New solar cell is not simply collects the energy, but also sends its surplus back into space

Solar panels have been used almost anywhere: from home appliances and to the space station. However, this technology has room to grow. According to the publication ScienceAlert, a group of researchers from the United States and China jointly designed and built a solar panel of a new type. It does not just convert the energy of sunlight into electricity, but also sends the excess heat back into space.

New solar cell is not simply collects the energy, but also sends its surplus back into space

for the development are scientists from Stanford University and their colleagues from the Southeastern University. According to the authors, the basis of the device is radiative cooling principle. In general terms, the essence of the method can be described as the ability of any objects radiate excess heat in the form of infrared light.

"We built the first device that can both produce energy and to save it." - stated the authors of the work.

The new invention is essentially a hybrid technology that can combine the solar panel and the cooling device. Sheer solar panel in this case

It is located under the round radiation cooler consisting of silicon nitride, silicon, and pure aluminum layers located in vacuo.

The basic idea is that the solar panel is transparent and permeable to infrared radiation absorbing so much of the sunlight, excess heat in the form of infrared radiation reflected from the lower layer, "goes back" and is radiated back into space. Themselves, researchers say that their development is aimed not only at improving solar cells, but also to ensure that a positive impact on the environment.

"A great amount of heat coming from the sun just stays in the atmosphere of our planet, that one way or another raises its temperature. Think about the atmosphere as a large blanket around the Earth. This blanket prevents heat easily go from the Earth to the cold universe. But it has a blanket and a "hole" through which heat can be transmitted back into space. "- said in an interview with Chen Zhen, a Chinese professor of Southeast University.
