There are solar panels that generate electricity and those that absorb heat for hot water. And now researchers at MIT and elsewhere say they've made progress on using the sun's heat to make electricity. In a paper published in Nature, the researchers describe the progress they've made on a nanostructured material that improves on the heat-to-electricity conversion rate over existing thermoelectric devices.
Massachusetts Institute of Technology professor Gang Chen said a thermoelectric generator in the shape of a flat plate could be placed inside a glass vacuum tube and covered with a black plate of copper to absorb heat. The other side of the thermoelectric device is exposed to the ambient air, creating a temperature difference on the two sides of the plate, which will induce a flow of electricity.
