The Heraeus Photovoltaics Business Unit will be exhibiting at this year's EU PVSEC, to be held in Paris from October 1-3 (EU PVSEC Conference: September 30 – October 4) and will showcase their new metallization pastes for n-type solar cells.
Heraeus provides their customers with the complete family of pastes for the metallization of bifacial n-type solar cells. The new SOL9350 Series for p+ wafer surfaces has recently been introduced to the market. The pastes enable increased cell efficiency and improved printability.
"The SOL9350 Series represents the latest generation of Ag-Al conductor pastes for contacting boron emitters for high-efficiency n-type solar cells. As a result of innovative R&D work, Heraeus pushes the performance of n-type solar cells to the next level with this series of pastes," stated Carsten Mohr, Manager Europe of the Heraeus Photovoltaics Business Unit. "Positive feedback from customers confirms superior processing and significant performance improvements," he continues to say.
Processing improvements include excellent flooding and low bleeding for easier handling. The performance improvements of the paste in turn help to print finger lines with improved line uniformity and aspect ratio. "Cell manufacturers value the ability of the SOL9350 Series to print through narrower finger line openings and providing high line uniformity. This in conjunction with lower contact resistances and minimized cell damaging, this new generation of pastes enables the highest performance for high-efficiency n-type solar cells," explains Dr. Weiming Zhang, Vice President of Technology at the Photovoltaics Business Unit.
The Heraeus Photovoltaics Business Unit offers the complete package of pastes for bifacial n-type solar cells: for p+ wafer surfaces as well as for n+ surfaces. Their current recommendations for n-type solar cells are the Ag-Al conductor SOL9350 Series for p+ emitter in conjunction with the Ag conductor SOL9610 Series or lower Ag content SOL9300 Series for the Back Surface Field (BSF). Driven by innovation, the Heraeus R&D team is constantly working on the development of new metallization pastes for n-type solar cells.
