FoilMet®: Ressourcenschonende, flexible Solarzellen-Verschaltung durch Laser-Mikrofügen

(PresseBox) (Freiburg, )
Das Fraunhofer-Institut für Solare Energiesysteme ISE hat ein Laserverfahren entwickelt, mit dem Busbarfreie PERC- und TOPCon-Solarzellen durch eine Aluminiumfolie ressourcensparend und flexibel verschaltet werden können. Die FoilMet®- Technologie kommt ohne leitfähigen Klebstoff oder Lot aus und erlaubt eine Reduktion des Silberverbrauchs im Solarmodul um bis zu 30 Prozent. Die mechanisch flexible Verbindung ermöglicht neben einer gekrümmten Auslegung des Strings sowohl eine Anordnung als geschindelte Zellen für maximale Moduleffizienz, als auch das in der Massenproduktion übliche »Nebeneinanderlegen« der Zellen mit geringem Abstand für eine möglichst kosteneffiziente Modulbauweise. Auf der Intersolar Europe (11.-13.5.2022, Messe München, Stand A1.540) zeigt das Institut einen Solarzellenstring zdk 91 Znarnu, bfk fal msl Htwjwkimstuzyv tsemwgpzjet moprn.
