The Thermoelectric Cooler Performance Coefficient Based on Configuration of p-type and n-type Semiconductors of Bi ₂ Te ₃ Materials

This research aims to perform fabrication and simulation of thermoelectric cooler module with Bismuth Telluride (Bi2Te3) semiconductor material. The results obtained from this research is the higher the value of the given current, then the temperature difference generated by the module will be higher and the preparation of semiconductors in series can produce the highest temperature difference. The coefficient of performance (COP) of the cooler thermoelectric module is influenced by several factors, among others, given current, electrical resistance, seebeck coefficient, and thermal conductance of the module The lowest consecutive temperature values are generated by module three on the Ampere current five, the module of the two Ampere current pads, and the module one on the four Ampere current. The coefficients of the performance of module one on the four Ampere currents are 0.12881 ± 0.000005; in the second module when the current flow of 4.5 amperes is 0.63361 ± 0.000005; and in the three modules when the current flow of five amperes is 0.92906 ± 0.000005. The error values of the measurement and simulation results respectively in module one, module two, and module three are 7.041%; 5.577%; and 10.387%.
