| dc.description.abstract | In recent years, heat recovery technology has become more mature, and the potential applications of thermoelectric modules are considerable, such as manufacturing industries, or household electricity, automobile waste heat, solar power and other domestic electricity, thermoelectric materials rely on temperature difference power generation, but due to the low conversion efficiency of the thermoelectric materials in the past, the development is relatively slow. With the maturity of the micro-nano structure technology, more thermoelectric materials with better characteristics have been studied and discussed, and more creative technologies have been developed. It is a green energy technology worth looking forward to.
This paper will use aluminum-doped zinc oxide material (AZO), and then try to compound 2.5at%~20at% zinc selenide or zinc sulfide, and analyze the thermoelectric characteristics of various proportions for comparison. We found that when compounding zinc selenide at 4.5at%, the thermoelectric characteristics are excellent. Therefore, we combine this thermoelectric material with P-type thermoelectric material to produce a thermoelectric module and measure its power generation. Although this experiment succeeded in improving the thermoelectric characteristics of AZO and reducing the thermal conductivity through the composite zinc selenide, it did not significantly improve the Seebeck coefficient. It is hoped that this experiment can be used for the future work, and try to find more suitable composite material in the future to develop better thermoelectric properties. | en_US |
