This paper represents perovskite material based hybrid (ITO/ZnO-ZnMgO (nano)/PCBM/CH3NH 3PbI3-xClx/PEDOT: PSS/C3-SAM/Ag) organic solar cell with high quantum and power conversion efficiency. Due to the insertion of 3-aminopropanoic acid as an ambipolar self-assembled monolayer (C3-SAM) and ZnO/ZnMgO layer carrier collection efficiency increases. An optical modified structure is proposed (through the modification of ZnO/ZnMgO layer) to increase the surface to volume ratio and enhance the photon collection efficiency. As a result, the Internal quantum efficiency (IQE) increases 83.2% to 91.7% fill factor (FF) changes from 77% to 85%, short circuit current density (J(SC)) changes from 14.9 mA/cm(2) to 21 mA/cm(2), and overall solar cell efficiency increases from 9.17 to 14.7%.
