A novel 3D TCAD simulation of a thermoelectric couple configured for thermoelectric power generation

Abstract

This paper documents the novel design, modelling and 3D simulation of a single thermoelectric couple using the Technology Computer Aided Design (TCAD) semiconductor simulation software package by Synopsys. Preliminary simulation results are presented for thermoelectric power generation, and successfully demonstrate the basic thermoelectric effects, and how the application of a temperature gradient to a thermoelectric couple results in a small amount of electrical power being generated at a load resistor. The TCAD simulation model will enable further investigation in the future into different material structures, thermoelectric couple and module design, and the improvement in efficiency and thermoelectric module performance.
