New paste raises solar cell conversion efficiency and delivers greater performance.
TAIPEI CITY, TAIWAN- October 12, 2016- Heraeus Photovoltaics, the worldwide leading supplier of metallization solutions to the PV industry, announced the introduction of a new generation of high efficiency silver front-side metallization paste at the PV Taiwan International Photovoltaic Exhibition.
The new Heraeus SOL9641A series front-side silver paste raises the conversion efficiency of solar cells by 0.1%. It shows superior adhesion for PERC cell and is compatible for both multi and mono crystalline wafers. The excellent adhesion of SOL9641A allows customers to optimize their busbar design for better electrical performance and cost reduction, especially on black-silicon texturings.
Its ultra-fine line screen printing capabilities make the 9641A perfectly suitable for the latest screen technology with narrower finger opening, high mesh and thinner wire as well as for knot-free screens. The SOL9641A incorporates an innovative organic system which enhances printability in high-through- put mass production with improved finger geometry. Such benefits have been testified by customers with better efficiency and higher production yield. An additional key feature of the 9641 is the wide processing window of 50°C with an optimal firing window toward lower temperature range, which is beneficial for PERC-solar cells.
