Solamet® Rearside Low Silver Tabbing Metallization Paste

Low Silver DuPont™ Solamet® Designed to Drive Costs Down for Solar Cell Manufacturers

Low silver Solamet® photovoltaic metallization rear side paste is based on unique chemistry delivers higher cell performance and higher module reliability.

Cost advances to lower LCOE

• Higher adhesion to lower laydown
• Higher adhesion to reduce print footprint
• Silver replacement technology in the future

DuPont™ Solamet® PV51M photovoltaic metallization rear side paste is a highly conductive solderable silver composition, developed to lower consumption yet providing excellent adhesion when used in conjunction with back side aluminum compositions. This paste may be co-fired with front side (n-type) silver conductors such as DuPont™ Solamet® PV15x and Solamet® PV16x, PV17x and with back side (p-type) aluminum conductors such as DuPont™ Solamet® PV3xx.

DuPont™ Solamet® PV51x features include:

• Excellent printability window
• Co-firable with current Solamet® frontside silver pastes
• Superior adhesion window
• Reduced laydown
• Reduced tab footprint
• Lead and Cadmium free*


*Lead and Cadmium ‘free’ as used herein means that Lead or Cadmium are not intentionally added to the referenced product. Trace amounts however may be present.

DuPont™ Solamet® PV52A photovoltaic metallization rear side paste is based on unique chemistry delivering higher cell performance and higher module reliability.

DuPont™ Solamet® PV52A features include: 

• 30% Lower unit consumption per cell
• Enhanced solderability and reliability
• More than 30% paste saving
• Sustained higher power output
• Lead and Cadmium free


* Lead and Cadmium ‘free’ as used herein means that Lead or Cadmium are not intentionally added to the referenced product. Trace amounts however may be present.

Other Tabbing Silver Pastes Include:

Solamet® PV505 & PV506 - A highly conductive silver composition, developed to provide excellent adhesion when used in conjunction with rear side aluminum compositions
