▲ [8a-Z26-1] Enhancement of thermoelectric properties of hybrid-halide perovskites thin films using anti-solvent
Keywords:Hybrid Halide Perovskites, Thermoelectric, thin film coating
Thin films are fabricated by spin coating technique using a yellow precursor solution of MASnI3. The yellow solution is prepared by MAI, SnI2 precursors. During the fabrication process, we optimized growth parameters such as baking time and the presence of anti-solvent. MASnI3 thin films have shown p-type semiconducting behavior. MASnI3 thin films were thoroughly characterized using several state-of-the-art techniques including XRD and SEM. Temperature dependent Seebeck coefficient, electrical resistivity and thermal conductivity measurements were performed. MASnI3 thin films baked at 100°C for 5 min with anti-solvent shows the best result with Seebeck coefficient about 65 μV/K and electrical conductivity of about 2 S/cm near room temperature.
