(GIST OF SCIENCE REPORTER) New material found can efficiently convert waste heat to electricity to power
Scientists have found a new Lead (Pb) free material which can efficiently convert waste heat to power our small home equipment and automobiles.
Thermoelectric energy conversion allows generation of electrical voltage when one end of a material is heated while keeping the other side cold. Finding an efficient material to realize this scientific principle has been a daunting task for scientists. It entails fitting in three seemingly different properties into a single material-- high electrical conductivity of metals, high thermoelectric sensitivity of semiconductors, and low thermal conductivity of glasses.
Most efficient thermoelectric materials developed by scientists so far use Lead (Pb) as a major constituent element, restricting their use for mass-market applications.
