High throughput and high precision can help reduce solar cell production costs. A research group at Fraunhofer ISE has made progress with a laser system to process wafers for metallization. The system reportedly works 10 to 20 times faster.From pv magazine Germany With a new type of laser, wafers can be processed 10 to 20 times faster than before. This is the result of a research project at the Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) in Germany. The researchers developed a prototype that can engrave the finest structures in silicon wafers using UV waves. The new system concept ...Den vollständigen Artikel lesen ...
