| dc.description.abstract | As technology advances, AI and electric vehicles are rapidly developing. The increasing energy consumption and depletion of fossil fuels, coupled with rising environmental awareness, have spurred interest in alternative energy sources, particularly renewable energy. Thermoelectric materials, which can convert heat into electricity and vice versa, play a critical role in this field, offering potential in energy recovery, cooling systems, and renewable energy applications.
This experiment builds on previous research with N-type Mg2(SiSn) thermoelectric materials. We prepared N-type thermoelectric components by mixing a fixed proportion of Mg2Si with Mg2(SiSn), followed by powder doping, mixing, placing contact metals, cold pressing, and high-temperature sintering. Electrical measurements and analyses were conducted to determine the optimal doping ratios and contact metals. These N-type components were then paired with P-type Mg2(SiSn) materials to form single PN-type thermoelectric devices. Finally, we selected the best-performing PN devices and produced them in large quantities. These devices were welded into a large-scale module, achieving an output voltage of 1V. | en_US |
