High Speed Processing on Large Wafers with Newly Developed On-the-Fly Laser Equipment

In order to be able to manufacture more efficient solar modules, the photovoltaic industry is increasingly switching its production to larger wafer formats. Being able to guarantee the production of these solar cells with an edge length of up to 210 millimeters with consistent quality and cycle rate poses new challenges for equipment manufacturers. A research team at the Fraunhofer Institute for Solar Energy System ISE has now succeeded in implementing a novel system concept, whereby large-format solar cells are continually processed as they move at high speed under the laser scanner. The new system for solar cell processing can laser half a million contact openings per second and has an effective throughput of over 15,000 solar wafers per hour. Visitors to LASER World of PHOTONICS 2022 (April 26-29, Messe München) can learn more about the system concept at the Fraunhofer booth 441 in Hall A6.
