comes from Idaho National Laboratory a new form of renewable energy: solar cells that collect energy from the electronic heat the night by doubling the capacity of solar cells during the day.
"The key to these new devices is the ability to collect thanks to an infrared (IR) - Steven Novack says, one of the pioneers of the technology that works at the U.S. Department of Energy, the Idaho National Laboratory in Idaho Falls -. Almost half of the available energy in the solar spectrum lies in the infrared band, and the IR is re-emitted from the Earth after the sun goes down, meaning that antennas can also capture energy during the night. "
This phenomenon, as a sort of ping pong, keeps the band in the infrared on the ground, once freed from the ground, rises to the atmosphere, but the clouds will repel one hand, re-sending it to the ground.
The Novack system is based on some microantenne from 700 nanometers (a nanometer is every millionth of a meter), tuned on the wavelength of infrared and gathering 84%. A revolution that will hopefully soon become a widespread reality.
