Abstract: (1664 Views)
In order to reduce defects and improve the crystallinity of peroveskite layer, we introduce FAPbI3 as crystalline grains for controlling the growth of MAPbI3 crystals, so We will have a mixed peroveskite layer ( ) with the spin-coating method.
The electron microscope and X-ray diffraction pattern exhibit better crystallinity and larger grains for the mixed peroveskite layer than the MAPbI3 layer. The positive correlation between crystallization and FAPbI3 concentration indicates that the crystallization process is controlled by induction of FAPbI3. In this paper, we have tried to show the specification of this peroveskite in a complete cell by studying the uv-visible absorption spectrum and SEM and the XRD spectrum.
