Abstract
Die Erfindung betrifft ein Verfahren zur Herstellung monokristalliner Solarzellen mit rückseitiger Kontakt Struktur sowie einer im Waferverbund vorliegenden Vielzahl von annähernd flächengleichen Teilzellendioden mit lokalen pn-Übergängen, welche zum Erhalt einer erhöhten Ausgangsspannung in Serie geschaltet werden, wobei zwischen benachbarten Teilzellendioden in einem streifenförmigen Bereich (34), der ohne Dotierung verbleiben kann, ein Riss (35) durch den Wafer hindurch erzeugt wird und durch dessen Überbrückung mit gelöteten oder geklebten Metallbändchen (103) eine Verbindung der Teilzellendioden zur Serienschaltung erfolgt. Erfindungsgemäß wird der Wafer nach in an sich bekannter Weise realisierter Zellprozessierung einseitig Stoff schlüssig mit einer Ausdehnungsplatte (100) verbunden. Es erfolgt die Isolierrissausbildung dann von der der Ausdehnungsplatte gegenüberliegenden Waf erseite. Weiterhin wird die Ausdehnungsplatte mit Wafer erhitzt. In den sich ausdehnungsbedingt vergrößernden Riss oder Spalt wird dann ein Isolierstoff zum Erhalt einer dauerhaften elektrischen Isolation eingebracht.
