"As of now, we know that there will be a substantial investment in engineering another breakthrough in carbon nanotube optical rectenna science."
TEHRAN (FNA)- Using nanometer-scale components, researchers demonstrated the first optical rectenna, a device that combines the functions of an antenna and a rectifier diode to convert light directly into DC current.
Based on multiwall carbon nanotubes and tiny rectifiers fabricated onto them, the optical rectennas could provide a new technology for photodetectors that would operate without the need for cooling, energy harvesters that would convert waste heat to electricity -- and ultimately for a new way to efficiently capture solar energy.
