Spire to Develop 42% Efficient CPV Cells

Spire Corporation announced that its wholly owned subsidiary, Spire Semiconductor LLC, has been awarded a US $3.7 million, 18-month program contract by the Department of Energy’s National Renewable Energy Laboratory (NREL).

The award from NREL consists of $2.96 million in government funding and a $745,509 cost share. Under the contract, Spire Semiconductor will develop next-generation manufacturing technology to produce 42% efficient III-V three junction tandem concentrating solar photovoltaic (CPV) cells.

“Spire has been involved in the solar energy market for over 25 years. Development of this cell will put us in an excellent position to capitalize on the growing market opportunity for custom gallium arsenide (GaAs) based solar cells for Concentrator Photovoltaic (CPV) systems. Our Spire Semiconductor facility has state-of-the-art capabilities for producing these devices. We plan to offer our new series of triple junction ‘Triathlon’ concentrator solar cells to system integrators around the world,” said Roger Little, chairman and CEO of Spire Corporation.
