Brief Description
The aim of the joint project "TE-K-System" is the development of ceramic based, robust and cost-efficient thermoelectric generators (TEG). A TEG can convert thermal energy directly into electrical energy.
The aim of the subproject relates to the development of a laser joining technology for the different components of the ceramic TEG system. For this reason, it is necessary to develop special high temperature resistant solders compatible with the electrically isolating ceramics, the thermoelectric ceramics and the metallic conductors. Previously used solders are basically unsuitable for the joining of these new ceramic TEGs because of the difference of materials, lower soldering temperatures and longer process times.
An adaptation of the method for laser beam joining of ceramic materials developed at TU Dresden opens up an efficient and reliable way of producing ceramic TEG modules for higher temperature application.
In addition, the laser beam technology is well suited for integration into automated production lines and promises very short production times. In particular, these short production times and the high degree of laser automation make it possible to strive for a cost-effective mass production, which is a precondition for broad application fields.
