Silver Paste for Crystalline Solar CellsSilver paste conductors optimized for use in solar cell manufacturing
Targray silver paste was developed to provide better yields and higher outputs for solar cell manufacturers. The paste compositions are a series of screen printable front and back side silver conductors for crystalline solar cells. Our compositions are all cadmium-free and tailored solutions for either SiNx or TiOx anti-reflective coatings. Lead-free formulations are also available. All Silver Pastes are co-fireable with commercial back side Ag/Al Pastes.
Targray front side Ag Pastes are ideal for lightly-doped emitter designs and optimized for high throughput processing to deliver excellent aspect ratios and fine line resolution. For back side Silver Paste applications, our new lead-free Ag Paste significantly lowers material consumption due to high coverage and excellent initial and soldered age adhesion. These Silver Metallization Pastes are customizable to your process, thus increasing efficiency and fill factor while providing wider processing windows.
