Abstract
An ultraviolet (UV) photosensor is successfully fabricated via heterojunction device consisted of n-type titanium dioxide (TiO2) nanorod arrays (TNAs), and p-type polyaniline (PANI) by a facile method on fluorine tin oxide (FTO)-coated glass substrate. The fabricated UV photosensor demonstrated a UV-catalyst activity through the generation of photocurrent under UV irradiation (365 nm, 750 µW/cm2). The measured UV response showed the highest generation of photocurrent of 0.52 μAcm-2, and responsivity of 0.65 mA/W at 1.0 V reverse bias. The results indicate that the fabricated TNAs/PANI heterojunction-based device could be a promising candidate for the application of UV photosensor.
