Theoretical analysis of thermoelectric module

A thermoelectric generator was used to recover waste heat from a source, such as engine exhaust. The key elements of the are exchanger and module. Thermoelectric modules convert energy electrical using Seebeck effect. temperature difference between hot cold sides module is required generate electric power. theoretical model developed predict current, voltage, power output. bismuth Telluride for analysis. It observed that voltage increased with external load resistance, output at certain resistance then decreased. Under match condition, maximum obtained.
