| Abstract |
| The increasing global demand for alternative energy sources and the environmental
consequences of climate change necessitate research into renewable energy sources
and energy conversion processes. Thermoelectric technology, which converts heat
directly to electricity, can solve the energy issue and provide greener energy sources.
The effects of yttria-stabilized zirconia (YSZ) on thermoelectric properties, such as
electrical resistivity and Seebeck coefficients, of YSZ/ZnO composite have been
investigated in this research. The study investigates the influence of sintering ZnO
ceramics in an argon atmosphere at 1450oC with various quantities of YSZ addition
to the microstructure and thermoelectric properties. The solid-state reaction method
was used to synthesize all ZnO ceramic samples without YSZ and with YSZ of 0.5, 2
and 3 wt%. The Seebeck coefficient of the sintered samples increased 44-92% with
YSZ additions at 800oC. At 800oC, the nominal composition of 0.5 wt% YSZ had power
factor 1505 W.m–1.K–2
