New thermoelectric nano-antenna can collect solar energy

The use of nano-devices to capture visible and infrared radiation is an important aspect of collecting solar energy. A few days ago, Mexican scientists showed a new type of thermoelectric nano-antenna for collecting solar energy in the journal Nanophotonics, which generates a thermoelectric voltage three times larger than the classic dipole nano-antenna.

According to reports, the nano-antenna is bimetallic, using nickel and platinum, and produced using electron beam lithography. When researchers compare their thermoelectric voltage with classic dipole nano-antennas, the efficiency of nano-antennas is 1.3 times that of traditional ones. In addition, the new thermoelectric nano-antenna array is also a good choice for collecting waste heat energy, which can be used in many fields such as energy collection from waste heat, sensing and solar thermal energy collection.
