“…In fact, the height, breadth, and length of the Bi2Te2.70Se TEM as well as the thicknesses of the TE material layers (alumina and copper) used in t module are often important variables. We examined every parameter in our earlier repo [26] in relation to a few crucial functions before making a parameter recommendation. addition, the choice of TE materials and the arrangement of the p-and n-type legs a additional characteristics that could be considered when defining a module as standar Every element of the studied TEM's criteria is standard.…”

This research employs the COMSOL Multiphysics software (COMSOL 6.2) to conduct rigorous simulations and assess the performance of a thermoelectric module (TEM) meticulously crafted with alumina (Al2O3), copper (Cu), and Bi2Te2.70Se0.30 thermoelectric (TE) materials. The specific focus is on evaluating diverse aspects of the Bi2Te2.70Se0.30 thermoelectric generator (TEG). The TEM design incorporates Bi2Te2.70Se0.30 for TE legs of the p- and n-type positioned among the Cu layers, Cu as the electrical conductor, and Al2O3 serving as an electrical insulator between the top and bottom layers. A thorough investigation is conducted into critical parameters within the TEM, which include arc length, electric potential, normalized current density, temperature gradient, total heat source, and total net energy rate. The geometric configuration of the square-shaped Bi2Te2.70Se0.30 TEM, measuring 1 mm × 1 mm × 2.5 mm with a 0.25 mm Al2O3 thickness and a 0.125 mm Cu thickness, is scrutinized. This study delves into the transport phenomena of TE devices, exploring the impacts of the Seebeck coefficient (S), thermal conductivity (k), and electrical conductivity (σ) on the temperature differential across the leg geometry. Modeling studies underscore the substantial influence of S = ±2.41 × 10−3 V/K, revealing improved thermal conductivity and decreased electrical conductivity at lower temperatures. The findings highlight the Bi2Te2.70Se0.30 TEM’s high potential for TEG applications, offering valuable insights into design and performance considerations crucial for advancing TE technology.

This study utilized COMSOL Multiphysics to simulate the performance of a thermoelectric module (TEM) made by alumina (Al2O3), copper (Cu), and bismuth telluride (Bi2Te3) materials, specifically exploring different leg geometries. The TEM design had Al2O3 for insulation, Cu for conducting, and Bi2Te3 for TE legs between the Cu layers. Investigated the influence of square and rectangular TE legs with heights of 2.0 mm, 2.75 mm, and 3.5 mm on critical parameters, including temperature gradient, electric potential, normalized current density, and total internal energy within the TEM. Furthermore, the impact of varying thicknesses in the insulator and conductor layers of the TEM was explored. The results consistently demonstrated that the square leg geometry, particularly when configured with a height of 2.75 mm, outperformed other leg geometries. Consequently, it is recommend the adoption of square-shaped Bi2Te3 TEM, measuring 1 mm × 1 mm × 2.75 mm, with a 0.50 mm Al2O3 thickness and 0.125 mm Cu thickness during the manufacturing process. Study how factors like the Seebeck coefficient (S), thermal conductivity (k), and electrical conductivity (σ) affect temperature differences in the leg design of TE devices. At lower temperatures, modeling reveals lower electrical conductivity and enhanced thermal conductivity, highlighting the significance of S = ± 2.37×10⁻⁴ V/K. This illustrates the high potential of TEM for applications in thermoelectric generator (TEG) manufacturing.
