantial contribution to the overall cost reduction of up to 40%.
About Schmid Silicon Technology GmbH (SST):
Founded in 2006 by Christian Schmid, SST is about to enter in a strong growth phase. Schmid Silicon Technology is the leading technology provider with respect to high-end solar (and, if demanded, electronic) grade Polysilicon and Monosilane gas production as well as plant engineering (turnkey).
In addition to the patented technology SST supplies together with its partner M+W Group the overall know-how for planning and realization of Turnkey Plants for the Polysilicon and Monosilane production.
Project planning and realization for Polysilicon and Monosilane productions are among SST´s core expertise (starting with the pre-basic design and ending with the qualification of the key staff and after sales services).
Furthermore, SST supplies Single-Equipment for Polysilicon production. SST will enable polysilicon-producers to achieve cost reductions of up to 40% compared to traditional production methods.
The Schmid Silicon Technology GmbH is the only equipment supplier investing in its own technology. The company invests in the production plant in Saxony, Germany, designed to showcase its advanced Monosilane technology. This pilot production is planned to start the full profitable Monosilane and Polysilicon production in 2011. This worldwide unique Polysilicon plant allows an optimal technology design as well as continuous process improvement and new technological innovations.
