Manzs Solar cSi division, based in Reutlingen, Germany, chose to integrate Rehms RFS-D 500 Fast-Firing System following an extensive market research and product evaluation process.
Now in widespread use around the world, Rehms popular RFS-D 500 Fast-Firing System features a wide range of innovative design features to enable new levels of metallization process performance. Delivering a large process window thanks to flexible temperature profiling, the system is ideal for the production of highly efficient solar cells. Manz also added a Rehm Thermal Oxidiser with a combustion temperature of 750°C to the RFS-D 500 system, ensuring 99.9 percent exhaust gas incineration to safeguard productivity even further.
Commenting on the selection, Rehm General Manager, Johannes Rehm, explains: Were delighted that such a respected provider of integrated production lines for crystalline silicon solar cells and thin film solar modules has selected our Fast-Firing System.
Having worked closely with the Manz team throughout its extensive evaluation process, we know the reasons they decided on our system were a mixture of our renowned worldwide after-sales service, short response times and capacity to deliver a German development team.
Of course, the RFS Systems ability to lower the total cost of ownership through minimal energy and media usage, short maintenance times, small footprint and attractive price-point, naturally appealed to the team, too!
Evaluation proved that our system delivered the best cell result with regard to bulk factor and efficiency, the lowest cell breakage rate at less than 0.25% and high machine availability at 95 percent uptime. Advanced technologies such as intake air preheating and a VOC thermal oxidiser with 99.9 percent efficiency were also extremely compelling for Manz. In short, there were so many reasons to choose Rehm and we look forward to a highly successful partnership!
Rehm RFS-D 500 is a dual lane fast-firing system with integrated Rehm RDS HT high temperature dryer featuring a 440 mm/optional 500 mm belt in the integrated Manz 60 MV peak cSi line.
Positioned behind the Manz printer responsible for the application of front-side fingerprint with silver sintering paste, the system allows the paste to be dried before being sintered in the systems burn out area at a maximum temperature of 600°C, along with the aluminium prints which have been dried in the pre-processors on the back sides along with the printed/dried busbars. The interlayer connection on the cell is made in a matter of seconds in the fast-firing area at a temperature of 750°C to 1000°C.
