Organic inorganic halide perovskite-structured (OIHPS) materials emerge as promise next-generation optoelectronic materials. In particular, low-toxic methylammonium tin halides (CH3NH3SnX3; X=I, Br, Cl) exhibit strong electrical and tunable optical properties. The properties of a perovskite material strongly depend on the structural, morphology, selection of solvent and composition of the films. The state-of-the-art research efforts focused on CH3NH3SnX3 (X=I, Br, Cl) perovskite and these applications are thoroughly reviewed in this chapter. Furthermore, the enhancement of structural, morphology, optical, electrical and thermal properties of CH3NH3SnX3 (X=I, Br, Cl) perovskites was also discussed. We conclude by discussing the limitations and potential advancements of these CH3NH3SnX3 (X=I, Br, and Cl) perovskite materials.
