Description
We report on a thermal stability of Perovskite solar cells precursors (CH3NH3I and PbI2) synthesized following a simple precipitate method. The structure, morphology, mass loss behavior, thermal behavior and thermal stability of these materials were investigated using X-ray diraction (XRD), Scannig electron microscpoe (SEM), Dierential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FTIR)
and Thermogravimetric analysis (TGA), respectively. XRD measurements indicated the presence of both organic and inorganic materials. SEM analyses revealed that both materials have similar morphologies that makes it compatible to work as a loyal active layer. TGA analysis suggested that both CH3NH3I and PbI2
components are stable at temperatures up to 244 degrees celsius and 500 degrees celsius, respectively. The various functional groups present both CH3NH3I and PbI2 components were identified by FTIR analysis
