Hybrid-halide perovskite thin films for thermoelectric application

Thermoelectric effect can be a promising candidate as a sustainable energy source for internet of things devices. In this regards, thin films of organic-inorganic hybrid halide-perovskites, Methylamonium tin iodide, were fabricated by spin coating technique on a glass substrate. Thin films were structurally and chemically characterized by x-ray diffraction pattern and scanning electron microscope. Thermoelectric parameters were measured near room temperature. Thin films heated for 5 min at 100 degrees C shows the best performance with electrical conductivity 2.4 S/cm, Seebeck coefficient 65 mu V/K and power factor of 1.0 mu W/m.K-2. Thermoelectric performance from these hybrid-halide perovskite will help for further development of direct thermal energy harvesting devices near room temperature.
