Found a way to improve the efficiency of solar cells by 80%
Today, solar panels are increasingly being used in everyday life. However, this battery has one major drawback. We can say, Achilles' heel. It's warm. The fact that the hotter panel of Sunny become, the greater their efficacy decreases due to heat dissipation elements, and most of the energy. Therefore, many researchers are working hard to get rid of this shortcoming. Someone is trying to create an efficient cooling system, but the doctrine of the United States went the other way. Their research can improve the efficiency of solar panels by 80%.
How to increase the efficiency of solar cells
Scientists at Rice University want to solve the problem rather trivial sosobom - conversion of heat into light, which can then be used to produce electricity. They say their research could eventually lead to the creation of solar panels, which will be four times more effective than any commercially available solar cells today.
Any hot surface emits light in the form of heat radiation, - says Gururaj Naik, assistant professor of electrical and computer engineering at Rice University. The problem is that heat radiation occurs over a wide spectrum, and conversion of light into electricity is only effective when the radiation is in a narrow range.
Study Group came to the idea of using a film of carbon nanotubes to create a "hyperbolic thermal radiator", which can operate at temperatures up to 700 degrees Celsius. The apparatus allows electrons to move only in one direction. Squeezing photons emitted as heat. As a result, light is generated which can then be absorbed by the solar cell.

In other words, there is a narrowing of the thermal radiation range, which ultimately can convert light into heat, which will hereinafter for the production of electricity.
"Squeezing" all the available thermal energy into a small "spectral range", we can turn it into electricity. Theoretically, we can get up to 80% increase in efficiency, as the heat from the sunlight is not scattered, and goes to the production of electricity.
When the new solar panels will be
At the moment, development of scientists is only at the initial stage, but in theory calculations suggest that using the new approach can be significantly uchelichit energy efficiency of solar panels. Dunn study published in the journal ACS Photonics. But scientists themselves in the near future plan to start practical testing of its technology.
