Abstract

In the current work p-Pb0.94Yb0.06Se:Se and n-Pb0.94Yb0.06Se thin films were fabricated in a thermoelectric devices are composed of 20-pair and 10-pair deposited on a glass substrate using simple thermal evaporation method. The dimension of thin films thermoelectric micro-devices which consist of 20-pairs and 10-pair of legs connected by aluminum electrodes (Al-electrode) was 23 mm ×20 mm and 12 mm ×10 mm, respectively. The 20-pair p–n thermocouples in series device generated output maximum open-circuit voltage of 137.84 mV and a maximum output power up to 25.85 nW at temperature difference ΔT = 115 K, and 84.18 mV and 12.21 nW at ΔT = 162 K, for 10-pair, respectively at ΔT=128 K..
