• Exclusive Epi Agreement and Investment from IQE to move into High Volume Manufacturing of HCPV cells.
• This decision participates to the increase of the use of GaAs substrate for HCPV cells manufacturing, as forecasted in the last Yole’s report on HCPV technology.

This investment and partnership is to scale up Solar Junction’s manufacturing of its world record cell of 43.5% efficiency.

Solar Junction closes its largest round to date of $19.2 mil with investments from New Enterprise Associates (NEA), Advanced Technology Ventures (ATV), Draper Fidher Jurvetson (DFJ) and IQE. With the strategic partnership, Solar Junction is now able to meet demand and fulfill current and future orders with a number of CPV companies. Solar Junction will continue to engage with additional module manufacturers to further technological advances within the CPV market. Solar Junction’s world record efficiency and sustainable efficiency roadmap exceeding 50% within the decade is a key enabler to reduce CPV module costs to meet the U.S. Department of Energy’s $ / 1 watt objective.

Solar Junction is currently manufacturing CPV cells at a multi-point production efficiency advantage over current market leaders.

This is a potentially transformational opportunity. The CPV market has reached an inflection point in terms of cost comparisons with fossil fuels and is promising impressive growth potential,” said Dr. Drew Nelson, CEO of IQE. “A combination of Solar Junction’s core materials IP and technology, together with our own IP and manufacturing capabilities, provides a compelling route to significantly higher cell efficiency and cost effective, high volume production.”

Solar Junction sought a strategic epi partner, and selected IQE due to its proven expertise in high volume epitaxy, its established reputation in the CPV market and IP, complements Solar Junction’s own technology roadmap to higher efficiencies. IQE is investing $5 mil and receives an exclusive multi-year epi wafer supply contract with Solar Junction.
