Oak Ridge National Laboratory and the University of Tennessee, Knoxville have discovered a way to slow phonons, the waves that transport heat. The discovery could improve novel hot-carrier solar cells, which convert sunlight to electricity more efficiently than conventional solar cells by harnessing photogenerated charge carriers before they lose energy to heat. ORNL’s Michael Manley […]

Ohio State University researchers have figured out how to get the spin of electrons to create a current in non-magnetic materials, which is detected as a voltage in a semiconductor producing electrical power. The team is studying the new magnetic effect that converts heat to electricity and has discovered how to amplify it a thousand […]
