Thermoelectric effect can convert thermal energy into electricity without any moving parts or vibrations in light or dark. These can be promising advantages to develop sustainable energy source for internet of things devices. In this regards, thin films of hybrid-halide perovskites, methylamonium tin iodide, were fabricated by spin coating technique on a glass substrate at different annealing times. Thin films were structurally and chemically characterized by x-ray diffraction pattern and a scanning electron microscope. Thermoelectric parameters were measured near room temperature. During optimization, thin films annealed for 5 min at 100°C shows the high performance with electrical conductivity 3.56 S/cm, Seebeck coefficient 66.03 μV/K and power factor of 1.55 μW/m K² at 50°C. Thermoelectric performance from these hybrid-halide perovskite will help for further development of direct thermal energy harvesting devices near room temperature.

热电效应可以将热能转化为电能，而无任何活动部件或在明暗环境中振动。这些可能为开发物联网设备的可持续能源提供有希望的优势。在这方面，通过旋涂技术在不同的退火时间下在玻璃基板上制备了杂卤化物钙钛矿的薄膜，碘化甲基铵锡。通过X射线衍射图和扫描电子显微镜对薄膜进行结构和化学表征。在室温附近测量热电参数。在优化过程中，在100°C退火5分钟的薄膜表现出很高的性能，电导率为3.56 S / cm，塞贝克系数为66.03μV/ K，功率因数为1.55μW/ m K ²在50°C下。这些杂化卤化物钙钛矿的热电性能将有助于进一步开发接近室温的直接热能收集装置。
