In this study, we investigate effect of pseudo halide anionic molecules (MAF, MACOOH, SCN, MAN) on crystal growth of perovksite, MAPbI3. We conduct the analysis of SEM, AFM and XRD to figure out the crystal growth mechanism by adding pseudo halide anionic molecules. Finally, we demonstrate that MAN enable produce higher quality and larger crystalline domain of perovksite. We expect these findings will bring us improved photovoltaic performance due to less trap sites between grain boundaries.
