Enhancement of the thermoelectric properties in β-Cu2+xSe/a-C nano-multilayer films by heterogeneous interfaces

Guipeng Li et al.

Summary: The β-Cu2+xSe/a-C nano-multilayer films were prepared, and their thermoelectric properties were investigated. The modulation periods were found to affect the carrier concentration, mobility, thermal conductivity, resistivity, and Seebeck coefficient. The nano-multilayer films exhibited enhanced power factor and ZT values, which were attributed to the scattering effect of the depletion layer at the β-Cu2+xSe/a-C interface and the presence of the heterogeneous interface.

Thermoelectric transportation in Cu-added Ca3Co4O9 ceramics consolidated by spark plasma sintering

Muhammad Umer Iqbal et al.

Summary: During the last decade, misfit layered calcium cobaltite (Ca3Co4O9) has been explored as a potential thermoelectric material. In this study, the thermoelectric properties of Ca3Co4O9 were improved by synthesizing composites with different wt.% of Cu. The composites were consolidated into bulk ceramics and their structure was analyzed, revealing a multiphase system. The sample containing 5% Cu demonstrated the highest power factor at 973K, which resulted from the simultaneous improvement in electrical conductivity and Seebeck coefficient. The conduction mechanisms were further discussed.

Review on recent development on thermoelectric functions of PEDOT:PSS based systems

Abdullah F. Al Naim et al.

Summary: Organic thermoelectric (TE) materials, especially PEDOT:PSS, have shown great potential in converting heat energy into electrical energy. The TE performance of PEDOT:PSS can be further improved by combining it with various composites, such as alloys, tellurium, nanocarbon structures, and ternary systems. In addition, inorganic fillers, including tellurium and other materials, have also been found to enhance the TE functions of PEDOT:PSS composites. This summary provides an overview of the recent advances in TE improvement and suggests future strategies for developing more effective organic thermoelectric materials.

Thermoelectric Properties of PEDOT:PSS Containing Connected Copper Selenide Nanowires Synthesized by the Photoreduction Method

Shunya Sakane et al.

Summary: This study successfully improved the thermoelectric performance of organic materials by introducing Cu2Se nanowires. The composite films showed a significant increase in electrical conductivity when they contained an appropriate amount of Cu2Se nanowires. This increase was attributed to the percolation effect formed by the Cu2Se nanowires, which brought about high electrical conductivity. The enhancement of the power factor through the percolation effect is expected to contribute to the development of thermoelectric performance for organic materials.

Enhanced-Performance PEDOT:PSS/Cu2Se-Based Composite Films for Wearable Thermoelectric Power Generators

Yao Lu et al.

Summary: In this study, a flexible PEDOT:PSS/Cu2Se-based nanocomposite film was prepared on a nylon membrane using vacuum filtration and hot pressing, demonstrating significantly improved thermoelectric properties. The optimized film showed a high power factor at 400K and excellent flexibility, retaining 85% of the power factor after 1000 bending cycles. Additionally, when paired with n-type PEDOT/Ag2Se/CuAgSe films, a flexible TE generator produced a maximum voltage and power output at a temperature difference of 44K.

Summary: By using carbon nanotubes-tellurium-PEDOT:PSS nanocomposites, it is possible to achieve ultra-low thermal conductivity at high CNT content, which is understood through quantitative mappings of thermal conductivity in micro-scale interface regions. Moreover, the formation of highly conductive layers at the interfaces of Te PEDOT:PSS and CNTs PEDOT:PSS can enhance electrical conductivity and Seebeck coefficient simultaneously.
