Abstract: 
Within thermoelectric generators, the chemical diffusion of a contact
material into the active thermoelectric material is a potential cause
for degradation, which has rarely been discussed in literature.
Frequently, this degradation phenomenon leads to major problems in
developing new modules and achieving long-term stability. In this study,
copper as one of the standard contact materials and lead telluride as
the state-of-the-art active material in the mid-temperature range are
investigated. Chemical diffusion experiments of copper in lead telluride
were carried out between 375 K and 795 K and the copper diffusion
profiles were obtained by Secondary Ion Mass Spectrometry (SIMS). The
evaluated chemical diffusion coefficient is lower than 10⁻¹³ cm²/s in the respective temperature range.
