Comprehensive Matlab code for determination of properties and internal thermal contact resistances of suspended thermoelectric modules by impedance spectroscopy

This code allows performing fittings and simulations to suspended modules in vacuum. It can identify the material’s properties, module ZT, and the internal thermal contact resistances. The code is the same published in the Supplementary Material of the open-access article Comprehensive impedance spectroscopy equivalent circuit of a thermoelectric device which includes the internal thermal contact resistances from Applied Energy 299 (2021) 117287. The code uses the equivalent circuit of Fig. 2b of this article.

Matlab code for the detailed assessment of thermoelectric modules by impedance spectroscopy

This code allows performing a qualitative analysis via simulations of a thermoelectric module with standard architecture in order to identify the internal thermal contact resistances. Further information about this code can be found in Chapter 7 of the PhD Thesis of Braulio Beltrán-Pitarch. It should be noted that the code does not include the effect of the inductance of the system, for this reason it is recommended to use the code above from the Applied Energy 299 (2021) 117287 open-access article.

Matlab code for the determination of the thermal contact resistance between a thermoelectric module and heat sinks by impedance spectroscopy

This code allows determining the thermal contact resistance of a thermoelectric module which is sandwiched between heat sinks. The thermal contact is between the outer ceramic layers and the heat sinks. More information can be found here.
