RE: [hreg] Fw: solar Boeing Spectorlab
Bashir, Boeing has always concentrated (no pun intended) on space applications, and at 40% efficient these cells would command a huge premium for space and satellite applications. It would seem to me that they could sell everything they can build for satellites, which is a much more lucrative market than terrestrial applications. I’ll be real curious to see if they actually pursue terrestrial applications instead of their traditional markets, just how much capacity does Spectrolab really have for such specialized cells? And as we all know, getting a new solar technology from lab to production is often a long and expensive path, many of the cells that hold efficiency records are not available commercially, they can be hand built in small quantities but achieving those efficiencies on a megawatt basis is very difficult.

Those of us who attend International Meetings and are familiar with who is doing what in different countries, have known about the Concentrator Cell Technology, in which Fraunhofer Institute for Solar Energy Systems Freiburg, Germany. [Reference: Fraunhofer Institut Solare Energiesysteme, "Annual Report 2004 - Achievements and Results." www.ise.fraunhofer. de ] is quite well known.
Yes, the technology is there but at higher cost compared to Commercial Silicon technology.

There is some duplicationof the info in J.P. Malone's message but maybe
there is some additional info.
Boeing Spectrolab terrestrial solar cell surpasses 40% efficiency
Spectrolab, a wholly owned subsidiary of Boeing, has achieved a new
world record in terrestrial concentrator solar cell efficiency. Using
concentrated sunlight, Spectrolab demonstrated the ability of a
photovoltaic cell to convert 40.7 percent of received solar energy into
The U.S. Department of Energy's National Renewable Energy Laboratory in
Golden, Colo., verified the milestone last month.
"This solar cell performance is the highest efficiency level any
photovoltaic device has ever achieved," said Spectrolab President David
Lillington. "The terrestrial cell we have developed uses the same
technology base as our space-based cells. So, once qualified, they can
be manufactured in very high volumes with minimal impact to production
Spectrolab officials say that high-efficiency multijunction cells have a
significant advantage over conventional silicon cells in concentrator
systems because fewer solar cells are required to achieve the same power
output. This technology is expected to continue to dramatically reduce
the cost of generating electricity from solar energy, as well as the
cost of materials used in high-power space satellites and terrestrial
"These results are particularly encouraging since they were achieved
using a new class of metamorphic semiconductor materials, allowing much
greater freedom in multijunction cell design for optimal conversion of
the solar spectrum," said Spectrolab's Richard King, principal
investigator of the high-efficiency solar cell research and development
effort. "The excellent performance of these materials hints at still
higher efficiency in future solar cells."
Spectrolab is reducing the cost of solar cell production through
research investments and is working with several domestic and
international solar concentrator manufacturers on clean, renewable solar
energy solutions. Currently, Spectrolab's terrestrial concentrator cells
are generating power in a 33-kilowatt full-scale concentrator system in
the Australian desert. The company recently signed multimillion dollar
contracts for its high-efficiency concentrator cells and is anticipating
several new contracts in the next few months.
Development of the high-efficiency concentrator cell technology was
funded by the NREL's High Performance Photovoltaics program and
