A new photovoltaic energy-conversion system can be powered solely by heat, generating electricity with no sunlight at all. While the principle involved is not new, a novel way of engineering the surface of a material to convert heat into precisely tuned wavelengths of light — selected to match the wavelengths that photovoltaic cells can best convert to electricity — makes the new system much more efficient than previous versions.

Sun-free photovoltaics (Nanowerk News) A new photovoltaic energy-conversion system developed at MIT can be powered solely by heat, generating electricity with no sunlight at all. While the principle involved is not new, a novel way Sun-free photovoltaics is a photovoltaics technology which does not require sunlight to produce electricity. This technique was developed by research team at Massachusetts Institute of Technology Photovoltaic cells convert light to electricity most efficiently at used in phovoltaic devices are usually silicon (monocrystalline, polycrystalline or amorphous), gallium arsenide, metal chalcogenides and organometallics. Recently, mesoscopic solar cells have made an impact in mercial markets.
