| Abstract Scope |
In order to spread thermoelectric (TE) systems widely to solve energy and environmental problems, the long lifetime is one of the indispensable abilities of the TE modules. The mechanical properties at the junctions between the TE materials and the electrodes should be important to not only the power output but also the lifetime of the TE modules. The relationship between mechanical and TE generation properties has been investigated for the high temperature-resistant TE modules. The mechanical properties evaluated by the tensile and the shear strength of the TE material and the electrodes depend on the preparation conditions and the compositions of the Ag-based paste as the bonding material. The degradation of the power output is observed by heat cycling and vibration because of weakening of the joining strength. The accumulated fatigue caused by the dynamic stress should be paid attention to discuss the durability of the thermoelectric modules. |
