Rectannas : Will They Make Solar Cells Obsolete?

Professor Baratunda Cola and colleagues at the Georgia Institute of Technology, Atlanta, claims to have improved on the solar cells available. They have reported their findings in Nature Nanotechnology. The new type of solar cell is actually a rectenna – half antenna and half rectifier that can be tuned to any frequency as a detector, while generating electricity from solar and infrared light falling on it. The team claims they can achieve a broad-spectrum efficiency of 40 percent with their Read more [...]
