Wettenberg (euro adhoc) - (Wettenberg, February 18, 2013) - PVA TePla AG - a
manufacturer of solar silicon and semiconductor silicon crystallization systems
as well as vacuum and high-temperature systems - has achieved a major
technological enhancement of its crystal-growing systems for manufacturing
silicon crystals. The multipulling method is a technology with which several
silicon crystals can be manufactured from a single process cycle using a
recharging unit. With this method, customers in the highly price-driven solar
industry can significantly reduce their production costs for crystals from which
solar wafers are produced in a further process step.

For multipulling, PVA TePla offers two different recharging units for different
types and sizes of polysilicon raw material: a mobile Si charger - the Mobile
Recharging System (MRS) - and a stationary feeder - the Fixed Charging System
(FCS). Existing systems on the market can be fitted with these accessories, and
the multipulling process with at least two crystals per cycle can be introduced
along with customer-specific training. Key aspects of this technology were
tested with the involvement of project partners in the photovoltaics industry as
part of the Solar Valley research project "Optimization of the Czochralski
method for manufacturing monocrystalline silicon with regard to lower costs and
thinner wafers (CzSil)." The recharging unit is characterized by a compact
design, high process accuracy and user-friendliness with an intuitive user
interface.

Compared with alternative crystal-growing systems, such as the continuous
Czochralski method, multipulling is less complex, thus delivering much greater
process stability as well as significantly improved economic efficiency in
large-scale production for the solar industry.
