Who recently designed and developed thermoelectric modules using lead telluride (PbTe)?
A. DRDO
B. ARCI
C. ISRO
D. IIT-Delhi
Explanation:
Scientists have developed a new low-cost electrical contact material for thermoelectric devices that is stable at high temperature and can generate electricity by using a temperature difference between its two sides. Researchers from the International Advanced Research Centre for Powder Metallurgy & New Materials (ARCI), an autonomous institute of the Department of Science & Technology, GoI, have designed and developed thermoelectric modules using lead telluride (PbTe) and magnesium stannite silicide (Mg2Si1-xSnx) compounds, which gives more than 10% conversion efficiency.
