A Research for the Thermoelectric Energy Harvester to Improve the Power Generation Efficiency

This study suggests using thermoelectric element to generate electric energy from the heat source efficiently. This generator system consists of a Heater, the Lower Heat Transfer Plate to absorb heat from the Heater, Two-Stage Thermoelectric Device module to generate the electric power with the heat transferred from the Lower Heat Transfer Plate, the Upper Heat Transfer Plate to convey the heat from the Two-Stage Thermoelectric Device module to Hat Sink, and the Heat Sink to release the heat from the Upper Heat Transfer Plate. By comparing the Two-Stage Thermoelectric Device module system with using one thermoelectric element, we have found that the Two-Stage method is more efficient to generate electric energy from the same heat source.
