“…Recently, thermoelectric generators spanned their diligence to solar thermal and photovoltaic schemes, where the cost of the thermal energy input is not an issue [5,6]. The idea of thermoelectrics was discovered by Thomas Johann Seebeck in 1821 [7], in which a compass needle was deflected if it was brought near to a closed loop, made up of two different electrical conductors when any one of the junctions was heated [8]. Thirteen years after the Seebeck's experiment, J.C.A.…”

“…It was unknown that the Seebeck and the Peltier phenomena are dependent on each other until W. Thomson related the Seebeck and Peltier effects coefficients through thermodynamics. In 1949, Abram Fedorovich introduced the thermoelectric figure of merit ZT, which linked the performance of the thermoelectric with the physics of semiconductors; this parameter measured the thermoelectric efficiency and performance by revealing the balance between the materials electrical and thermal properties [7][8][9]. Altenkirch demonstrated that a good thermoelectric material ought to have a large Seebeck coefficient, and it should possess low thermal conductivity, and these appropriate properties were represented in the commonly named figure of merit (ZT) [8].…”

The scope of thermoelectric generators (TEGs), in improving the electric vehicle battery performance and glass/steel manufacturing industries, could achieve wider significance by harnessing the unused radiative heat and light conversion to electrical power. This paper experimentally investigates the electrical performance correlated to concentrated quartz-halogen, with acrylic Fresnel lens and heat-light harvesting, coupled with heat sink. This study also experimentally examined the influence of extreme temperature variance on the open circuit generated voltage of the Peltier electrical failure mode, compared to the standard performance parameters of the commercial TEG module. The research results presented provide expedient perception into the testing (open circuit voltage, short circuit current, and full load power) of a commercial heat-stove TEG to understand its performance limitations. The analytical simulation and mathematical model developed in MATLAB compared the electrical performance parameters and its dependencies. The analytical simulation shows that increasing the heat-sink temperature increases the efficiency of not more than 2% at the Δ T of 360 K, due to the limitation of the Z T ¯ of 0.43 at Δ T of 390 K. The maximum Z T ¯ of 0.7 for Bi2Te3, with an achievable efficiency of 4.5% at the Seebeck coefficient of 250 µV/K, was predicted. The design of three experimental setups and results presented demonstrate the functioning of TEG in stable and unstable temperature conditions, confirming the theoretical study and stipulating a quantity of the electrical output power in relation to extreme temperature conditions.

“…Also, the temperature dependence of the materials electrical resistivity (ρ) was neglected in the analytical model. The Although the Seebeck coefficient varies with temperature, it was considered constant and equal to 200 µV/K [23] for type p, and of opposite value for type n. The contribution of the copper (Cu) to the thermoelectric effect was neglected because the intermediate conductors law says that the contribution of a homogeneous conductor to the voltage is zero when its extremes are at the same temperature (5). The same is true for ceramics and the graphite film.…”

“…The output power produced by the generator can be calculated using the values of resistance and voltage, considering that a constant temperature is maintained between the junctions, according to Equation (5). Likewise, the maximum output power occurs when the load resistance has the same value of the internal resistance (Equation (6)).…”

Analytical and Numerical Study for the Determination of a Thermoelectric Generator’s Internal Resistance

The conversion of residual thermal energy into electricity using TEGs (Thermoelectric Generators) arises as a promising technological alternative for increasing energy efficiency and power generation. In order to optimize the performance of TEGs, it is known that the maximum output power is obtained by matching the impedances between the TEG and the connected load. Therefore, the objective of this work is to present the development of a numerical and a simplified analytical model to determine the internal resistance (R int ) and predict the open circuit voltage, charge voltage, current and power values of TEGs. The models have used as reference the thermoelectric module TEHP 1263-1.5 (Thermonamic), with the analytical one being based on the classical theory of electrical circuit analysis and, for the numerical one, a three-dimensional geometric model was developed and the set of equations were solved in the COMSOL Multiphysics ® tool by the finite element method. The R int obtained by the analytical and numerical models were, respectively, 3.157 Ω and 6.027 Ω, and the value supplied by the supplier is 3.154 Ω. Therefore, the analytical model is indicated as a reference to estimate R int of the TEG, allowing optimizing its use by choosing the load resistance that will result in the maximum power.
