Synthesis of Zn0.96Al0.04O thermoelectric material for fabrication of thermoelectric module and thermoelectric generator

Abstract

The main objective of this work is aim to synthesize Zn0.96Al0.04O thermoelectric materials for fabricating thermoelectric modules and inventing thermoelectric generator. The Zn0.96Al0.04O sample was prepared by a conventional solid state reaction method. The formation of structure was proved by X-ray diffraction and the thermoelectric properties were measured. The results presented that the Zn0.96Al0.04O displayed thermoelectric materials and showed the thermoelectric properties as higher than that of ZnO based. The Zn0.96Al0.04O thermoelectric modules displayed the electric power was increased with number of module, large temperature difference and operation at high temperature. The Zn0.96Al0.04O thermoelectric generator showed high performance for electric generator at high temperature. The sixteen Zn0.96Al0.04O legs thermoelectric generator can generate electric power 1.4 mW at 800 in ΔT = 600 C. Thus, the Zn0.96Al0.04O thermoelectric material can be used for application of thermoelectric generator at high temperature.
