ABSTRACTThermoelectric power generation has been attracting attention as a technology for waste heat utilization in which thermal energy is directly converted into electric energy. It is well known that layered cobalt oxide compounds such as NaCo2O4 and Ca3Co4O9 have high thermoelectric properties in p-type oxide semiconductors. However, in most cases, the thermoelectric properties in n-type oxide materials are not as high. Therefore, n-type magnesium silicide (Mg2Si) has been studied as an alternative due to its non-toxicity, environmental friendliness, lightweight property, and comparative abundance compared with other TE systems. In this study, we fabricated π-structure thermoelectric power generation devices using p-type NaCo2O4 elements and n-type Mg2Si elements. The p- and n-type sintering bodies were fabricated by spark plasma sintering (SPS). To reduce the resistance at the interface between elements and electrodes, we processed the surface of the elements before fabricating the devices. The end face of a Mg2Si element was covered with Ni by SPS and that of a NaCo2O4 element was coated with Ag by silver paste and soldering.The thermoelectric device consisted of 18 pairs of p-type and n-type legs connected with Ag electrodes. The cross-sectional and thickness dimensions of the p-type elements were 3.0 mm × 5.0 mm × 7.6 mm (t) and those of the n-type elements were 3.0 mm × 3.0 mm × 7.6 mm (t). The open circuit voltage was 1.9 V and the maximum output power was 1.4 W at a heat source temperature of 873 K and a cooling water temperature of 283 K in air.

New Findings

Authors report methodical studies on some novel, alternative energy technologies, and produced results of a thermoelectric power generation (TEPG) system. For the sake of evaluating critical thermoelectric (TE) features, they have invented the state-of-the-art equipment that has important specification capability. The studies cover the efficiency and many aspects of TEPG features as follows. A thermoelectric module is measured in situ that includes TE efficiency, force response curve, current-voltage (I-V) and power-voltage (P-V) characterization, and power temperature (P-T) response curve. They have improved both the higher total output power and the more efficient TEPG efficiency than their comparison TE devices and systems in their studies. In addition, authors will present a series of design, construction, and characterization of a thermal electric generation system which aims to achieve a large power output and high efficiency for the energy harvesting application. Furthermore, their studies lead to important knowledge of TEPG systems in terms of multi-stack modules and of the optimization in TEPG applications. Finally, the prototypes are built for both the tabletop and other applications with new findings. Several sets of prototype TEPG are developed for experimental investigation and data analysis, followed by the summary and conclusions based on the data.
