A methodology for exact assurance of the warm conductivity of novel sans lead perovskite slight movies by 3ω strategy, acknowledged with a field programmable simple cluster circuit, is introduced. The target of the work is to concentrate on the connection between the warm conductivity of the photoelectric perovskites and the warm solidness of the sun oriented cells, in which they are consolidated. It is found that the sun powered cells' drawn out strength under various double-dealing conditions, like persistent brightening and raised temperatures, is impacted to an alternate degree, as per the warm conductivity. The created arrangement for execution of the 3ω strategy is adjusted for dainty film tests and can be applied to all layers engaged with the sunlight based cell, in this manner characterizing their singular commitment to the general gadget warm corruption. As indicated by the led estimations, the coefficients of warm conductivity for the original materials are as per the following: for the iodine-based perovskite film, it is 0.14 W/mK and for the chlorine-based perovskite film, it is 0.084 W/mK. Subsequently, the warm flimsiness and corruption rate at constant brightening are, individually, 10.6% and 200 nV/min for the iodine-based perovskite sun oriented cell, and 6.5% and 20 nV/min for the chlorine-based cell. At raised temperatures up to 54°C, the relating shakiness values are 15 μV/°C with a debasement pace of a normal of 2.2 μV/ min for the cell with iodine-containing perovskite and 300 nV/°C with a corruption pace of 66 nV/min for the cell with chlorine containing perovskite.
