On an industrial scale, laser technology plays a key role, as it enables low-cost production of high-quality solar cells. Jonas & Redmann develop and design laser systems for micro material processing – hereby ensuring an extremely cost-effective production process with high process efficiency.
The machine platform Laser Contact Opening (LCO) deals with processing the back surface of solar cells using IR lasers in either an “on-the-fly” process or clocked in inline procedure.
The system reliably processes customized patterns as DXF. files or accesses libraries in the laser control. The laser can be flexibly configured to meet specific requirements. This makes it possible to easily optimize processes in order to achieve the maximum efficiency possible.
