Abstract—The processing of waste heat harvested from industrial or domestic installations directly converted into electrical energy using thermoelectric generators (TEG) is an interesting and future-proof solution. The main advantages of these types of generators are the absence of moving, defective parts and very long durability, their main disadvantage - the low efficiency. The generator is a serial connection of up to tens of p-n thermocouples, through which the current of as many as dozen amps can flow. Its quality and reliability depends not only on semiconductor parameters, but also on other structural materials such as ceramics, metals or solder alloys. This paper presents technical findings of research into a semiconductor PbTe thermogenerator(TEG) model. It involves an analysis of possible defects in assembly and their influence on thermogenerator. Ways of mitigating such defects are also discussed.
