Thermoelectric Heat Conversion Increased Ten Percent

• arclein
n alloy of lead telluride (PbTe), for example, which has long been used to generate electricity aboard satellites, has a ZT of around 0.8. Researchers have now made one of the most common thermoelectric materials more efficient with a ZT of 1.8. A ZT of 1.8 at 850K has a energy conversion efficiency of about 20 to 22% instead of 13 % at ZT of 0.
