Conversion of thermal energy into electrical energy.
Technology is in the process of development!
The film of aligned carbon nanotubes can convert infrared radiation of average wavelength range (3-8 µm) in narrow-band photons in the visible range with an efficiency of up to 80 %, and the last with the help of solar cells into electrical energy.
Scientists have created a film of aligned carbon nanotubes, which converts the infrared radiation of average wavelength range (3-8 µm) in narrow-band photons in the visible range and the latter at the expense of the solar cells can be converted into electrical energy.
Film is a channel of carbon nanotubes. In this film “works” in one direction. This is due to the fact that the electrons in nanotubes can only move in one direction. Due to this property of carbon nanotubes infrared photons fall on the film from any direction, and released only one – the back side of the channels.
The theoretical efficiency of converting infrared radiation into visible light, according to scientists, is 80 %. It is estimated that if you integrate this material in solar panels, their efficiency will increase by 22 %.
