Sol–Gel Synthesis of Ca2.5Ag0.3Sm0.2Co4O9 Semiconducting Materials for Thermoelectric Applications in Aerospace Systems

Advanced Engineering Materials, EarlyView.
Ca2.5Ag0.3Sm0.2Co4O9 semiconductor materials are synthesized and produced in this study using the sol–gel and cold pressing techniques for thermoelectric generator applications. As template samples are added, the Seebeck coefficient and power factor values rise, peaking at 800 °C for Ca2.5Ag0.3Sm0.2Co4O9 at 274.47 μV K−1 and 0.58 mW mK−2, respectively.
