| description | Flexible Ag<sub>2</sub>Se thermoelectric (TE) films are promising for wearable applications near room temperature (RT). Herein, a Ag<sub>2</sub>Se film on a nylon membrane with high TE performance was fabricated by a facile method. First, Ag<sub>2</sub>Se powders were prepared by a microwave-assisted synthesis method using Ag nanowires as a template. Second, the Ag<sub>2</sub>Se powders were deposited onto nylon via vacuum filtration followed by hot pressing. Through modulating the Ag/Se molar ratio for synthesizing the Ag<sub>2</sub>Se powders, an optimized Ag<sub>2</sub>Se film demonstrates a high power factor of 1577.1 μW m<sup>−1</sup> K<sup>−2</sup> and good flexibility at RT. The flexibility of the Ag<sub>2</sub>Se film is mainly attributed to the flexible nylon membrane. In addition, a six-leg flexible TE generator (f-TEG) fabricated with the optimized Ag<sub>2</sub>Se film exhibits a maximum power density of 18.4 W m<sup>−2</sup> at a temperature difference of 29 K near RT. This work provides a new solution to prepare high-TE-performance flexible Ag<sub>2</sub>Se films for f-TEGs. |
