The Heraeus Photovoltaics Business Unit, a developer and manufacturer of silver metallization pastes for the PV industry, will be exhibiting at this year’s International Green Energy Expo in Daegu, South Korea from April 2nd through 4th. Heraeus will be featuring their SOL9350 Series and the SOL325 Series, which are currently commercially available. Also featured will be the Heraeus SOL9620 Series, front-side pastes for conventional and LDE/ULDE solar cells. Our booth is located in hall 1F, booth number A525.

“This will be Heraeus’ fifth time exhibiting at the Green Energy Expo” according to Andreas Liebheit, Global Manager of the Photovoltaics Business Unit.  He continues to state, “This will be an outstanding year for Heraeus.  We will be introducing new products that will lower our customers’ cost per watt through new technologies developed in our strengthened R&D Group.” 

The industry-leading SOL9350 Series, designed for n-type solar cells with p+ wafer surfaces, provides cell manufacturers with improved cell efficiencies and excels through improved printability. For bifacial n-type solar cells, the SOL9350 Series can be used in conjunction with other Heraeus pastes. The SOL325 Series of low activity pastes can be either used as back-side tabbing paste on standard p-type solar cells and on PERC cells, or for printing front-side floating busbars in Dual Printing.

Also featured from Heraeus will be their SOL9620 Series. Early results from alpha customers has demonstrated that the SOL9620 Series enables cell manufacturers to further improve their c-Si cells’ efficiencies at an industry-leading level. This series of pastes for conventional solar cells has shown excellent contact performance on lightly doped emitters (LDE) and ultra-lightly doped emitters (ULDE). By using this new paste, significant efficiency improvements have been achieved on 90Ω/sq. and 110Ω/sq. wafers, relative to the best commercially available front-side pastes.
