• Abstract Tin selenide (SnSe) has thermoelectric (TE) and photovoltaic (PV) applications due to its exceptional advantages, such as the remarkable figure of merit (ZT ≈ 2.6 at 923 K) and excellent optoelectronic properties. In addition, SnSe is nontoxic, inexpensive, and relatively abundant. These aspects

• -based binary chalcogenide SnX alloys (X = S, Se, and Te), the tin selenide (SnSe) compound belongs to the IV–VI semiconductor family and is the most studied TE material [1][5][31][32][33][34]. Tin selenide consists of economical, Earth-abundant, and nontoxic elements and has potential applications in

• selenide (SnSe); Introduction Thermoelectric (TE) materials convert the direct and reversible heat energy into electrical energy and offer a probable solution and feasible route for power generation alternatives as well as refrigeration through the accumulation of waste heat [1][2][3] or solar energy [4
