Conductive Silver Paste for PV Cell Manufacturers

Targray supplies front and rear-side conductive silver paste (Ag paste) materials developed to provide better yields and higher outputs for solar PV cell manufacturers. The paste compositions are a series of screen printable front and back side silver conductors for monocrystalline and multicrystalline 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 Targray silver pastes are co-fireable with commercial back side Ag and Al conductive paste solutions.

We work closely with suppliers to ensure our silver (Ag) metallization pastes can be customized in accordance with your Solar PV manufacturing process, in order to increase efficiency and fill factor while providing a wider processing window.

Front-side Silver (Ag) Paste

Targray front-side Ag Paste is ideal for lightly-doped emitter designs. Optimized for high throughput processing, our conductive silver paste delivers exceptional aspect ratios and fine line resolution. This highly conductive paste material works effectively in reaction with SiNx and delivers efficiency gains of approximately 0.2%.

 

  • High adhesion capacity (> 3N/mm)
  • High soldering capacity
  • High compatibility with Si-wafer
  • High quality printing capability
  • High compatibility with Aluminum paste
  • Captures higher efficiency and wider processing window.
  • Achieves a higher aspect ratio.
  • Offers low contact resistance on lightly doped emitter.
  • Applicable to a wide range of sheet emitter wafers
  • Customization of the paste is an available option
  • RoHS compliant and Pb free

Rear-side Silver (Ag) Paste

Designed in synergy with Rear-Al paste and Front-Ag paste, our new lead-free conductive rear-side Silver Paste significantly lowers material consumption in solar PV cell manufacturing. It delivers best-in-class soldering capacity with ribbon – higher than other commercially available products on the market today.

 

  • High adhesion capacity (> 3N/mm)
  • High soldering capacity
  • High compatibility with Si-wafer
  • High quality printing capability
  • Co-firable with back Aluminum and front Silver pastes.
  • Increased paste coverage with superior results provides a high quality, cost effective solution.
  • Customization of the paste is an available option
  • RoHS compliant and Pb free
