The high-performance top electrode with a transmittance of 88.05% at 550 nm and a sheet resistance of 5.93 Ω sq-1 reached an extremely high figure of merit (σdc/σopt = 484). Incorporating plasmonic-assisted electrodes into a poly(3-hexylthiophene):[6,6]-phenyl-C61-butyric acid methyl ester (P3HT:PC61BM) blend system increased the cell efficiency from 2.91% to 3.35% compared with devices using a planar back electrode. We attributed the efficiency enhancement to the substantial scattering of back-reflected light and enhanced near-field absorption in the proximity of nanoholes. © The Royal Society of Chemistry 2015. |
