Specific features of the physical models of organic-fueled TEGs are considered. Comprehensive classification of thermogenerators is presented and techniques for improving their efficiency and expanding the field of their application are determined.
Review of theoretical methods for description of thermoelectrical properties of two-phase macroscopically inhomogeneous media is given. Description by means of a hierarchical model of percolation structure is given, allowing a description on a qualitative and quantitative level of the basic regularities of effective thermoelectric coefficient close to flow threshold.
Attempts have
been made in the past to specify an upper limit for the dimensionless thermoelectric figure of merit ZT. This limit has been placed between 1 and 4 according to the assumptions that have been made. For most of the half-
