From a physical electronic viewpoint, thermionic energy conversion is the direct production of electric power from heat by thermionic electron emission.

From a thermodynamic viewpoint, it is the use of electron vapor as the working fluid in a power-producing cycle. A thermionic converter consists of a hot emitter electrode from which electrons. The heat is proportional to both the electric current and the temperature gradient.

This is known as Thomson effect. Thermoelectric effect The thermoelectric effect, is the direct conversion of heat differentials to electric voltage and vice versa 6.

Solar energy is one of the most promising energy resources on Earth and in space, because it is clean and inexhaustible.

Therefore, we have been developing a solar-powered high-efficiency thermionic/thermoelectric conversion system which combines a thermionic converter (TIC) with a thermoelectric converter (TEC) to use thermal energy efficiently and to achieve high Cited by: Thermoelectric Materials: Advances and Applications - CRC Press Book Environmental and economic concerns have significantly spurred the search for novel, high-performance thermoelectric materials for energy conversion in small.

The book is aimed at readers with batchelor-level technical training, engineers, physicists or chemists, who are interested in learning more about the design of thermoelectric materials and devices.

Thermoelectricity is an all-solid-state energy conversion technology, which directly converts heat to electricity or electrical current to cooling /5(3). Thermoelectric materials show the thermoelectric effect in a strong or convenient form. The thermoelectric effect refers to phenomena by which either a temperature difference creates an electric potential or an electric potential creates a temperature difference.

These phenomena are known more specifically as the Seebeck effect (creating a voltage from temperature. Thermoelectric Conversion Systems Ltd Unit 5, Baird Court, 10 North Avenue, Clydebank Business Park Glasgow G81 2QP.

Brief History of Thermionic Conversion T h e earliest known thermionic energy conversion was given by Schlicter in (15). He showed (neglecting space charge and assuming +a = c&) that the vacuum converter at maximum power output yields a current density of J at a voltage of kTc/e, where J is the zero-field cathode.
