This simulation tool is an upgraded version of our THERMO tool (see tool #2 below) developed for thermoelectric module power generation simulations. Unlike THERMO tool, ADVTE tool allows user to upload their own temperature-dependent material properties, i.e. Seebeck coefficient, electrical conductivity, and thermal conductivity as functions of temperature for the thermoelectric materials used in the module, and perform realistic module simulations for waste heat recovery and energy harvesting applications. Use of temperature-dependent material properties is particularly important for accurate module simulation when the temperature difference applied across the module is so large that the material properties are no longer constant over the temperature range.
This online simulator is intended to simulate operations of TE devices under various circumstances and boundary conditions. Both micro-scale thin-film TE devices and large-scale multi-element TE modules can be simulated. Users can choose an independent variable such as design parameters of the TE device, and simulation conditions, and simulate the device performances as a function of the independent variable.

This simulator allows users to calculate various thermoelectric properties such as Seebeck coefficient, electrical conductivity, and electronic thermal conductivity for any semiconductor materials with band structures modeled using the nonparabolic dispersion relation. The linearized Boltzmann transport equation under the relaxation time approximation is employed for the calculations. Please click the link below to run the simulator:
In this simulation tool, a thermoelectric power generator is optimized together with the heat source and heat sinks for maximum power output and system cost. Full electrical and thermal co-optimization is performed with given material properties, and dimensions to find the optimal thickness of the thermoelectric elements. One can choose a material property such as Seebeck coefficient and thermal conductivity as an independent variable to optimize the performance of the power generator as a function of the chosen material property. Heat transfer coefficients of the heat sinks at the hot and cold sides can also be varied as an independent variable. Please click the link below to run the simulator:
