Boosting the performance of printed thermoelectric materials by inducing morphological anisotropy

Abstract

Thermoelectrics can generate electrical energy from waste heat and work also as active coolers. However, their widespread use is hindered by their poor efficiency, which is aggravated by their costly...

ThermoelectricMgAgSballoys for sustainable energy application

“…Many TE materials and TE systems are widely utilized in energy generation applications. 8 Bi 2 Te 3 -based TE materials have been used commercially in solid-state refrigeration due to their higher ZT (ZT > 1) at room temperature. However, the scarcity of the Te element essentially limits the commercial uses of Bi 2 Te 3 -based materials.…”

Effects of cation size on thermoelectricity of PEDOT:PSS/ionic liquid hybrid films for wearable thermoelectric generator application

“…Moreover, the diverse morphologies and structures of the conducting polymers can be easily tuned through many approaches, such as chain alignment, nanostructuring, and doping, to manipulate their charge transport as well as thermoelectric characteristics. 17–24…”

“…Moreover, the diverse morphologies and structures of the conducting polymers can be easily tuned through many approaches, such as chain alignment, nanostructuring, and doping, to manipulate their charge transport as well as thermoelectric characteristics. [17][18][19][20][21][22][23][24] Within these conjugated polymer systems, poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS), with its enhanced solubility from the aqueous dispersion of soluble polymeric counterions, has gained attention as a state-of-the-art thermoelectric polymer and is currently the best-performing conjugated polymer. [25][26][27][28][29][30][31] To date, strategies that can improve the overall thermoelectric properties of a PEDOT:PSS lm determined by using the power factor have been studied.…”

Interfacial‐Modulated Growth of Nanostructured Bi2Te3 Films for Enhancing Thermoelectric Performance

“…Bi 2 Te 3 -based nanoplates with high boundary density can be solution synthesized to enhance the scattering of phonons and thus reduce κ. [17,18] Further adjustments to the arrangement, [19,20] heterostructures, [21,22] and pores [23,24] of the nanoplates can optimize their TE performance. However, transforming colloidal nanoplates into high-performance devices remains a challenge because films prepared by DOI: 10.1002/pssa.202200108 Little room remains for further reducing lattice thermal conductivity (κ L ) which cannot be reduced below the amorphous limit.…”
