Abstract	Thermoelectrics is gaining increased attention as a renewable direct energy conversion method from heat to electricity. The most efficient and up-to-date thermoelectric materials for temperatures of up to 250°C are (Bi$_{1−x }$Sb$_{ x }$)$_{2}$ (Te$_{1−y }$Se$_{ y }$)$_{3}$ alloys. In the current research, to discover practical thermoelectric power generation devices capable of operation at such temperatures, Bi$_{0.82}$Sb$_{0.18}$ alloy was considered as a lead-free high-temperature (<250°C) solder composition for bonding of n-type Bi$_{2}$Te$_{2.4}$Se$_{0.6}$ and p-type Bi$_{0.4}$Sb$_{1.6}$Te$_{3}$ legs into Cu, Ag, Ni and Fe metallic bridges. In the case of Cu, fine contacts with low electrical contact resistance of ∼1.5 ± 0.5 mΩ mm$^{2}$ were observed upon soldering at 350°C.
