“…They showed that the conversion efficiency and working temperature range could be greatly improved by segmenting multiple materials, which in turn increased the device efficiency. Generator modules of segmented thermoelements were studied by Vikhor and Anatychuk [15]. They demonstrated that the efficiency of modules of double-segmented legs was approximately 7.5% and exceeded the power efficiency of homogeneous material generators.…”

Previously, the Institute of Thermoelectricity has created Bi 2 Te 3 -based modules with an efficiency of $7% in the temperature range of 30°C to 300°C, with legs that employed homogeneous thermoelectric materials. Herein, we present the results of development of such modules with legs made of inhomogeneous materials. Based on the theory of optimal control and object-oriented computer technology, programs to determine the requirements for material properties in the inhomogeneous legs were created. It was established that introduction of inhomogeneity in the form of continuous and step changes in three-segment n-and p-type legs yields almost identical efficiency increases of about 15%. Use of two segments reduces this value of 10% to 12%. Modules with twosegment legs encapsulated in thin-walled metal cases filled with inert gas have been built, yielding improved efficiency of 7.8% to 8%.

“…Integrating (13) and taking into account the boundary conditions (12) (17) Thus, the efficiency of TEG model with distributed parameters D TEG can be factor of 1.5 greater than the efficiency of TEG with lumped parameters max TEG other things being equal, which makes it reasonable to use segments in TEG for vehicles.…”
