Sun-Free Photovoltaics Open New Perspectives in Nano-Technology
31 July 2011 | Solar Power | No Comments
Have you ever imagined a photovoltaic system that produces electricity without sunlight? Even it’s hard to believe, MIT researchers developed such a photovoltaic system that can run only on heat. Using any source of heat, this system will be able to generate electricity, giving the necessary boost to the future of renewable energy.
On its surface, this photovoltaic system has billions of tiny nano-pits that can convert heat into precise wavelengths of light. The produced light enables the photovoltaic system to generate electricity from it.
