Zusammenfassung:[Display omitted] •Novel fabrication of UV-PD based on flexible ZnO NRs/PPC using CBD.•ZnO NRs array have a uniform distribution with length of 1.96 μm.•The maximum value of ƞ is 550.7 under UV illumination of 385 nm at 15 V. This report involves a novel fabrication of ultraviolet (UV) photodetector (PD) based on ZnO nanorods (NRs) onto flexible polypropylene carbonate (PPC) substrate, ZnO/PPC, using chemical bath deposition (CBD). The structural, morphological and optical properties of the samples were studied by utilizing X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy dispersive X-ray spectra (EDX), and UV–Vis spectrophotometer. The photosensitivity values of the ZnO/PPC PD were determined to be 52.48, 47.46, and 42.53 toward wavelength of 385 nm at bias voltage of 5, 10 and 15 V, respectively. The response and the recovery times were good value when ZnO/PPC (PD) illuminated under ON/OFF UV pulse of 375, 385 and 405 nm at 5, 10, and 15 V bias voltages. The maximum values of the current gain and the quantum efficiency (ƞ), are 1.52 and 550.7 under UV illumination of 385 nm at 5 V and 15 V, respectively.
