Engineered Conductive Materials LLC, a global supplier of conductive interconnect materials for photovoltaic applications, has introduced the DB-1580 Series Conductive Stringer Attach adhesives for back-contact applications in crystalline silicon solar modules.
The new line of conductive adhesives is designed to make contact from vias or other conductors in the solar cells to the back contact sheet. These adhesives are stress-absorbing to withstand the rigors of thermal cycling and have conductive stability to back contact metallizations during damp heat exposure, the company says.
The conductive adhesives are designed to cure through the encapsulant lamination and cure process. Fast-cure versions are available for co-curing with fast laminating encapsulants.
