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 efciency. For a sustainable handling of the VOC’s, Rehm has developed

a Thermal Oxidizer, operating at a 99,5 % oxidization efciency. 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 prole, 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 Speedre Firing Furnace and the LID

Unit based on customer specication, is an important part

within the production line of solar cells. The Speedre 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.

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 proling

Temperature prole flexibility

Rehm dryers are designed to handle a variety of drying

proles 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 prole.
