Methyl-ammonium lead tri iodide (CH3NH3PbI3) perovskite thin films have been prepared by solution processing. Thin film after deposited in the laboratory ambient conditions by drop casting, it prepared by two step method PbI2 and CH3NH3I at the glass substrate. The analysis provides: the absorption coefficient, extinction coefficient, refractive indices, real and imaginary components of the dielectric constant of the CH3 NH3 PbI3 films, energy gap. Energy gap of perovskite thin films is reached 1.8 that is very important for solar cell application.
