Scientists led by staff from Germany's Fraunhofer ISE have demonstrated a new laser printing process in pilot production, which could replace silver paste and screen printing in solar cell manufacturing. The system is said to offer much more flexibility in the layout of contact fingers on the cell surface and a wider choice of metallization materials.Germany's Fraunhofer Institute for Solar Energy Systems (ISE) this week unveiled the results of a project exploring alternatives to the screen printing with silver paste currently used to produce the contact fingers on silicon cell surfaces. The ...Den vollständigen Artikel lesen ...
