Abstract

In this paper, 2-D ordered Ag, Au, and Cu nanoplasmonic structures were designed to enhance the absorption of P3HT:PCBM using transfer-matrix method and dipole-coupling model. Two degenerate transverse plasmon modes were found and supported by a coupled metal nanoparticle array embedded in P3HT:PCBM. In the inverted organic photovoltaic, Cu nanoplasmonic structure increased the absorption by 22.1% in visible range. In addition, nanoplasmonic structure provided a wide-angle absorption enhancement for both p and s polarized waves.
