| Abstract Scope |
Here, we present novel and scalable ink-based printing methods that enable high-throughput discovery of thermoelectric materials and scalable and low-cost device manufacturing. An aerosol based high-throughput combinatorial printing method is developed to accelerate the discovery of high-efficiency thermoelectric materials. Highly scalable and low-cost extrusion printing and screen-printing processes were applied to transform high-efficiency materials into high-performance devices. The thermoelectric power factor in our printed p-type materials reaches 3500 µW/mK2, which is by far the highest in printed TE materials. This results in highly competitive room temperature ZT of 1.3. A printed thermoelectric cooling device generates a maximum cooling temperature difference >75K when the hot side is maintained at room temperature. Moreover, the printed devices offer mechanical flexibility and adaptability to curved surfaces, making it advantageous for a much broader range of applications than the rigid bulk devices. |
