New Fraunhofer Solar Cell Stringer Uses Adhesives For 2% Boost

An R&D team at Fraunhofer ISE has unveiled a new solar cell stringing machine that can boost cell performance 2% by using electrically conductive adhesives to fix solar cells to a foil substrate in a shingled pattern. The process reduces the number of manufacturing steps that soldering a connective ribbon would require, and imparts more efficient cell performance in several incremental ways.
