Abstract

•We demonstrated an organic photodetector with MoO3/Ag/MoO3 transparent electrode.•The DMD electrode showed max. transmittance of 85.7% with Rsheet = 6.2 Ω/sq.•Optical simulation and experimental measurement are conducted on OPD.•The top MoO3 layer allows direct deposition of scintillator material over OPD.•The methodology can be beneficial for low-cost, facile integration of photodetectors.

The top illuminated organic photodetectors (OPDs) with a Dielectric/Metal/Dielectric (DMD) transparent anode are fabricated. The transparent electrode is composed of molybdenum trioxide (MoO3)/silver (Ag)/MoO3 layers and zinc oxide (ZnO)/aluminum (Al) is used for bottom cathode. The optimized DMD electrode has an optical transmittance of 85.7% at the wavelength of 546 nm and sheet resistance of ∼6 Ω/sq. The fabricated OPDs exhibit a high detectivity and wide range linearity.
