This letter reports a Pentacene and Er-doped ZnO (EZO) nanocomposite (NC) based wideband photodetector working in ultraviolet (UV), visible and a part of the near-infrared (NIR) regions. The proposed device consists of Al/Pentacene:EZO/PEDOT:PSS/Indium Tin Oxide (ITO) structure using a low-cost solution method. The Pentacene:EZO NC shows a wide absorption spectrum covering UV-visible-NIR regions. At a reverse bias of −1 V, the measured responsivity values (A/W) of the proposed device are 23.36, 18.41, and 206.97 at 300 nm (UV), 660 nm (visible) and 980nm (NIR), respectively. The reproducibility of the proposed structure is also analyzed in the letter.
