One-step post-treatment boosts thermoelectric properties of PEDOT:PSS flexible thin films

Xingyu Liu et al.

Summary: This study develops a one-step post-treatment method using a water-based solution to improve the power factor of PEDOT:PSS films. By using a DMAC solution and LAA reducing agent, the electrical conductivity and Seebeck coefficient of the films are enhanced, resulting in an improved power factor. The research also demonstrates a flexible thermoelectric device assembled with PEDOT:PSS films showing high output power at a temperature difference of 25 K.

High-performance in n-type PbTe-based thermoelectric materials achieved by synergistically dynamic doping and energy filtering

Hang-Tian Liu et al.

Summary: By introducing Ag2Te and dynamically doping silver into n-type Pb0.975Cr0.025Te, a peak figure of merit of 1.5 at 773K was achieved. The high value is attributed to the synergistic optimization of carrier and phonon transports. Ag2Te nanoprecipitates establish coherent interfaces with the matrix to induce energy-dependent carrier scattering and maintain relatively high carrier mobility, leading to optimal electrical-transport properties over a wide temperature range.

Simultaneous enhancement of conductivity and Seebeck coefficient of PEDOT:PSS by triflic acid treatment for flexible thermoelectric generator

Muhammad Zeshan Ali et al.

Summary: Organic thermoelectric materials are of great interest for flexible thermoelectric devices. The trade-off effect between conductivity and Seebeck coefficient is observed in PEDOT:PSS. Triflic acid pre-treatment is used in this work to simultaneously increase conductivity and Seebeck coefficient. The improvement is attributed to the increased order of long-range crystal packing and hopping between newly generated DOS. HRTEM and XRD data confirm the improved crystallinity. Acid treatment induces conformational change in PEDOT:PSS molecules, leading to increased conductivity and Seebeck coefficient.

Achieving high thermoelectric properties in PEDOT:PSS/SWCNTs composite films by a combination of dimethyl sulfoxide doping and NaBH4 dedoping

Li Zhang et al.

Summary: By doping with DMSO and dedoping with NaBH4, the thermoelectric properties of PEDOT:PSS/SWCNTs composite film can be significantly improved, achieving high electrical conductivity and Seebeck coefficient. The high electrical conductivity is achieved by removing insulating PSS, changing the stacking structure of PEDOT chains, and forming a three-dimensional conductive network between PEDOT:PSS and SWCNTs. Dedoping with NaBH4 reduces the oxidation level of PEDOT:PSS, leading to a compromise between electrical conductivity and Seebeck coefficient.

Coherent Sb/CuTe Core/Shell Nanostructure with Large Strain Contrast Boosting the Thermoelectric Performance of n-Type PbTe

Shixuan Liu et al.

Summary: The introduction of Sb and Cu2Te into an n-type base material (PbTe)(81)-Sb2Te3 effectively tunes the electron concentration and enhances the overall Seebeck coefficient. The co-precipitation of Sb and Cu2Te forms an interesting Sb/CuTe core/shell structure, showing interface characteristics beneficial for electron transport but adverse to phonon transport. The peak ZT(max) of approximately 1.6 @ 823K and averageZT of approximately 1.0 (323-823 K) are achieved in the (PbTe)(81)Sb2Te3-0.6Sb-2Cu(2)Te sample, representing the current state of the art for n-type PbTe-based thermoelectric materials.
