6 October 2014 Plasmonic electrodes for organic photovoltaics: polarization-independent absorption enhancement
Author Affiliations +
We systematically investigate the optical and electrical properties of ultrathin two-dimensional (2D) Ag nanogratings (NGs), and explore their use as plasmonic transparent conducting electrodes in molecular organic photovoltaics (OPVs). A large broadband and polarization-insensitive optical absorption enhancement in the CuPc (copper phthalocyanine): PTCBI (perylene tetracarboxylic bisbenzimidazole) active light-harvesting layers is demonstrated using ultrathin 2D Ag NGs, and is attributed to the excitation of surface plasmon resonances and plasmonic cavity modes.
