The hopping charge transfer in the ionconductive material is analyzed and experimentally investigated as the thermoelectric power generation. The physical model for the phenomenon as well as experimental results are analyzed in means of practical implementation with power conversion for energy harvesting from heat wastes or wide-spectrum solar radiation. Provided analysis addresses the thermoel...

Dynamical nonlinear systems provide a new approach to the old problem of increasing the efficiency of thermoelectric machines. In this review, we discuss stylized models of classical dynamics, including non-interacting complex molecules in an ergodic billiard, a disordered hard-point gas and an abstract thermoelectric machine. The main focus will be on the physical mechanisms, unveiled by these...

We revisit the classical problem of the efficiency of inhomogeneous thermoelectric generators. The effects of different physical parameters on the efficiency of a generator are studied by solving the Domenicali’s equation numerically. It is found that the efficiency of a thermoelectric generator is insensitive to both the electrical resistivity and thermal conductivity. However, the efficiency ...

Thermoelectric effects in Kondo insulators are attracting interests because of the emerging possibility of developping better thermoelectric materials for a portable refrigerator without liquid coolant. In this article, the theory of thermoelectric effects are reinvestigated for insulators or semiconductors at low temperatures. It is found that the famous relations established by Lord Kelvin fo...

Boron-doped nanographite ensembles (NGEs) are interesting thermoelectric nanomaterials for high temperature applications. Rapid induction annealing and quenching has been applied to boron-doped NGEs using a relatively low-cost, highly reliable, laboratory built furnace to show that substantial improvements in thermoelectric power factors can be achieved using this methodology. Details of the de...

Thermoelectric properties of a model skyrmion crystal were theoretically investigated, and it was found that its large anomalous Hall conductivity, corresponding to large Chern numbers induced by its peculiar spin structure leads to a large transverse thermoelectric voltage through the anomalous Nernst effect. This implies the possibility of finding good thermoelectric materials among skyrmion ...

This paper aims to evaluate the ability of some well-known bio-inspired metaheuristics for optimal arrangement of thermoelectric cells mounted in a thermal component. In real life applications, proper arrangement of thermoelectric modules plays a pivotal role by maximising the generated electricity. However, some defects such as the increase in total maintenance cost is often associated with th...

Temperature drops at the interfaces between thermoelectric materials and the heat source and sink reduce the overall efficiency of thermoelectric systems. Nanostructured interfaces based on vertically aligned carbon nanotubes (CNTs) promise the combination of mechanical compliance and high thermal conductance required for thermoelectric modules, which are subjected to severe thermomechanical st...
