Hybrid perovskites have generated a great deal of interest because of their potential in photovoltaic applications. However, the toxicity of lead means that there is interest in finding a nontoxic substitute. Bulk single crystals of both cubic CH 3 NH 3 SnI 3 and CH(NH 2 ) 2 SnI 3 were obtained by using the top‐seeded solution growth method under an ambient atmosphere. Structural refinement, band gap, thermal properties, and XPS measurements of CH 3 NH 3 SnI 3 and CH(NH 2 ) 2 SnI 3 single crystals are also reported in detail. These results should pave the way for further applications of CH 3 NH 3 SnI 3 and CH(NH 2 ) 2 SnI 3 .
