Abstract
Doping of thermoelectric materials with various additives is a promising approach for increasing the functional efficiency of thermoelectric materials of different classes. This paper presents preliminary results of studying the impact of the strontium borate dopant Sr(BO2)2 on the power factor (PF) of the oxide thermoelectric Bi2Sr2Co1.8Oy. Samples with the nominal composition Bi2Sr2–x[Sr(BO2)2]xCo1.8Oy, x = 0–0.15, were prepared by the solid-phase reaction method. The temperature dependences of the resistivity and Seebeck coefficient were measured, and the power factor of the synthesized materials was calculated. The results obtained show that doping with strontium borate enhances the power factor of Bi2Sr2Co1.8Oy thermoelectric.
