“…These electrons along with the holes in the different sides of the polyaniline/ZnO NRs heterojunction, created the low width of the depletion region, which causes an eased carrier transport through the heterojunction. Thus, the as-fabricated UV photodetector exhibited improved performance compared with the pristine ZnO NRs-based UV photodetector [156].…”

Ultraviolet photodetectors have attracted significant research attention in recent years due to their potential applications in civilian and military fields. ZnO nanowires and nanorods have been regarded as the most potential candidates for ultraviolet photodetectors fabrication because of their peculiar characteristics and size effect, which are different from their bulk material. Recently, many novel routes and semiconductor features, such as the surface and interface engineering, the pryo-phototronic effect, the piezo-phototronic effect, the surface plasmon effect and the surface functionalization have been utilized to improve the photoelectric characteristics of ultraviolet photodetectors. Thus, the working mechanism of these effects existing in ZnO nanowires/nanorods-based ultraviolet photodetectors should be investigated in-depth. In this paper, firstly, the hydrothermal method and the chemical vapor deposition method, as two typical synthesis methods of ZnO nanowires are briefly reviewed. Secondly, we focus on reviewing the properties of varied ZnO nanowires/nanorods-based ultraviolet photodetectors constructed using the above mentioned semiconductor features with metal-semiconductor-metal structure, Schottky barrier structure, vertical p-n heterojunction structure and core-shell heterostructure. Furthermore, the most attractive self-powered ultraviolet photodetectors are systematically reviewed. For various ZnO nanowires/nanorods-based ultraviolet photodetectors, we put the emphasis on the working mechanism of semiconductor features to improve the properties of the photodetectors. Finally, we give an outlook on the future development of ZnO nanowires/nanorods-based ultraviolet photodetectors.

“…88 Moreover, a flexible self-powered UV PD was reported by Ghorbani et al, with n-ZnO and p-type polyaniline (PANI) nanocomposite. 120 Hydrothermal technique was utilized to grow ZnO NRs in the composite. In their technique, initially, sodium hydroxide (3.84 g) and cetyltrimethylammonium bromide (0.146 g) were dissolved in 50 ml distilled (DI) water and mixed for 3 hr at RT.…”

“…The hydrothermal process was then carried out by transferring the colloid into an autoclave (teflon lined) and subjected to 110 °C for 12 hr. 120 The sample obtained at the end of the process is then cleaned, dried (120 °C), and calcinated (600 °C) to finally obtain the ZnO NRs. A series of chemical route was then adopted for the synthesis of the nanocomposite.…”

“…The cleaned sample was then dried at 70 °C (dark green colour) and finally un-doped with ammonia (0.1 M) to form the ZnO/polyaniline nanocomposite base at RT. 120 Final steps then involved RT fusing of the nanocomposite base with 10-Camphor sulfonic acid (CSA) with further mixing with chloroform under fast rotation.…”

“…Values of 1.3 and 0.024 lA/W have been reported for On-Off ratio and photoresponsivity, respectively [10]. Flexible Ultraviolet zinc nanorods photodetectors are reported to show photoresponsivity within the range of 0.13-0.19 A/W under UV power density varying between 0.8 and 12.47 mWcm -2 [11]. ZnO films drop-cast on fluorine doped ITO substrates was coated with a layer of natural dye for hybrid photoelectrodes with improved performance [12].…”

Photoelectrochemical properties have been investigated for flexible photoelectrodes containing 310 nm thick ZnO film on spin-coated ITO/PET. The high crystalline structure of ZnO was studied using x-ray diffraction pattern. A value of 3.4 eV has been estimated for optical band gap from its absorption spectra. The flexible ZnO photoelectrode was demonstrated to generate photoelectrochemical current. The photocurrents are enhanced by 4% whereas flat-band potential is shifted by 8 V due to the illumination. Values of 1.022 and 0.714 AW−1 were found to be for photo switching and photoresponsivity, respectively. ZnO/ITO/PET can be used as a substrate for making flexible hybrid PEC devices to generate solar power and solar fuels.
