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, which will create a cold energy source by using the optoelectronic physics that we used to harness energy. solar. This is an infrared semiconductor device , taking advantage of the temperature difference between Earth and space to produce electricity.

The study is published in the journal Applied Physics Letters, which is considered a potential solution in generating electricity like the sun but during day and night. In the study, the scientists explained how their cathode light emitting diode could produce about 64 nanoWatt / m 2 .
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 produce nearly 4 Watt / m 2 in a negative temperature environment, enough for the equipment to operate at night. In fact, solar panels in use can generate about 100 to 200 Watt / m 2 .
