Abstract

The direct conversion of thermal energy into electricity is possible by thermoelectric effect. CsSnI3 perovskite has shown a way with its intrinsic ultralow thermal conductivity and large Seebeck coefficient. In this work, CsSnI3 thin films were optimized. Thin films were structurally and chemically characterized using X-ray diffraction (XRD) and scanning electron microscope (SEM). Thermoelectric properties such as electrical conductivity, Seebeck coefficient, and thermal conductivity were measured near room temperature (300 K). CsSnI3 thin films unileg thermoelectric modules were fabricated on a glass substrate. The maximum output power is obtained about 0.8 nW for five legs (25 mm × 3 mm × 600 nm) modules for the temperature difference of about 5 °C.
