The researchers — who are based at the Institute of Science and Technology Austria — printed p-type and n-type thermoelectric legs using colloidal suspensions as inks. The ink formulation was tailored to facilitate the formation of interfacial bonding between the solid particles during the removal of the liquid media. At room temperature, printed p-type bismuth antimony telluride ((Bi,Sb)2Te3) achieved a figure of merit, zT, value of 1.42, whereas n-type silver selenide (Ag2Se) achieved a value of 1.3. Printed thermoelectric legs were then assembled into a 32-pair device, demonstrating a cooling temperature gradient of 50 °C when the hot side was fixed at 30 °C in air. A cooling coefficient of performance of 3.8 was achieved with an applied current of 0.15 A at room temperature.
