Abstract

Semi-transparent organic-inorganic hybrid photo-detector cells were fabricated on glass substrate, composed of pentacene/ZnO photodiodes and pentacene thin-film transistors (TFTs). Semi-transparent NiO_x window with a large band gap of ∼4 eV was used as an ohmic electrode on 50 nm-thin pentacene channel in the TFT and simultaneously on the 150 nm-thick pentacene layer, which is deposited on ZnO for p-n diode, to absorb visible and ultraviolet photons from pentacene and ZnO, respectively. Our photo-detector exhibited a minimum temporal response of ∼300 ms for photo-induced output voltage at -1 V input and -3 V supply voltage.
