We numerically demonstrate that antennas are able to generate low-power dc signals by beneficing of the thermoelectric properties of the metals that constitute them. We theoretically evaluate the optical-to-electrical conversion efficiency for harvesting applications and finally discuss strategies to increase its performance. Thermocouple optical antennas therefore open the route toward the design of photovoltaic devices.engjournal articlehttp://scitation.aip.org/content/aip/journal/apl/105/9/10.1063/1.4895028open access620.91Infrared detectorNanoantennasAntennasThermoelectric microgeneratorsSolar energyÓptica (Física)2209.19 Óptica Física
