In this study, we investigate the absorbed light enhancement of various tandem architectures: mechanically stacked (four-terminal) and monolithically integrated (two-terminal) tandem solar cell, consisting of a methyl ammonium lead triiodide (CH3NH3PbI3) perovskite top solar cell and a Si bottom solar cell. The finite difference time domain (FDTD) method at the wavelengths of 400 to 1100 nm was utilized. Different radii, different center to center distances between two adjacent silver nanoparticles, as well as different positions of the nanostructured array in the active layer were investigated to achieve light absorption enhancement. The plasmonic resonance from the periodic array enhanced light absorption at intermediate and higher wavelengths. The maximum light absorption enhancement occurred at the wavelengths between 880 and 1050 nm. An array of silver nanoparticles with the radius of 80 nm and center to center distance of 180 nm shows the maximum light absorption enhancement due to the near field of the silver nanoparticles. The absorbed light power of two- and four-terminal tandem solar cells were calculated 16% and 24%, respectively
