Abstract
As the energy demand grows, people are devising new ways to generate energy. New energy sources will be required to close the energy gap. Distributed energy generation is gaining popularity because of its several benefits, including adaptability, reliability, and adaptability, as well as the fact that it has low transmission losses. The thermoelectric generator is a distributed power source that produces electricity using thermal energy (TEG). The conversion efficiency is measured in terms that are unaffected by module geometry. This means that the thermoelectric generator design is only governed by matching the load resistance to maximise efficiency or power production.
On the other hand, the thermoelectric module's power output and conversion efficiency are determined by the thermoelement length, contact properties, and operational temperature difference. The optimal length for maximum power production differs from that for maximum conversion efficiency. The ideal length of a thermoelement for power generation appears to be a compromise between the need for maximal power output and conversion efficiency. This paper aims to give the calculations and graphs required to determine the best module configuration.
