Gold (Au) nanoparticles are incorporated into the P3HT/PCBM active layer of organic solar cells in order to enhance their power conversion efficiency (PCE). In addition, a zinc oxide (ZnO) buffer layer was assembled on top of the P3HT/PCBM/Au-NPs active layer in order to increase the charge mobility across the cells. The incorporation of Au-NPs in the active layer and the addition of a ZnO buffer layer increased the power conversion efficiency by approximately 60%, compared to a reference cell without Au-NPs and a buffer layer. The short circuit current (J sc) of the cells containing 0.5 mg of Au-NPs and a ZnO buffer layer was measured at 7.381 mA/cm2 compared to 5.225 mA/cm2 in the reference cells; meanwhile, the external quantum efficiency (EQE) increased from 61.25% to 68.23%, showing an enhancement of 11.4%. Furthermore, Au-NPs improved the charge collection at the anode, which resulted in a higher short circuit current and fill factor. The strong near field around Au-NPs due to a localized surface plasmonic resonance (LSPR) effect enhanced the light absorption in the active layer, and hence the overall electrical performance of the cells.
