Interconnection concepts considered within this work: (A) Tape Solution concept: Adhesive stripes with embedded Cu wires coated with a low-temperature solder alloy are applied on the front and rear solar cells to interconnect the strings (Source: Sticky Solar Power AB); (B) ECA interconnection: ribbons are glued to the cell surface via temperature activating electrically conductive adhesive; (C) Smart Wire Connection Technology: Interconnection via multiple wires coated with low-temperature solder alloy and fixed on a single polymer sheet. Analogically to Tape Solution, final interconnection takes place during lamination, where solder alloy melts.
