DuPont Solamet PV76x Metallization Pastes Enable REC TwinPeak Solar Panel

Advanced Materials Key to High-efficiency Solar Technology

TAOYUAN, Taiwan October 13, 2015 -- DuPont Microcircuit Materials (DuPont) recently collaborated with REC, a leading global provider of solar energy solutions, on its high-efficiency, award-winning TwinPeak solar panels. The metallization grid of the solar cells powering the TwinPeak solar panels is made using DuPont Solame PV76x photovoltaic metallization paste, an advanced front side silver material designed specifically to enhance Passivated Emitter Rear Cell (PERC) technology that delivers significantly higher solar cell efficiency and results in greater power output for solar panels.

"This achievement is the result of close collaboration in which DuPont and REC have focused on optimizing successive generations of materials and manufacturing technologies so that they work better together," said Thomas Lin, global photovoltaics marketing manager, DuPont Microcircuit Materials. "DuPont continues to innovate with Solamet pastes and bring the latest advanced materials to help improve the power output of solar panels even further. PERC is an exciting technology that Solamet pastes enable, and REC is getting outstanding results."

REC TwinPeak Series solar panels were recently recognized with the highly regarded Intersolar Award, which honors innovative solutions in the solar industry. The panels feature half cut cells, split junction boxes, four bus bars and PERC technology, resulting in higher overall energy yield.

"REC appreciates the collaboration with DuPont and its development of Solamet pastes which enhance the efficiency of our PERC cells," said Ter Soon Kim, senior vice president, Operations and Technology, REC. "The paste is specifically designed for this type of technology and helps to enable our cell production process. This strong collaboration with DuPont continues to improve the power output of REC solar panels and reaffirms our reputation for consistently innovative, high performance products."

DuPont Solamet PV76x paste is the latest in a series of products designed to enable cutting-edge PERC technology. DuPont was the first in the industry to introduce local back surface field aluminum pastes and rear-side tabbing pastes specifically designed for industrial PERC solar cells, with Solamet PV36x series aluminum pastes and Solamet PV56x series rear-side tabbing pastes, respectively. With Solamet PV76x series front side silver pastes, DuPont was also the first in the industry to develop front side silver pastes specifically for PERC technology. DuPont Solamet integrated metallization solutions for PERC have been demonstrated in production to deliver more than 0.15 percent significant efficiency gains for both multi- and mono-crystalline silicon PERC solar cells.
