Heraeus Photovoltaics introduces SOL9641A series silver front-side metallization paste

Heraeus Photovoltaics has introduced Heraeus SOL9641A series 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%. According to the company new metallization paste comes with superior adhesion for PERC cell and is compatible for both multi and mono crystalline wafers.

SOL9641A allows customers to optimize their busbar design for better electrical performance and cost reduction, especially on black-silicon texturing. 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.

Heraeus notes that SOL9641A incorporates an innovative organic system which enhances printability in high-through-put mass production with improved finger geometry. 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.

Weiming Zhang, Chief Technology Officer of Heraeus Photovoltaics said, “With photovoltaics scientists and engineers working with customers across Taiwan, China, Singapore and the United States, our research and development is literally a 24-hour a day effort. That type of continuous and non-stop collaboration from our global team is one of the main reasons we can get new innovations like the SOL9641A series to market so quickly.”
