Fully inkjet-printed Ag₂Se flexible thermoelectric devices for sustainable power generation.

ABSTRACT: Flexible thermoelectric devices show great promise as sustainable power units for the exponentially increasing self-powered wearable electronics and ultra-widely distributed wireless sensor networks. While exciting proof-of-concept demonstrations have been reported, their large-scale implementation is impeded by unsatisfactory device performance and costly device fabrication techniques. Here, we develop Ag₂Se-based thermoelectric films and flexible devices via inkjet printing. Large-area patterned arrays with microscale resolution are obtained in a dimensionally controlled manner by manipulating ink formulations and tuning printing parameters. Printed Ag₂Se-based films exhibit (00 l)-textured feature, and an exceptional power factor (1097 μWm^-1K^-2
