The major breakthrough has been reached in the field of opto-electronics where scientists are optimistic of incorporating the technology which can even produce Electric Power at night time.
It is planned to best suite and equip with Solar Panel to get a stable power supply round the clock.
“We were thinking, what if we took one of these devices and put it in a warm area and pointed it at the sky,” says electrical and computer engineer Jeremy Munday, from the University of California, Davis.
The Technology put to test is Radiative Cooling, where the night sky will be considered as a heat sink.
The system will evolve infrared Radiations into the night sky and produce Energy.
It will be following the basic principle of a Heat Engine where the Heat is traded from a Hot Source to a Colder Sink.
And all this boils down to the ability of outer space to behave as a perfect Sink.
Therefore these statements have increased restlessness in the scientific community as it will challenge new boundaries for Energy Production.
“A regular solar cell generates power by absorbing sunlight, which causes a voltage to appear across the device and for current to flow,” says Munday. “In these new devices, light is instead emitted and the current and voltage go in the opposite direction, but you still generate power.”
“You have to use different materials, but the physics is the same.”
However the team estimates that proposed thermoradiative cells would only be able to generate about a quarter as much power as a solar panel of the same area.
That’s mainly a consequence of the lower energy of infrared light.
It may be possible to boost the efficiency of thermoradiative cells by using materials that can better interact with longer wavelengths of light, for example, mercury alloys as compared to the classic sillicon as of Solar Cells.
