SolarSummary: April 15 -21, 2003

by Kirsten Elder Companies in the news APS AstroPower ICP Global Technologies Kyocera PowerLight Shell Solar Systems Design & Technology, LLC Emerging Technologies According to a paper published in the latest issue of Semiconductor Science & Technology, the Hahn Meitner Institute in Berlin has designed an ultra thin solar cell that uses cheaper semiconductor materials than conventional solar cells, and is up to 50 times more efficient. The trick, German physicist Rolf Koenenkamp told edie, is to find a design that can combine a cheap absorber with a cheap substrate. Typical cells that use planar substrates require expensive absorbing materials, so the German team devised an alternative substrate that could be used with cheaper absorbers, while also redesigning the shape of the absorber. The result was a cell with a layer of light-sensitive cadmium telluride (CdTe) placed on top of a layer of porous titanium dioxide. The goal for Koenenkamp is to come up with a cheap, undeveloped absorber that has previously been rejected for its poor performance in a conventional cell. (Edie news, 18/04/03)New Products Kyocera Corporation has announced the introduction of two types of residential solar power generation systems to the Japanese market. Kyocera will release the Samurai, […]
