title: Photocurrent Enhancement of P3HT:PCBM Organic Solar Cell with Cylindrical Ag-NPs by EBM.
abstract: The power conversion efficiency (PCE) of
  PSS/P3HT:PCBM organic solar cells(SCs) with Ag nanoparticles (NPs) on ITO is studied, and the optical absorption of the SCs with a cylindrical Ag-NPs model is investigated. The fabricated device structure is simulated with a finite difference time domain (FDTD) method. This cylindrical Ag-NPs model is able to explain the photocurrent enhancement by the localized surface plasmon resonance (LSPR) modes, and to provide a further understanding of Ag-NPs shape parameters which play an important role to determine the broadband absorption phenomena in plasmonic organic solar cells. Compared with the SCs without Ag-NPs, an increase in the PCE of the plasmonic solar cell was accurately identified. The photocurrent-voltage characteristic of the examined solar cells reveals higher efficiency of 2.75% compared with the reference cells which show 1.67%.
