This work focuses on performance investigation of a low cost thermoelectric module fabricated from p-type sodium cobalt oxide and n-type Cu-Zn alloy. The waste heat conversion measurements indicated that the developed module generated output voltages of 0.35 mV/K and 0.85 mV/K at temperature differences of 1-6 K and 8-14 K, respectively. As the result, this thermoelectric module may be suitable candidate as an electrical generator in moderate voltage applications.Mahidol UniversityAgricultural and Biological SciencesEnvironmental ScienceArticleSCOPUS
