In a new report in Science, Paul S. Davids and a research team at the Sandia National Laboratory in the U.S., demonstrated the conversion of thermal radiation into electrical power. For this, they used a bipolar grating-coupled complimentary metal-oxide-silicon (CMOS) tunnel diode. Using a two-step photon-assisted tunneling charge pumping mechanism, the team separated the charge carriers in pn junction wells to develop a large, open-circuit voltage across a load. The scientists experimentally showed electrical power generation from a broadband blackbody thermal source with converted power densities of 27 to 61 \u00b5W\/cm2 for thermal sources between 250 degrees C to 400 degrees C. The demonstrated scalable and efficient conversion of radiated waste heat into electrical power can be used to reduce energy consumption\u2014in order to power electronics and sensors.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2020-03-electrical-power-moderate-temperature-radiative-thermal.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Electrical power generation from moderate-temperature radiative thermal sources<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Moderate-temperature thermal sources often radiate waste heat as a by-product of mechanical work, chemical or nuclear reactions, or information processing.
