Abstract
This disclosure relates to electroconductive paste formulations useful in solar panel technology. In one aspect, the disclosure relates to an inorganic reaction system for use in electroconductive paste compositions, wherein the inorganic reaction system comprises a lead containing matrix composition and a tellurium containing matrix composition. In another aspect, the disclosure relates to an electroconductive paste composition comprising a conductive metal component, an inorganic reaction system and an organic vehicle. Another aspect of the disclosure relates to a solar cell produced by applying an electroconductive paste composition of the invention to a silicon wafer. Yet another aspect relates to a solar cell module assembled using solar cells produced by applying an electroconductive paste composition to a silicon wafer, wherein the electroconductive paste composition comprises an conductive metal component, an inorganic reaction system and an organic vehicle.
