Scientists from Stanford University, Shanhui Fan along with Masashi Ono have demonstrated for the first time that it is possible to produce a measurable amount of electricity in an infrared photodiode from the coldness of the universe.The infrared semiconductor uses the temperature difference between Space and Earth to produce the electricity.
- The study was published in a journal named Applied Physics Letters.
- The new device has generated about 64 nano watts per square meter.
- According to the theoretical calculations, the device can generate almost 4 watts per square meter, roughly one million times what practically generated.
- In the new technology, the negative illumination effect allows electrical energy to be harvested as heat leaves a surface.
