Low-cost snap cure conductive adhesive for stringing solar modules

Engineered Materials Systems has unveiled its new EMS 561-403 low-cost snap cure conductive adhesive for stringing applications in crystalline silicon and thin-film solar modules. EMS 561-403 is designed to electrically interconnect solar cells using ribbons. The adhesive is stress absorbing to withstand the rigors of thermal cycling and features high conductive stability to cell and ribbon metallization during damp heat exposure. Additionally, the conductive adhesive is designed to cure in seconds at 180C or above to enable fast fixing of the cells. EMS 561-403 is approximately 50 percent lower cost than standard silver filled conductive adhesives, says the company.
