This study aims the preparation of stable Sn-based perovskite compounds for photovoltaic application. In our previous research, we found that the stability of Sn-based two-dimensional perovskite with p-fluorobenzylamine is higher than that with benzylamine. In this study, we prepared quasi-two-dimensional perovskite which has suitable absorption and stability for photovoltaic solar cells by increasing the inorganic sheet number. From the X-ray diffraction, formation of bilayer structure was confirmed and red-shift of absorption was observed.
