 Harvesting Solar Energy From Nano-Thin Films

Research for the U.S. Army is focused on applying nanocomposite thin-film PVs. They are constructed from nanoparticles of titanium dioxide with a light-harvesting dye sandwiched  between two plastic based electrodes. The cells are the thickness of three  sheets of paper and can be cut to any length or width. The target is to provide 30 Watts per pound. The BA 5590 battery provides 22 Watts per pound.

The PV cells could be incorporated into devices and shelters, providing continuous daylight power. The flexibility points to forming it into fibers which could then be weaved into textiles. (Ed. note: with PV swimming suits, the term ‘Hot Momma’ could take on new meaning.)

(Sept. 2003) The U.S.  Department of Energy selects entrants for the 2005 Solar Decathlon.  Students from around the globe will converge on the National Mall in Washington, D.C. during the fall of 2005 for a “constructive demonstration” of solar power in the U.S. Department of Energy’s second Solar Decathlon.  The 2005 competition will feature 20 teams, up from 14 entries in the first contest.
