Solar Junction slams its own record with 44% efficiency

The company has broken its own world record with its latest III-V multi-junction solar cell

Silicon Valley based solar energy company Solar Junction has set a world record for energy efficiency of a commercial-ready production solar cell.

"Breaking our own world record cements Solar Junction as an innovator and leader in the multi-junction cell space," says Vijit Sabnis, VP Technology at Solar Junction. "We continue to push technological boundaries to further drive CPV costs down."

The power conversion efficiency of Solar Junction's cells was measured at 44 percent at 947 suns, beating the company's record of 43.5 percent at 418 suns it set in April 2011.

Both records were verified by the National Renewable Energy Laboratory (NREL).

Solar Junction's new record demonstrates the value of its A-SLAM materials, which provides CPV system manufacturers the foundation to deliver the most efficient conversion of solar to electrical energy.

The firm's CPV panels work by concentrating sunlight onto small multi-junction cells, which Solar Junction manufactures at its San Jose facility.

Solar Junction's announcement falls on the heels of a successful investment round, a 5-megawatt order, and several industry awards.

Earlier this year, Solar Junction and IQE, a global supplier of epitaxial wafers, signed an investment and manufacturing agreement to ramp Solar Junction's SJ3 solar cell product to high volumes.

What's more, Solar Junction is commissioning a 6" production fabrication facility, partially funded by a U.S. Department of Energy SUNPATH contract, in Silicon Valley.

Shipments will begin in the first quarter of 2013.

Solar Junction is a manufacturer of high efficiency III-V multi-junction solar cells based on A-SLAM materials.

Founded in 2007, Solar Junction is headquartered in San Jose, California. Investors include New Enterprise Associates, Draper Fisher Jurvetson, Advanced Technology Ventures, and IQE.
