In this reaserch, using the finite difference time domain method (FDTD), the effect of the presence of solid aluminum nanocylinders and containing elliptical holes (cores) on the quantities of short-circuit current density and absorption has been investigated in the ITO/PEDOT:PSS/P3HT:PCBM/ZnO/Al organic solar cell. The nanoparticles are located in a hexagonal pattern inside the P3HT:PCBM layer and on the border with ZnO. The nanoparticles are located in a hexagonal pattern inside the P3HT:PCBM layer and on the border with the ZnO layer. For simulation, the standard spectral pattern of the sun AM1.5 has been used in the spectral range of 300-1200 nm. Calculations have shown that the presence of different nanocylinders causes a significant improvement in the values of high quantities. This is especially noticeable in the range of high wavelengths.In addition, the presence of nanocylinders creates an optimal thickness of 150 nm for the active layer of P3HT:PCBM solar cell, so mentioned quantities have the highest values. This optimal thickness is independent of the presence of dielectric cores in nanocylinders. Comparing the calculation results in different conditions shows that when the thickness of the active layer is 150 nm, the height and radius of the nanocylinders are 50 nm and 15 nm, and the elliptical holes have small and large radii of 1 nm and 15 nm, The short-circuit current density and absorption of the intended solar cell have their optimal values.
