The Switzerland-based company says the energy yield breakthrough resulted from the combination of 21% efficient heterojunction solar cells manufactured at group member, Roth & Raus solar technology center under production conditions a very low temperature coefficient of -0.18%/°C, and its SmartWire Connection technology.
The 303 W module is comprised of 60 Cz-Si (Czochralski silicon) pseudo square cells, 156 mm2 in size, with an efficiency of 21%. In a statement released, Meyer Burger says it intends to reach efficiencies of 24% and reduce cell manufacturing costs to under US$0.10/Wp by 2014.
"Further cost reductions can be achieved through the use of thinner wafers which heterojunction technology, in comparison to conventional technologies, can process without any loss of efficiency," continued the statement. It added that a new diamond wire wafer cutting process has been developed to complement Meyer Burgers heterojunction technology.
The new 303 W photovoltaic modules will be displayed at this years EU PVSEC, which is scheduled to kick off tomorrow, September 25 in Frankfurt, Germany.
