Outline of Final Research Achievements

To reduce the consumption of energy resources and prevent the emission of global warming gasses, thermoelectric conversion technique has been attracted much attention as a clean power generation system. In this study, we focused on molecular organic compounds as a thermoelectric material. Pentacene, tetrathiafulvalene-tetrachianoquinodimethane (TTF-TCNQ), and TTF-Ix thin films were fabricated and their thermoelectric properties were measured. In addition, we evaluated electric power generated from these organic thin films by measuring current-voltage characteristics.
