Directory about solar photoantennas.

Photoantennas are antennas that work in the infrared and visible light range. Solar photoantennas are devices that convert sunlight into electricity. Using antennas instead of the photoelectric effect would allow very high efficiencies and lower costs than competing technologies. Currently (2013) the technology is between proof of concept and working prototype.

: "This new technology could get us over the hump and make solar energy cost-competitive with fossil fuels." -- reference from Solar Rectenna by Brian Willis

Its 70% efficiency in converting light to electricity from the whole solar spectrum breaks the conventional Shockley–Queisser limit by not relying on the same mechanism as classical solar cells. It's cheap, simple and scalable for mass production. (PESWiki March 8, 2013)
