 note = {We report that opaque electrodes can be used for high-performance organic optoelectronic devices, facilitated by the electric double layers (EDLs) formed in ionic liquids. For the photocell, gold/poly(3-hexylthiophene-2,5-diyl) (P3HT):[6,6]-phenyl C61 butyric acid methyl ester (PCBM)/ionic liquid/silver, the EDLs enable a large photocurrent response, without the electrodes being superimposed. The external quantum efficiency and responsivity can reach 61.2% and 272 mA/W, respectively. The specific detectivity can reach 1.9 × 1013 Jones, which is larger than silicon-based detectors. This type of architecture will renew the operation principle and material choice for organic photocells, because transparency is no longer an indispensable condition for the electrodes.},
