Full power for your metallization line
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.

RDS Dryer
Ready for complex pastes
Drying the large variety of ever evolving solar pastes is
ever more challenging in the silicon solar cell production.
Complex pastes for PERC to HJT cell architectures require
a modular drying system which provides a large process
window for the customer.
While maintaining a short footprint, the RDS can process
5300 wafers/hour at speeds of up to 10 m/min. The system
will easily meet any cycle time requirements called for in
this fast-paced market. It is the chosen dryer of one of the
industry’s top print line manufacturer.
Dual heating concept for best proling
Temperature prole flexibility
Rehm dryers are designed to handle a variety of drying
proles from fast ramp up to temperatures of over 300 °C to
a slow increase in temperature for a very stable heat intake
of the cells. The innovative hybrid heat transfer combines
separately controllable IR and convective heating technolo-
gy. This technology provides the customer with a maximum
degree of flexibility when setting up a prole.
› High prole exibility
› Fast temperature ramp-up
› High throughput
› High energy eciency
› Modular design for integration in HJT lines
› Lane pitch capability of 210 mm – 280 mm

VOC Thermal Oxidizer
for a clean process
Drying solar pastes produces up to 30 % of the weight of the printed paste in volatile organic compounds
(VOC). The VOC’s have to be removed from the process chamber via exhaust to avoid contamination of the
process chamber, VOC’s condensation damage on the solar cell and obstruction due to odor development
in the vicinity of the dryer.
The Rehm Thermal Oxidizer will expose the exhaust volume to over 750 °C in order to destroy all VOC’s,
such as alcohols, toluene and terpineol with an efciency of up to 99,9 %. The side products of this process
are water vapor and carbon dioxide and make this a sustainable environmentally friendly process in com-
pliance with legal standards such as the TA Luft, Germany. Even with the higher throughput in modern cell
production, the RehmT hermal Oxidizer can handle the increased VOC content.
