Heraeus Photovoltaics Business Unit will be showcasing its new high-performance metallization paste, SOL9600 at EU PVSEC in Frankfurt next week. The new paste was developed to offer significant improvements in contact quality on regular and high sheet emitter wafers that have resulted in as much as a 35% reduction in contact resistance. This results in a higher fill factor, boosting efficiencies.
Overall efficiency gains are claimed to be as much as 0.3%, compared to previous pastes such as SOL9235 and SOL9411.
“This series of pastes introduces significant improvements over current industry applications and is further indication of Heraeus' leadership in the PV pastes arena,” noted Andy London, Global Manager of the Photovoltaics Business Unit at Heraeus.
Heraeus said that the new metallization paste, delivers finer line resolution printing and higher efficiencies while maintaining a broad process window during the firing step, enabling tighter production output distribution and improved yields.
