According to the Australian National University (ANU) website, the university and the University of California, Berkeley, have developed a unique property of nano-metamaterials that emit light in unusual ways when heated. This result is expected to promote the revolution in the solar cell industry, bring thermal photovoltaic cells that convert radiant heat into electricity, and collect heat in the dark to generate electricity. Sergey Kruck of the ANU Institute of Physics and Engineering says the new metamaterials overcome some of the technical hurdles that can open the potential for thermal photovoltaic cells and are expected to make them twice as efficient as conventional solar cells . Thermal photovoltaic cells generate electricity that does not require direct sunlight but instead collects the heat in the form of infrared radiation from the surrounding environment. They can recycle the heat radiated by the engine or combine it with the burner to generate electricity on demand. The new metamaterial has a nano-scale microstructure composed of gold and magnesium fluoride that emits radiation in a specific direction and also changes shape to give a special light, whereas conventional materials can only heat in the full range of infrared light waves. Therefore, using this material to make lasers matching thermal photovoltaic cells is ideal. Researcher Sergey Crook and material structure diagram The extraordinary performance of the material from its novel physical properties, its magnetic hyperbolic distribution, said the electromagnetic radiation in different directions. Natural materials such as glass or crystal, the shape of the radiation is a simple spherical or ellipsoid, and metamaterial radiation in a completely different form, which is due to the material and the magneto-optical element has a strong interaction. Crook predicts these surprising properties of new materials, and his team, working with the University of California, Berkeley, who specializes in making such materials, uses cutting-edge technology to make such materials, which make up less than the basic unit of material 12,000th of hair cross section The researchers said that if the emitter and receiver spacing can reach the nano-scale, with this meta-material-based thermal photovoltaic cells made of the efficiency can be further improved. In this configuration, radiant heat is transferred between the two more efficiently than conventional materials by a factor of 10. Related papers published in the recent "Nature Newsletter" magazine. Chief editor punctuality Special film of waste heat for the light, the light is electricity, if really cost-effective, we retreat in the mountains, 徜 徉 sea, you do not need a diesel generator. As long as the body is still warm, the phone will not worry about no electricity. But then again, much of the innovative material in the Optoelectronics Kingdom, such as the screws on a car, can not be used without reference to the cheap material.
