Solar Junction rises above its own record with 44.1% cell efficiency
Solar Junction has exceeded its old World-Record with recognition 44.1% cell efficiency on IQE’s production qualified wafers.
IQE plc reports that its high-volume, production qualified material has been individually guaranteed as reaching 44.1% cell efficiency by the National Renewable Energy Laboratory (NREL), outdistancing Solar Junctions previous World Record for a standard triple junction CPV cell.
The wafers were made applying IQE’s high-volume MBE devices, were prepared by, a manufacturer of high efficiency multi-junction solar energy cells for the concentrated photovoltaic market (CPV), IQE’s strategic partner Solar Junction Corporation (“Solar Junction”). The classic three-junction solar are said to set a new world record for manufacturing scale CPV wafer technology and prove the upgraded performance over Solar Junction’s previous World Record announced in October 2012.
“Breaking a World Record is a major achievement, but improving on our most recent record using high-volume production equipment produced in conjunction with our manufacturing partner IQE, and Solar Junction’s fabrication line in Sunnyvale, CA, is dramatically more significant. This result is a testament to our close partnership with IQE, Solar Junction’s dilute nitride technology and our exceptional team. We continue to be the benchmark for multi-junction solar cell production efficiency to assist our customers in driving CPV costs down”, Vijit Sabnis, CEO at Solar Junction announced.
“Following our recent announcement of full qualification of our high volume 4 and 6 CPV technology, surpassing Solar Junction’s previous cell efficiency record is a massive achievement”, are the word of Dr. Drew Nelson, IQE Chief Executive
“Improvements in CPV cell efficiencies translate to highly significant overall cost reduction in terms of installation and energy generation in utility scale solar farms. The fact that this has been achieved on production-qualified platforms is a major milestone. Furthermore, the transfer of wafer production to IQE’s manufacturing tools enables the Solar Junction team to focus on further improving efficiencies on lattice-matched, multi-junction CPV solar cells using a combination of their unique dilute nitride technology, combined with pre existing IQE IP. This will facilitate seamless technology transfer into high volume manufacture of ultra efficient CPV cells as the conversion efficiency improves further”, he added.
