Ribbon attach conductive adhesive
11 July 2011
Engineered Conductive Materials’ DB-1541-S3 Conductive Stringer Attach adhesive is for use in thin-film, organic and thinned silicon solar modules. This material formulation has been optimised for excellent conductivity and stability on molybdenum substrates while reducing the silver content to reduce cost.
The DB-1541-S3 has more than 12% lower silver loading than the standard DB-1541-S series of conductive stringer attach adhesives, resulting in a significant price reduction while maintaining optimised rheology for dispensing and excellent damp heat resistance and conductivity stability on tin, tin-silver and silver-plated ribbons. Even with the lower silver content, this material has a lower volume resistivity than DB-1541-S.
DB-1541-S3 features a rubber-like flexibility that is ideal for flexible photovoltaic applications with high peel strength to withstand the stresses induced in reel-to-reel manufacturing processes.
This latest addition to Engineered Conductive Materials’ full line of conductive stringer attach adhesives can also be used for conductive adhesives for back contact crystalline silicon, thin-film and via fill applications, as well as conductive grid inks for photovoltaic applications.
