Title : Improved perovskite life time by using nano-polymer matrix sandwich structure


The stability of Perovskite materials life time 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 polymers 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 life time. Thus far over 75 days material life time 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.

Audience take-away:

  • This study shows new methods of preserving the lifetime of Perovskite structures without decomposition.
  • Perovskite structures are widely investigated due to their importance in the photovoltaic applications. Yet most Perovskite structures faces decomposition after few hours or few days. Hence this research is showing long life time without any Perovskite decomposition due to the suggested structure.
  • This research is part of team work consists of several previous and new masters students working on the Perovskite structure design and investigation to greatly enhance the life time of this material.
