Scientists believe to have discovered a much more efficient way to use silicon to convert heat into electricity – for use in a variety of products ranging from cars to portable electronics.
The concept of converting waste heat into electricity isn’t exactly new, but it never really materialized due to efficiency hurdles. Now, scientists from the U.S. Department of Energy’s (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley think they may have found a key increase the conversion efficiency by a factor of 100.
