Engineered Conductive Materials LLC, a supplier of conductive interconnect materials for photovoltaic applications, has launched the DB-1541-LTC low-temperature curing conductive adhesive for use in organic solar modules or other temperature-sensitive photovoltaic devices.
This material formulation has been optimized for conductivity and stability on various substrates when cured at 100 degrees C, according to the company. It also has a dispensing work life greater than 48 hours (measured as a 25% increase in viscosity), while maintaining optimized rheology for dispensing and damp heat resistance and conductivity stability on tin, tin-silver and silver-plated ribbons.
The DB-1541-LTC features a rubber-like flexibility that is ideal for flexible photovoltaic applications and high peel strength to withstand the stresses induced in reel-to-reel manufacturing processes, the company adds. This material also can be fast cured at elevated temperatures (one minute at 180 degrees C).
