Printed thermoelectric generators

Abstract

Článek popisuje možnosti získávání energie pomocí termoelektrických generatorů. Protože termoelektrické generátory mají velmi nízké výstupní napětí potřebují integraci velkého počtu jednotlivých termočlánků. Tiskové technologie umožňují zvýšit efektivnost výroby s jednotlivými články zapojenými do série. Laterální uspořádání termočlánků umožňuje snadný způsob tisku, ale účinnost je snížena velkým odporem dlouhých přívodů. V případě vertikálního uspořádání článků je celkový odpor menší, ale účinnost je omezena tepelnou vodivostí použitých materiálů. Kombinovaná konstrukce s bočním uspořádáním krátkých vývodů termočlánku umístěných v dvojvrstvovém tepelném izolátoru a tepelným tokem kolmým na matrici termočlánků spojuje výhody obou typů. ; The paper describes the possibilities of energy harvesting using thermoelectric generators. Because of very low output voltage thermoelectric generators need integration of large number of individual thermo-junctions. Printing technologies enhance effective production with individual junctions all connected in series. Lateral structure require an easy process to print nevertheless it suffers from the internal resistance of the thermoelectric materials. In case of vertical design, the total resistance is smaller but the efficiency is limited by thermal conductivity of used materials. A combined structure with lateral arrangement of short thermo-coupler legs placed in double-layer of thermal insulator and the heat flow perpendicular to the thermo-coupler matrix brings together advantages of both types.
