New Material Converts Waste Heat to Electricity for Small Home Appliances & Vehicles

Scientists have found a new Lead (Pb) free material which can efficiently convert waste heat to power our small home equipment and automobiles.

Daily Current Affairs Quiz 2021

Most efficient thermoelectric materials developed by scientists so far use Lead (Pb) as a major constituent element, restricting their use for mass-market applications.

Scientists from Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), Bengaluru, an autonomous institution of the Department of Science & Technology (DST), Government of have now identified a lead-free material called Cadmium (Cd) doped Silver Antimony Telluride (AgSbTe2).

This material which can efficiently allow recovery of electricity from ‘waste heat’ marking a paradigm shift in the thermoelectric puzzle.
