Carbon Nanotube ‘Light Funnel’ Could Make Solar Panels More Efficient

published September 13, 2010 and has No Comments

Photo: Patrick Gillooly, MIT What Can't We Do With Carbon Nanotubes? MIT researchers have found a way to use carbon nanotubes to concentrate light by about 100x and funnel photons into smaller (thus less expensive) solar panels. "Instead of having your whole roof be a photovoltaic cell, you could have little spots that were tiny photovoltaic cells, with antennas ...
