Infrared semiconductor device takes advantage of the temperature difference between earth and space to produce electricity even at night.
The international scientific research team showed for the first time that a large amount of electricity can be generated directly in diodes from the coldest place in the universe without sunlight.
The scientist has installed a device in an extremely low temperature space. This device will create a cold energy source by using optoelectronic physics. That's what we used to harness solar energy. This is an infrared semiconductor device. It takes advantage of the temperature difference between Earth and space to produce electricity.

The study is published in the journal Applied Physics Letters. It is considered a potential solution in creating electricity like the sun but in time both day and night. In the study, the scientists explained how their cathode light emitting diode could produce about 64 nanoWatt / m2.
Although it is only a small amount of electricity, it is important evidence for improving the quantum electronic nature of the device. In theory the device can generate nearly 4 Watt / m2 in a negative temperature environment. It's enough for the machines to operate at night. In fact, solar panels in use can generate about 100 to 200 Watt / m2.
