Thermoelectric Energy Conversion

This article is focused on thermoelectric cooling (TEC) and thermoelectric power generation (TEG). Detailed theoretical modeling and characterization were presented with the key performance highlighted. Heat transfers from heat sinks on both hot and cold surfaces of the thermoelectric models were discussed and measures to enhance and increase heat transfer rates were proposed. Waste heat from the steel industry, vehicle exhaust gas and solar energy for TEG power generation were discussed. Two advanced technologies, i.e., two-stage TEG and heat pipe assisted TEG, were listed to increase the overall efficiencies of power generation.
