XRD and SEM characterizations suggest that compact and uniform films with large grain sizes and high crystallinity can be obtained utilizing PbI"2. The power conversion efficiency of the FTO/compact-TiO"2/MAPbBr"3/Spiro-OMeTAD/Ag device increased from 5.3% to 7.6% after changing the PbBr"2 ...
Perovskite films were characterized by XRD, UV-Vis, SEM, AFM, PESA and Kelvin probe. The results show a cubic structure perovskite (XRD), band gap of 2.28 eV (UV-Vis), 3 mu m thickness and uniform grain distribution (SEM), roughness reduction from 118 nm to 6 nm (AFM), valence ...

SEM and AFM images revealed that grains for the pure sample are highly compact linked with each other with sharp grain boundaries but their size increased when doped with 4AMP. A direct bandgap of 2.341eV is noticed for pristine which is slightly decreased to 2.311eV as a result of doping....
