Plasmonics and organic photovoltaics(OPVs) fields are working together to improve the absorption of sunlight and the photon-electron coupling lift up the performance of devices. It is shown that a careful choice of size, concentration and location of Au NRs in the device result in an enhancement of the power conversion efficiencies when compared to standard organic solar cell devices.We have systematically explored how plasmonic effects influence the characteristics of OPVs in corporating a blend of poly[4,8-bis[(2-ethylhexyl)oxy]benzo[1,2-b:4,5-bA]dithiophene-2,6-diyl][3-fluoro-2-[(2-ethylhexyl)carbonyl]thieno[3,4-b]-thiophenediyl](PTB-7) and [6,6]phenylC71butyricacidmethylester (PC70BM). We studied the competition between energy loss due to quenching and enhanced absorption arising from the near-field plasmonic effect of Au NRson the performance of OPV, by fabricating inverted architecture OPV with active layers consisting of an Au NRs. |
