DuPont microcircuit materials has said that its ‘Solamet’ PV18x series metallisation pastes have been instrumental in raising REC Solar’s multicrystalline modules' peak power performance (Pmax(Wp)) to new record levels.
DuPont noted that it had been collaborating with REC Solar on metallisation paste optimisation since operations at REC’s state-of-the-art manufacturing facility in Singapore started in 2010.
REC has previously reported in financial statements that it was focusing on reducing losses due to absorption in front and rear solar cell layers and thereby increasing cell voltage. The focus on front-side cell improvements had contributed to increased cell efficiencies.
The company had reported that average multicrystalline solar cell efficiencies at its Singapore plant had reached 17.1% across all production lines in 2012, up from 16.8% in 2011.
“Constant innovation in Solamet pastes has been instrumental in ensuring the efficiency improvements and cost effective measures that are moving the solar industry toward grid-parity,” said Peter Brenner, global photovoltaics marketing manager, DuPont microcircuit materials. “Collaborations with leading companies like REC are critical to the quick delivery of new and improved technologies that fuel further growth in the industry, and for our customers.”
Although REC Solar has yet to reveal efficiency gains achieved in 2013, DuPont microcircuit materials noted in a statement that its customer had raised the efficiency of its 60 cell multicrystalline panels to 265 Pmax(Wp) - its highest average production level reported. REC Solar’s current module documentation for its ‘Peak Energy’ series solar modules tops out at 260 Pmax(Wp).
Ter Soon Kim, senior vice president, operations and technology, REC said: “REC solar panels now deliver more power per square metre due to several design improvements, including the use of the newest frontside metallisation paste provided by our premier innovation supplier, DuPont.”
The company has also been successful at achieving extremely tight module performance distribution levels, having previously noted that it expected 95% of total module production output in Singapore would be 250W modules and above by the end of 2013, up from 55% in the fourth quarter of 2012.
