Abstract:

 Methylammonium lead iodide MAPbI3 perovskite thin films, which were pure and ZnBr2-added at different rates 1, 3, and 5 wt, were deposited on fluorine-doped tin oxidetitanium dioxide FTOTiO2 substrates by the spin coating method. X-ray diffraction XRD analysis showed that the peak at 14 was the main peak for all thin films. A shift was observed with the addition of ZnBr2 at the main peak position. As the ZnBr2 addition rate increased, PbI2 peaks occurred at 12.5. It was seen in the scanning electron microscope SEM surface image that the grain sizes were larger than the others on the MAPbI3 perovskite thin film with 5 wt ZnBr2 added. For MAPbI3 perovskite thin films with 5 wt ZnBr2 added, the absorbance value in the visible region from 390 to 780 nm was higher than the others. It was observed that the band gap value Eg of MAPbI3 perovskite thin films can be adjusted by adding ZnBr2.
