Title : Improved Perovskite Life Time by Using Nano Polymer Matrix Sandwich Structure
The stability of Perovskite materials lifetime by using Nano-polymer sandwich structure is investigated. A Perovskite composite is used consisting of the structure FAxMA1-xPbI3. The x ratios varied as 0.8,0.5 and 0.2. Two different polymers are used namely PMMA and Polyaniline. The polymer's thicknesses were varied by using a spin coating method before and after the deposition of the Perovskite structure. X-ray diffraction and Uv-Vis-Nir spectroscopy are used for the analysis of the lifetime. Thus far over 75 days, material lifetime is observed without any noticeable decomposition of the Perovskite layer, when compared to a reference sample. The study is performed at room temperature and open atmosphere without any special equipment to preserve the Perovskite from degradation.
