THERMOELECTRIC GENERATORS MADE OF FESI2 AND HMS - FABRICATION AND MEASUREMENT

Single couple thermoelectric generators consisting of n-type FeSi2 and p-type higher manganese silicide were developed and characterized. Th e leg and the bridge materials were prepared by a powder metallurgical method. Using the Peltier effect the transport properties were measur ed over the whole working temperature range. Electrical contacts suita ble for the hot side could be obtained by conventional vacuum solderin g and those for the cold side by ultrasonic soldering. The measured ef ficiency was in excellent agreement with the calculated values derived from the leg and contact properties.
