Modelling and simulation of a thermoelectric structure with pellets of non-standard geometry and materials

•Characterization of a non-standard thermoelectric structure.•Direct relation between thermoelectric properties and pellet material.•Good correlation between simulation, experimental and computational results.•Verification of good performance of the Finite Element Model used.

The aim of this paper is to develop and manufacture a thermoelectric structure operating in Peltier mode with non-standard materials, using a Finite Element Model. Thus, both the reliability of the Finite Element Model and the correct development and design of the new thermoelectric structure are ascertained, achieving a dual goal of our research group. This work provides a very good correlation between simulated and experimental results, and corroborates that the material's performance has a decisive influence on the thermoelectric properties of the structure in the temperature range of study considered.
