Novel thermoelectric nanoantenna design for use in solar energy harvesting
In an article published in the SPIE Journal of Nanophotonics (JNP), researchers from a collaboration of three labs in Mexico demonstrate an innovative nanodevice for harvesting solar energy. The paper, "Thermoelectric efficiency optimization of nanoantennas for solar energy harvesting," reports that evolutive dipole nanoantennas (EDNs) generate a thermoelectric voltage three times larger than the classic dipole nanoantenna (CDN).
