Perovskites have been investigated a lot by present and reported with outstanding optoelectronic properties. However, so far there is no publications about another important property, the electro-optical (EO) effect which is related to important applications in photolithography. This thesis is mainly mean to calculate the EO constants of one kind of organic perovskite material, CH3NH3PbI3, which has been reported to have good capability of forming film by spin-coating, through the way of putting the film of CH3NH3PbI3 between two layers of metal mirrors to build a Fabry-Perot interferometer and characterizing both the transmission in different positions with different incident angles and the response voltaic difference when electric field is applied to the sample to calculate the phase difference and the EO constant r31 and r33 for the assumption that the perovskite crystal grown naturally in spin-coating has the symmetry of C∞ and is polarized in the direction of its axis.
