Versatile polymer-coated Ag₂Se thermoelectric materials and devices for multi-scenario applications developed by direct-ink printing.

ABSTRACT: Flexible thermoelectrics offer eco-friendly solutions for wearable health monitoring, smart sensors, and energy harvesting. However, challenges remain in device fabrication and performance enhancement. Herein, flexible thermoelectric films-Ag₂Se/methylcellulose, poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)@Ag₂Se/methylcellulose, and polyvinylpyrrolidone@Ag₂Se/methylcellulose-are fabricated via a scalable and economical direct-ink printing method. After cold pressing and annealing, the polyvinylpyrrolidone@Ag₂Se/methylcellulose film shows a record-high power factor of 2191.5 μWm^-1K^-2 at 400 K among all the flexible organic/inorganic films prepared via direct-ink printing. The heterointerfaces, pores, boundaries, an
