Conducting polymer thermoelectric material and process of making same

A process for making a thermoelectric material whose temperature decreases upon passing an electric current therethrough, comprising the steps of:

• combining a first solvent with poly-3-octylthiophene and ferric chloride, said poly-3-octylthiophene and said ferric chloride in a respective molar ratio of approximately 2:1;
• mixing said first solvent, said poly-3-octylthiophene and said ferric chloride for a first period of time during which said poly-3-octylthiophene and said ferric chloride are partially dissolved;
• combining a second solvent with said first solvent, said poly-3-octylthiophene and said ferric chloride for a second period of time during which said poly-3-octylthiophene with said ferric chloride completely dissolves;
• and
• removing said first and said second solvent wherein said poly-3-octylthiophene completely mixed with said ferric chloride forms said thermoelectric material.
