Resumo
The possibility of increasing the efficiency of a thermocouple in the temperature range of 30–320°C is studied using an approach associated with the development of segmented thermoelectric unicouples. n- and p-type thermoelectric unicouples are constructed from low-temperature thermoelectric materials based on bismuth telluride and the addition of an intermediate-temperature material based on PbTe and GeTe, respectively. The thermoelectric unicouples are fabricated by spark plasma sintering (SPS). This method provides a contact resistance of ≤10 μΩ cm. The properties of segmented and conventional unicouples are compared. The efficiency of segmented unicouples in comparison with conventional ones increases by almost 70% and attains 5.3% in the operating range of 30–320°C.
