Spire Receives Contract for Thermo PV Cells

Bedford, Massachusetts [] Spire Corporation announced that it has received a $600,000 contract from NASA’s John Glenn Research Center in Cleveland, Ohio, to further develop a new type of thermo photovoltaic (TPV) cell that produces electricity using heat from combustion. The work will be carried out in part at Bandwidth Semiconductor, a wholly owned subsidiary of Spire. Bandwidth already offers GaAs concentrator PV cells for converting the sun’s energy to electricity. These TPV cells use InGaAs, a variation of GaAs.
