Enhancement Performance of Thermoelectric Generators with Superconducting Substrates

Thermoelectric conversion technology is attracting attention due to global warming. In this paper, the experimental measurements and numerical simulations were used to evaluate the impacts of structural parameters, compressive load, and the thermal gradient on the performance of thermoelectric generators (TEG) with different substrates. Compared with our previous studies on the enhancement of TEG performance in terms of material modification, P/N junction structure, thermal field match, and system performance optimization, here the high-performance TEG based on the superconducting substrate were reported, in which the effective thermal resistance, thermal stress, and output power characteristics were measured and discussed.
