Flying On Solar Power spacedaily.com * This may have been previously posted, it appears to be old news * Solar cells designed by United Solar were tested on the Russian space station Mir in the 1990s Auburn Hills - May 26, 2003 United Solar Systems Corp based in Auburn Hills Mich has been awarded an $11,503,782 cost plus fixed fee contract for their program designed to advance the state-of-the-art of ultra lightweight, high efficiency, and flexible thin film solar cell technology for the emerging space and airship markets. The research and development work envisaged in this program aims to accomplish four major objectives. United Solar will develop five each to demonstrate the success of the technology. Objectives three and four of the program would be accomplished under options 1 and 2 of the contract respectively. According to US Department of Defense contract announcements $5,849,000 of the funds has been obligated at this time. Further funds will be obligated as individual delivery orders are issued. This work will be complete February 2005. Solicitation began November 2002 and negotiations were completed May 2003. The Air Force Research Laboratory, Wright-Patterson Air Force Base, Ohio, is the contracting activity.

Finding the answer to that question is essential to the advancement of solar cell research and the ability to produce lower-cost electricity from sunlight.

Steve, there have been several schemes to increase the output of solar cells by using concentrators, but all of them need to track the sun, I don't think that this will have much impact on our solar tech. We are more interested in covering roofs with cells that are barely noticed and won't need unsightly tracking devices. Of more interest to me is the third article that you posted about the breakthrough at Ames in preventing the degradation of amorphous cells with aging. I emailed this information to Unisolar when it first came out, and they were very receptive to looking into the matter. We market our cells based on the output after the degradation, and we would gain quite a bit of efficiency if that would be eliminated. Del
