Recently, the lead-free perovskite system is more regarded as important. In lead-free system, Sn-based halide perovskite solar cells (PSCs) are more focused on. However, the oxidation of Sn2+ to Sn4+ under ambient air will lead to unstable. Here, hybrid tin‐based perovskite solar cells in a new series that incorporate a nonpolar organic cation, we discuss that effect of GASCN(Guanidinium thiocyanate), in varied proportions into the formamidinium (FA+) tin triiodide perovskite (FASnI3) crystal structure in the presence of PEAI(2‐phenylethylammonium iodide) are reported.  We report the photoelectric properties about GASCN-doped hybrid organic perovskite is compared with three dimension FASnI3 perovskite.
