Analysis of solar cells interconnected by electrically conductive
An alternative technique for cell division and interconnection, which is used in shingled PV modules, is to apply an electrically conductive adhesive (ECA) to the front busbar of one divided cell to interconnect it with the rear Ag pads of another cell [7]. The overlap between the front busbar and the rear Ag pad results in a busbar-less structure.
