Abstract

Dielectric/metal/dielectric (DMD) electrodes have the potential to significantly increase the absorption efficiency and photocurrent in flexible organic solar cells. We demonstrate that this enhancement is attributed to a broadband cavity resonance. Silver-based semitransparent DMD electrodes with sheet resistances below 10 ohm/sq. are fabricated on flexible polyethylene terephthalate (PET) substrates in a high-throughput roll-to-roll sputtering tool. We carefully study the effect of the semitransparent DMD electrode (here composed of Zn_xSn_yO_z/Ag/In_xSn _yO_z) on the optical device performance of a copper phthalocyanine (CuPc)/fullerene (C₆₀) bilayer cell and illustrate that a resonant cavity enhanced light trapping effect dominates the optical behavior of the device.
