According to the researchers, infrared heat radiation can be used to generate electricity – even after sunset, and this allowed them to develop a semiconductor device called a radiant heat diode, which can generate electricity from infrared light radiation.
Lead researcher, Associate Professor Ned Ekins-Daukes, said, “Using thermal imaging cameras, we see a lot of radiation at night, but only infrared wavelengths are not visible”. image).
According to Associate Professor Ekins-Daukes, solar energy transmitted to Earth during the day will be reflected back into space with the same energetic radiation as infrared light at night. The radiant heat-radiating diode device will help capture this infrared heat radiation. By emitting infrared light into a colder environment, the heat-radiating diode generates electricity.
Scientist Michael Nielsen, a member of the research team, said that, with knowledge in solar cell design and optimization, and borrowing materials from the current mid-infrared optical sensor community, scientists learn hope soon realize the dream created Solar power At night.
