Advances in the conversion efficiency of thermoelectric materials

Green Car Congress

A collaboration including researchers from Boston College, MIT, the University of Virginia and Clemson University have achieved a peak ZT (thermoelectric figure of merit) of 0.8 for the materials and possibly good enough for consideration for waste heat recovery in automotive exhaust systems.
