Flexible Thermoelectric Materials and Generators: Challenges and Innovations

“…Current studies on FTEs mainly focus on two aspects of these materials: 1) the development of high‐performance FTE materials, and 2) the fabrication of high‐output FTE devices through rational design . In terms of material development, one strategy is to utilize conductive polymers, including poly(3,4‐ethylenedioxythiophene) (PEDOT), poly(3‐hexylthiophene‐2,5‐diyl) (P3HT), poly(3‐butylthiophene) (P3BT), polyaniline (PANI), polyacetylene (PA), polypyrrole (PPy), and polythiophenes (PTs), due to their intrinsic flexibility and conductivity . Additionally, conductive polymers are abundant, nontoxic or low‐toxicity, and generally easy to shape and process for industrial applications .…”

“…[53,54] Additionally, conductive polymers are abundant, nontoxic or low-toxicity, and generally easy to shape and process for industrial applications. [53,55] The major drawback of conductive polymers is their poor electrical transport properties, [56][57][58][59] which can be improved by doping [34,35,60] and secondary doping engineering. [29,61,62] Another potential method is to develop organic/inorganic hybrids, including incorporating TE fillers into conductive polymers via ex situ [63][64][65] and in situ synthesis, [66][67][68] or by intercalating organic molecules into inorganic layered structures.…”

Controlled formation of Schottky diodes on n-doped ZnO layers by deposition of p-conductive polymer layers with oxidative chemical vapor deposition

“…One very promising polymer is poly(3,4-ethylenedioxythiophene) (PEDOT), which is holeconductive, has reported conductivities>6000 S cm −1 [4], is largely transparent in the visible spectral range and highly flexible [5]. Among many other applications, PEDOT is already used in transparent electrodes [3], in energy conversion and storage devices [6] or for thermoelectrics [7].…”

Key parameters for enhancing the thermoelectric power factor of PEDOT:PSS/PANI-CSA multilayer thin films

“…Moreover, the thermal conductivity of polymers is intrinsically low and the thermal conductivity of such ML thin lms will be even lower because of the phonon scattering at the chain/grain boundaries. 12 PEDOT:PSS and PANI-CSA are the two major polymers that have been used for various applications such as TE thin lms, solar cells, and energy devices. [13][14][15][16][17] PEDOT:PSS has been widely used polymer to fabricate organic TE thin lms so that various strategies have been developed to improve the TE parameterselectrical conductivity (s) and Seebeck coefficient (S).…”
