Applications of impedance spectroscopy in thermoelectricity
The Abdus Salam International Centre for Theoretical Physics (ICTP) (2019-03-12)t is widely used in a lot of different fields (solar cells, fuel cells, corrosion, supercapacitors, batteries, etc.). • Powerful and very reliable equipment are available in the market. • It allows the separation of the ... -
Characterization of thermal contacts between heat exchangers and a thermoelectric module by impedance spectroscopy
Elsevier (2019)Heat to electricity energy conversion efficiency of a thermoelectric (TE) device is not only influenced by the TE materials properties, but it also depends on the temperature difference between both sides of the TE legs. ... -
Determination of the thermoelectric properties of a skutterudite-based device at practical operating temperatures by impedance spectroscopy
Elsevier (2019-10-01)Skutterudite-based thermoelectric materials are promising candidates for waste heat recovery applications at intermediate temperatures (300–500 °C) owing to their high dimensionless figure of merit and power factor. Recently, ... -
Determination of thermal conductivity, thermal diffusivity, and specific heat of liquids using a thermoelectric module
IOP Publishing (2024)Managing heat through working fluids is essential in many applications, as well as the development of new fluids with improved properties. Therefore, the characterization of their thermal properties, which is usually a ... -
Evaluation of in-plane architecture in a thermo-electrochemical cell with nanostructured and porous Sb:SnO2 electrodes
Elsevier (2024-05-11)Thermo-electrochemical cells (TECs) are able to convert heat into electricity. They are formed by two electrodes (typically Pt) separated by a redox electrolyte (usually 0.4 M aqueous ferro/ferricyanide). The widely adopted ... -
Experimental conditions required for accurate measurements of electrical resistivity, thermal conductivity, and dimensionless figure of merit (ZT) using Harman and impedance spectroscopy methods
AIP Publishing (2019-01-11)The Harman method is used extensively for the characterization of the dimensionless figure of merit ZT of thermoelectric (TE) materials and devices. However, its accuracy has often been questioned, since in many cases there ... -
Towards a comprehensive model for characterising and assessing thermoelectric modules by impedance spectroscopy
Elsevier (2018-09-15)Thermoelectric devices have potential energy conversion applications ranging from space exploration through to mass-market products. Standardised, accurate and repeatable high-throughput measurement of their properties is ...
