The Heraeus Photovoltaics Business Unit will be attending PV EXPO to be held at Tokyo Big Sight, Japan, from February 26-28, 2014.

Heraeus will be highlighting their new metallization pastes for conventional and novel cell designs. These pastes have demonstrated improved conversion efficiencies and higher performance at a lower cost per Wp. To discuss Heraeus’ innovative product portfolio and services, visit us at booth E51-14 in hall 4-6.

The products to be highlighted at the show will be the 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 solar cells.

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.

On 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.

New at Heraeus is the SOL9620 Series. Preliminary customer testing 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 90 Omega/sq. and 110 Omega/sq wafers, relative to the best commercially available front-side pastes.
