Variable temperature effects on TEG performance

Abstract

The present paper presents an experimental investigation of the variable temperature effects on the performance of a Thermoelectric Generator (TEG). In the conducted experiments, a sample TEG is analyzed by imposing variable temperature patterns on the cold side, while keeping the temperature uniformon the hot side. The achieved local temperature variations on the cold side has approximately been about 8% of the temperature difference between the hot and cold sides. The results reveal that the TEG performance shows some variation with the applied variable temperature patterns, which remains, however,rather small for the applied temperature variations. For achieving a more clear answer to the present question, further experiments need to be designed where more substantial temperature variations canbeobtained.
