Researchers predict the optical rectina, which converts light to direct current, could be a game changer.

Using nanometer-scale components, researchers have demonstrated the first optical rectenna, a device that combines the functions of an antenna and a rectifier diode to convert light directly into direct current electricity.

Based on multiwall carbon nanotubes and tiny rectifiers fabricated onto them, optical rectennas could provide a new technology for photodetectors that would operate without the need for cooling and energy harvesters that would convert waste heat to electricity. The technology also could ultimately result in a new way to efficiently capture solar energy.

Pacific Energy Solutions LLC, Boca Raton, Florida, is being awarded $334,135,534 for firm-fixed-price task order 0002 under a previously awarded solar power generation multiple award contract (N62742-11-D-1192) for the procurement of electricity produced from renewable energy generation systems. The work to be performed provides for purchase of reliable locally generated, alternating current, power from solar power generation systems that are designed, constructed, owned, operated and maintained by the contractor on government property. The government will procure the power using the 10 USC §2922(a) authority.
