DuPont Photovoltaic Solutions introduced new innovations for its DuPont Solamet photovoltaic metallization paste to enable advanced screen printing at the 2017 International Photovoltaic Power Generation Expo in Tokyo, Japan.
Specially designed for double printing, Solamet PVD1x and PVD2x comprise an integrated two-layer solution with excellent compatibility to maximize cell performance. The first layer demonstrates super low contact resistance and excellent fine line printing, while the second layer delivers better electrical conductance and good solderability for high adhesion. This leading solution for double printing enables more than 0.1% efficiency gain.
DuPont also introduced Solamet PVM1x to support the new development of the Mesh-Cross-Free (MCF) screen. Solamet PVM1x has excellent matchability with various MCF parameters, outstanding printability and yield to both multi and mono wafers with 0.1% efficiency gain.
At the Expo, DuPont is collaborating with Taiwan Solar Energy Company (TSEC) to demonstrate the increased efficiency and power output that DuPont Solamet technology can provide. TSEC, which specializes in manufacturing high performance, top quality mono- and polycrystalline silicon solar cells and modules, has observed 21.15% cell efficiency and module power output as high as 305 Watts (60 pcs) in its mono PERC modules.
In addition to spotlighting DuPont Solamet front side silver pastes, the DuPont booth at PV Expo 2017, located at E43-9, will feature DuPont Tedlar PVF film, the only backsheet material vigorously tested in the field for more than 30 years to improve lifelong performance and reliability. DuPont Xavan weed control fabric for ground mounted systems, which helps make system operation and maintenance safer and easier, and DuPont high-performance polymers that enable lighter-weight system installations also will be featured. DuPont experts will discuss the company’s rigorous Module Accelerated Sequential Testing (MAST) procedure, which better determines the long-term performance of systems by simulating real-world conditions and by combining and repeating multiple aging stresses.
DuPont Photovoltaic Solutions (DPVS) is the leading supplier of specialty materials to the solar energy industry. Since 1975 more than half of the world’s 900 million installed solar panels contain DuPont materials. The DPVS portfolio, including Solamet photovoltaic metallization pastes and DuPont Tedlar® polyvinyl fluoride films, is the established benchmark of the industry, delivering lifelong value through proven performance, reliability, efficiency, and best return on investment.
