Outstanding metallization process
for high volume cell production
Renewable energies use the natural energy ows on the earth in small parts. The inexhaust-
ible power of the sun is ready for regeneration of these. All life on earth takes its energy
from the power of the sun. Solar energy can also be used directly. Solar cells in photovoltaic
plants, solar thermal power plants and solar collectors use solar radiation without detours
and convert the radiation energy into electricity or heat.
In the fast-paced world of solar cell manufacturing, Rehm is continuously developing new
equipment to match the demands of our customers. Rehm has provided dryers and ring
furnaces to the metallization lines for over 10 years. Since 2005 we have dedicated ourselves
to the design and manufacturing of dryers for print lines. Drying the paste and handling the
VOC’s of the solar pastes is an extremely important part of the metallization and contributes
largely to a good efciency. For a sustainable handling of the VOC’s, Rehm has developed
a Thermal Oxidizer, operating at a 99,5 % oxidization efciency. Our Firing Furnaces have a
very good reputation in the market place. Apart from an increasing and loyal customer base,
Rehm Firing Furnaces are used in famous institutions such as the Fraunhofer ISE in Freiburg,
Germany. The Rehm Firing Furnaces provide a large process window for the optimization of
the ring prole, while allowing an increased wafer throughput of up to 5300 wafers/hour.
The Rehm LID system gives our customers the chance to expose PERC cells with an individ-
ually controlled laser solution to reduce LID to a minimum. With more than 750 solar units
installed and operated all over the world, Rehm has the experience and insight necessary to
develop equipment and processes to meet the highest requirements.

Highest throughput and best results
Would you like to combine optimal ring solutions and
reliable drying methods in your metallization process? Our
metallization line concept, which consists of the RDS Dryer
with Oxidizer, the Speedre Firing Furnace and the LID
Unit based on customer specication, is an important part
within the production line of solar cells. The Speedre Firing
Systems for the metallization of crystalline silicon solar cells
excel because of the high quality design. The modularity is
the key feature that allows these systems to perfectly t into
any solar cell manufacturing environment. Nowadays more
and more manufacturers tend to consider the huge quality
contribution that the drying process has in the crystalline
silicon solar cell production. Good drying means excellent
adhesion of the printing pastes to the wafer. The RDS Drying
Systems meet these requirements at its best and guarantee
reliable drying results.
