DuPont Introduces Solamet PVD1x, PVD2x and PVM1x Metallization Pastes for Advanced Screen Printing

DuPont Solamet PVD1x and PVD2x metallization pastes designed for double printing comprise an integrated two-layer solution with excellent compatibility to maximize cell performance.

DuPont Photovoltaic Solutions introduced Solamet photovoltaic metallization pastes for advanced screen printing at the 2017 International Photovoltaic Power Generation Expo in Tokyo, Japan.

DuPont Solamet PVD1x and PVD2x metallization pastes designed for double printing 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.  According to the company this solution for double printing enables more than 0.1 percent 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 percent efficiency gain.

“DuPont is proud to be a leader in the photovoltaic industry by pioneering more than 130 innovations in Solamet^® that consistently enable our customers to improve power output and reduce total system installation costs,” said Daniel LeCloux, global technology manager, DuPont Photovoltaic & Advanced Materials. “We continuously develop metallization materials to enable novel cell technologies.”

At the Expo, DuPont collaborated with Taiwan Solar Energy Company (TSEC) to demonstrate the increased efficiency and power output that DuPont Solamet technology can provide. TSEC has observed 21.15 percent cell efficiency and module power output as high as 305 Watts (60 pcs) in its mono PERC modules.

“DuPont continues to deliver technology advancements that enable module manufacturers to improve their product offerings,” said C.J. Hung, president of Taiwan Solar Energy Company.  “We have come to count on the ability of DuPont to constantly push the boundaries of photovoltaic materials that enable solar products to be more efficient, reliable and offer a higher return on investment.”

In addition to spotlighting DuPont Solamet front side silver pastes, the DuPont booth at PV Expo 2017, also showcased DuPont Tedlar PVF film, the 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 were also featured.
