Space charge formation in the system with hopping ionic conductivity as the electric power generation at low temperature gradients

摘要

The hopping charge transfer in the ion-conductive 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 thermoelectric efficiency, the power conversion efficiency and conditions for the optimal application as a low temperature thermoelectric converter.
