OPV adhesive from ECM cures at low temps

Engineered Conductive Materials introduced the DB-1541-LTC low-temperature-curing conductive adhesive for low-temp processing and high flexibility, suiting OPV and other flexible solar modules.

July 29, 2011 — Photovoltaics (PV) materials supplier Engineered Conductive Materials LLC (ECM) introduced the DB-1541-LTC low-temperature-curing conductive adhesive for organic photovoltaics (OPV) and other temperature-sensitive solar module assembly. The material formulation targets high conductivity and stability on various substrates when cured at 100°C. It can be fast cured at elevated temperatures (1 minute @ 180°C).

The DB-1541-LTC has a dispensing work life greater than 48 hours (measured as a 25% increase in viscosity), while maintaining optimized rheology for dispensing. It offers damp heat resistance and conductivity stability on tin, tin-silver and silver-plated ribbons. The product?s ?rubber-like? flexibility enables flexible photovoltaic applications with high peel strength to withstand the stresses induced in reel-to-reel manufacturing processes.

Engineered Conductive Materials makes conductive stringer attach adhesives and conductive adhesives for back contact crystalline silicon, thin-film and via fill applications, as well as conductive grid inks for photovoltaic applications. For more information, visit www.conductives.com.
