New low-cost snap cure conductive adhesive for stringing or shingling solar modules

Engineered Materials Systems has introduced a new EMS 561-676 low-cost snap cure conductive adhesive for stringing or shingling applications in crystalline silicon and thin-film solar modules. The adhesive is designed to electrically interconnect solar cells using ribbons or direct cell-to-cell contact. It is stress-absorbing to withstand the rigours of thermal cycling and features excellent conductive stability to cell and ribbon metallisation during damp heat exposure. Additionally, the conductive adhesive is designed to cure in seconds at 150C to 180C to enable fast fixturing of the cells in the stringer. It offers a cost saving exceeding 50 percent compared to standard silver-filled conductive adhesives.
