FoilMet®: Resource-efficient, flexible solar cell interconnection through laser micro-cutting
The Fraunhofer Institute for Solar Energy Systems ISE has developed a laser process that allows busbar-free PERC and TOPCon solar cells to be interconnected resource-efficiently and flexibly using an aluminum foil. The FoilMet® technology does not require conductive adhesives or solder and enables a…
