Abstract:
"The rising global energy demand is causing a dramatic acceleration of social unrest.
Impact of climate change on the environment due to the combustion of nonrenewable
energy sources is becoming increasingly alarming. To mitigate the dramatic surge of the
global energy crisis and furnishing sustainable, renewable and environment-friendly
energy source hold precedence not only to the scientific community but also to the global
population as a whole. Heat can be considered as a renewable energy source owing to its
pervasive and ineluctable nature. Thermal processes produce >90% of the energy we use,
whereas ~60% of energy is inevitably lost through heat dissipation.1-3 Thus, designing of
efficient thermoelectric (TE) materials will cater to its purpose due to their ability to
convert waste heat to electricity reversibly.1,3,4 Exhaust from domestic heating,
automobiles and industrial produce a large amount of unused waste heat that could be
converted to electricity by using thermoelectric devices."
