Abstract Bismuth telluride (Bi 2 Te 3 ) has been the only commercialized material in thermoelectric cooling and waste heat recovery. However, inferior performance for n‐type Bi (Te, Se) largely restricts practical applications. In this study, additional Ag atoms are introduced utilizing lattice plainification strategy to enhance electrical performance. Observations indicate that situate van der Waals layers, acting as dopants increase carrier concentration, bonding with adjacent intercalating form electron transport channels, while also suppressing formation of vacancies boost mobility, substantially favoring transport. Consequently, 2.79 Se 0.21 I 0.004 +0.3%Ag achieves an excellent room‐temperature ZT ≈1.1, Te2 .79 + 0.4%Ag demonstrates a higher average ≈1.1 at 300–523 K. Furthermore, full‐scale cooler using optimized combined commercial p‐type 0.5 Sb 1.5 achieved maximum temperature difference (Δ T max ≈68.3 K 300 larger Δ ≈84.8 343 Additionally, 0.4%Ag/Bi ‐based power generator realizes conversion efficiency ≈6.0% under ≈240 These results outperform devices, illustrating effectiveness thermoelectrics.

This study analyzed the significant performance using COMSOL Multiphysics software of thermoelectric modules (TEMs) fabricated from aluminium oxide (Al2O3), copper (Cu), and bismuth telluride (Bi2Te3) materials, with a particular focus on investigating various leg geometries. The TEM design had Al2O3 for insulation, Cu conducting, Bi2Te3 TE legs among Cu. Investigated influence square rectangular heights 2.0, 2.75, 3.5 mm critical parameters such as normalized current density, electric potential, temperature gradient, total internal energy within TEM. Furthermore, impact varying thicknesses in insulator conductor layers was explored. results consistently demonstrated that geometry, particularly when configured height 2.75 mm, outperformed other Consequently, it is suggested to adopt square-shaped measuring 1 × 0.50 thickness 0.125 during manufacturing process. Investigate how differences device are influenced by Seebeck coefficient (S), thermal conductivity (k), electrical (σ). At lower temperatures, modeling reveals enhanced conductivity, highlighting significance S = ± 2.37×10⁻⁴ V/K. illustrates high potential applications generator (TEG) manufacturing.
