Halide organometallic perovskite has an important role in the efficiency increase of the solar cell. Thus in this work, we formed the basic nucleus of the organic perovskite, and we studied its morphological properties. The X-ray diffraction result shows that this compound is consistent, homogeneous, and has preferential orientation growth be at (100) plane, which means that the experimental conditions which we worked on were optimal. After adding both tin iodide and methylamine chloride in organic solvents (DMF and DMSO). Deposited this mixture by spray pyrolysis method at Specific temperature 120C°, on the glass substrate, a thin black layer formed; the result of X-ray diffraction on this latter layer showed that it is a spectrum of perovskite compound, which has preferential orientation growth be at (110) plane. Via optical proprieties, it found that has low gap energy of 1.78 eV, and transmittance of 1,6% furthermore it has a high absorption coefficient of 8.104 cm-1, in the visible domain. But it has a relatively high value of Auerbach energy 0.6 eV due to the crystal defects. So this compound could be an active layer in the solar cell.
