Heraeus - Model SOL9620 Series -Highest Efficiency Pastes with Industry Leading Stability

Heraeus continues to assist cell manufacturers to improve the output of conventional solar cells with the introduction of our SOL9620 Series of metallization pastes. Several major cell manufactures have confirmed higher cell efficiencies relative to the best commercially available front-side pastes. Their improvements ranged between 0.05% and 0.20% absolute on 90Ω/sq. wafers, with even greater gains on 110Ω/sq. wafers, depending on their process and reference paste. Heraeus’ SOL9620 Series is able to contact lowly doped and ultra lowly doped emitter wafers, and possesses unique characteristics for high value cell production. The SOL9620 Series displays the highest long-term cell efficiency stability. Also, the SOL9620 Series has a lower peak temperature firing requirement relative to the SOL9610 Series. This lower temperature characteristic is ideal for both PERC and n-Type cell design applications.
