dc.description.abstract | The issue of global warming has garnered worldwide attention, highlighting the importance of seeking environmentally friendly and sustainable energy sources. With advancements in nanotechnology, thermoelectric materials have emerged as an excellent option for converting heat into electricity. By harnessing temperature differentials, these materials can generate electrical power, thereby enhancing energy efficiency. Consequently, they find practical applications in settings such as factories or vehicles that generate substantial amounts of waste heat.
The characteristics of thermoelectric materials vary based on the specific materials employed. Among them, oxide semiconductors possess desirable attributes such as thermal stability, chemical stability, non-toxicity, and environmental friendliness, making them an ideal choice for thermoelectric applications.
This study focuses on zinc oxide (ZnO) materials. N-type and P-type samples were prepared by doping ZnO with different elements. The N-type material was doped with 2 at% Al2O3 and CeO2, while the P-type material was doped with 0.192 at% of ZnP. To construct thermoelectric modules, contact metals such as silver paste, nickel paste, copper foil, nickel foil, and tantalum foil were employed. The output power of these modules was measured at various temperatures. | en_US |
