Abstract Scope |
Thermoelectric devices offer great opportunities in direct conversion of waste heat into electricity and solid-state refrigeration with no moving parts. To realize its broad applications in energy harvesting and thermal management, significant advances are required to not only increase thermoelectric figure of merit zT but also improve the mechanical flexibility and reduce the manufacturing time and cost. Here, we present a novel and versatile aerosol based combinatorial printing method that enables high-throughput discovery of thermoelectric materials of high figure of merit ZT. In addition, we demonstrate a machine learning assisted high-throughput printing and ultrafast photonic flash processing method that produces silver selenide based flexible films with room temperature ZT > 1, which is among the highest in flexible thermoelectric materials. The high-throughput and scalable additive manufacturing and sintering methods offer efficient and low-cost manufacturing process for high-performance and flexible thermoelectric devices and a broad range of energy and electronic materials. |
