Spectrolab
Granted Approval To Export Solar Cells To Europe
|
 Spectrolab
has received U.S. government approval to export state-of-the art
solar cells, panels, and arrays to major European spacecraft
manufacturers. Solar arrays on spacecraft built by Dornier
Satellitensystem GmbH (a DaimlerChrysler Company), Alcatel Space
Industries, Alenia Aerospazio, and Matra Marconi Systems may now
use Spectrolab's high-power solar cells. Spectrolab's existing
U.S. customers include Space Systems Loral, TRW, Orbital Sciences
Corporation, Ball Aerospace & Technologies Group, Lockheed
Martin, Spectrum Astro, Boeing, and Hughes Space and
Communications Company. Spectrolab's multi-junction gallium
arsenide solar cells can boost on-orbit power capacities to meet
increasing market demands for ever higher revenue-generating
spacecraft. In 1999, Spectrolab delivered solar cells with an
average conversion efficiency of 24.5 percent; next-generation
cells reaching 27 percent efficiencies are now available. The
added efficiency makes it possible to have either a lighter,
smaller array of equivalent power or a more powerful array with no
increase in size or mass. Improved efficiency means a reduction in
launch and on-orbit operational costs. Spectrolab has boosted its
solar cell production capacity to deliver nearly 1 megawatt of
power per year to spacecraft manufacturers, while reducing the
cycle time required to transfer new designs into flight production
by nearly 50 percent. Spectrolab is included as part of Boeing’s
announced acquisition of Hughes.
