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.
Weiming Zhang, Chief Technology Officer of Heraeus Photovoltaics, noted the newest silver paste innovation is a testament to the company’s global R&D network. He 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.”
The launch of 9641 product marks another milestone by Heraeus to help solar energy companies improve the performance of photovoltaic technology while addressing costs. The company, at the recent SNEC Show earlier this year, publicly stated its belief that renewable energy production costs have the potential to drop as much as 50% every five years, which will help accelerate adoption of solar and other environmentally-friendly energy sources.
Andreas Liebheit, the President Heraeus Photovoltaics, expressed his continued belief that Taiwan remains a critical market force for solar energy development and will play an important role when the market comes back into an upswing mode. “The PV markets across the Taiwan straits are strongly interlinked across the Asia-Pacific region. Taiwan companies have established R&D and production sites in mainland China, so it makes strong strategic sense for Heraeus to have a strong presence in both regions. It allows us to simultaneously work with cell and module manufacturers in both markets to help them deliver even higher-performing cell technologies.”
