Excellent transverse power generation and cooling performances of artificially tilted thermoelectric film devices

Excellent Thermoelectric Performance from In Situ Reaction between Co Nanoparticles and BiSbTe Flexible Films

“…The black curve is the test data of Co00, and the red one is the test data of Co02, and the blue dotted line is the room-temperature value (Figure ). With the increase in working current, Δ T c increases first and then decreases ,, because of the synergistic effect from Peltier heat, Joule heat, and Fourier heat. When the working current is 0.04 A, the Δ T c of the single-leg device fabricated by Co02 reaches its maximum value (0.5 K), which is 1.5 times higher than that of the Co00 film (0.2 K).…”

Geometrical Optimization and Transverse Thermoelectric Performances of Fe/Bi2Te2.7Se0.3 Artificially Tilted Multilayer Thermoelectric Devices

“…Third, the dependence of V x on the length to height ratio is greatly beneficial in developing the micro/nano-scaled devices. It works best for the extremely long and thin device [21][22][23][24].…”

“…The concerned performance of the transverse figure of merit (ZT zx ) in ATMTD is defined as ZT zx = σ xx S zx 2 T/κ zz , where the ZT zx , σ xx , S zx , κ zz and T are the transverse figure of merit, transverse electrical conductivity, transverse Seebeck coefficient, transverse thermal conductivity and absolute temperature, respectively [27]. Recently, many efforts have been made to combine different materials to study the ZT zx of ATMTD, such as Al/Si [28], Bi/Cu [29], Pb/Bi 2 Te 3 [30], Ni/Bi 0.5 Sb 1.5 Te 3 [31][32][33], YbAl 3 /Bi 0.5 Sb 1.5 Te 3 [34] and Bi/Bi 0.5 Sb 1.5 Te 3 [24]. However, the geometrical configurations (θ and δ) of the ATMTD also play a very important role in improvement of ZT zx , since it takes advantage of the transverse TE effect in an artificially tilted multilayer structure.…”

Selective Chemical Vapor Deposition Approach for Sb2Te3 Thin Film Micro-thermoelectric Generators

“…Research on micro/nano-TEGs for small scale energy harvesting has developed rapidly within recent years 16,17 20 , electrodeposition 21,22 , zone-melting 23 and pulsed laser deposition 24 were also reported to fabricated tellurium-based micro-TEGs. However, the scarcity (low natural abundance) of tellurium is a serious concern for the mass-production of Bi2Te3 and Sb2Te3 based thermoelectric generators 25 .…”

“…Yuan et al also presented a BiTeSe/BiSbTe-based radial structure micro-TEG through screen-printing, producing an output power of 5.81 μW at a temperature difference of 48.3 K . Other deposition techniques, such as thermal evaporation, electrodeposition, , zone melting, and pulsed laser deposition, were also reported to fabricate tellurium-based micro-TEGs. However, the scarcity (low natural abundance) of tellurium is a serious concern for the mass production of Bi 2 Te 3 - and Sb 2 Te 3 -based thermoelectric generators .…”
