## Description

- description: Ag2Se-based materials with promising room-temperature thermoelectric
    performance and excellent mechanical properties have been known for decades. However,
    the fabrication of the Ag2Se-based devices toward the practical application of
    electronic cooling has seldom been reported. Herein, the synthesis of Ag2Se material
    with a diameter of 25.4 mm was achieved. The homogeneous elemental distribution
    and similar thermoelectric properties demonstrate the high uniformity of the Ag2Se
    sample. In addition, ~90 Ag/Ag2Se/Ag legs can be obtained from a single Ag2Se
    plate, and the interfacial contact resistivity of the Ag/Ag2Se varies from 0.8
    to 3.1 μΩ cm2. Four thermoelectric devices based on n-type Ag2Se and p-type (Bi,
    Sb)2Te3 have been fabricated, and they achieve a cooling temperature difference
    of ~ 56 K at the hot-side temperature of 300 K, demonstrating the great potential
    of Ag2Se material for cooling applications.
