The Heraeus SOLSeries of front-side silver pastes are screen-printable conductors for crystalline solar cells, especially formulated to provide higher efficiencies, lower contact resistance and wider processing windows. The results are better yields and higher output for cell manufacturers. Heraeus compositions are all cadmium-free and tailored for either SiNx or TiOx anti-reflective coatings. Lead-free formulations are also available. All Heraeus front-side silver pastes are co-fireable with commercial back-side Ag/Al pastes.
