The panoscopicapproach to high performance thermoelectrics
Introduction
Thermoelectric (TE) technology is basedon the energy conversion interplay between heat (temperature gradient,more precisely)and electricity,which can lead to power generation and cooling.The prospectof widespread solid-state thermoelectric devices with no moving parts,goodreliability and scalability has aroused worldwide interest in waste heat recoveryand solar heat utilization as well as temperature control refrigeration.Thekey parameter that defines the efficiency of thermoelectric materials is the‘thermoelectric dimensionless figure of merit’ ZTwhich derives from acombination of three physical properties:1–6 thermal conductivity(k),electrical conductivity (σ) and Seebeck coefficient (S),ZT = (S2σ/k)T,where T is the temperature.The quantity of S2σis defined as the power factor.Therefore,both the electrical conductivity σand Seebeck coefficient S must be large,while the thermalconductivity k must be minimized.This well-known interdependence amongthe physical properties makes it challenging to develop strategies forimproving a material’s average ZT.1–6
Although Seebeck observedthermoelectric phenomena in 1821 and Altenkirch defined the ZT equation in 1911,ittook several decades to develop the first functioning devices in the 1950s and1960s.4 They are now called the firstgeneration thermoelectrics with an average ZT of 1.0,and devices madeof them can operate at 4–6% conversion efficiency.
