Funneling Solar Energy: Antenna Made of Carbon Nanotubes Could Make Photovoltaic Cells More Efficient
ScienceDaily (Sep. 12, 2010) — Using carbon nanotubes (hollow tubes of carbon atoms), MIT chemical engineers have found a way to concentrate solar energy 100 times more than a regular photovoltaic cell. Such nanotubes could form antennas that capture and focus light energy, potentially allowing much smaller and more powerful solar arrays.
