Abstract
The paper presents the results of modeling and comparative analysis of the output parameters of thermoelectric generators with two types of geometry. The first is based on a Y-structure with a flexible substrate, the second is based on a P-structure with a flexible base. The results of modeling at different temperature conditions and the comparison of output parameters for the Y and P structures are presented. The following results were obtained: the maximum output power of the generator based on the Y-structure at ΔT = 22 K was Pmax = 14.3 μW, for the P-structure Pmax = 5.6 μW. The specific maximum output power for the Y-structure was Pmax / S = 0.54 μW / mm2, for the P-structure Pmax / S = 0.21 μW / mm2. Thus, a thermoelectric generator built on the basis of a Y-structure has a specific output power almost three times higher than that of a similar one with a P-structure.
