| Outline of Final Research Achievements |
Thermoelectric power generation is a technology to obtain electric power from a temperature difference by using thermoelectric materials, and is attracting attention as a new technology to effectively utilize waste heat. For industrial application of the thermoelectric power generation, it is required to manufacture printing-thermoelectric-device with low cost, large area / high density. Thus, many groups in Japan and abroad are developing researches on that printing thermoelectric devices.
In this research project, we developed a Bi-Te thermoelectric ink for the printing, and (1) succeeded in realizing performance equivalent to that of a commercial product by controlling heat treatment conditions and crystal orientation in the nanobulk. Moreover, (2) we succeeded in obtaining a micro-size thermoelectric element pattern by introducing imprinting technology.
This achievement is a key-technology for industrial application of thermoelectric technology and will help solve energy problems.
