“…In our previous studies, we have developed nanostructured ZnO on flexible ITO/PET substrates via sol-gel, spin coating and HWT method at low temperature, investigating the effect of time exposure of wet oxidation and sol-gel concentration [1,2,34]. HWT method is done by immersing coated substrates into hot water at respected time and surrounding pressure [1]. Meanwhile…”

In this paper, a review on the structural and morphological of nanostructured zinc oxide (ZnO) fabricated on flexible conductive substrate, mainly indium tin oxide coated on polyethylene terephthalate (ITO/PET) via various fabrication method is reported. Besides fabrication method, the effect of fabrication condition such as immersion time of ZnO-ITO/PET via hydrothermal method, concentration of modification material of precursor solution via sol-gel method, value of applied cathodic voltage and value of current densities via electrochemical deposition are also discussed. XRD analysis showed that the growth of ZnO-ITO/PET are preferred on (002) or (101) planes. SEM analysis revealed various type of nanostructured ZnO when prepared by sol-gel, spin coating, HWT and hydrothermal method, highlighting ZnO nanorods as the main morphology of ZnO-ITO/PET. The diameter of ZnO nanorods ranges from 10 nm to 830 nm.

“…Moreover, indium doped tin oxide (ITO)‐coated thin film layer can be used as a buffer layer to reduce the residual stress and structural defects in the film, that is why ITO‐coated PET substrate is suitable to deposit Al doped ZnO (AZO) films. [ 15,16 ] AZO thin film has been deposited by various techniques, such as sol–gel, pulse laser deposition, atomic layer deposition, and radio frequency (RF) magnetron sputtering. [ 17–20 ] Among these techniques, magnetron sputtering is most utilized due to better adhesion, parameter controllability, and high deposition rate than other methods.…”

In the present work, fixed Al (2.5 wt%) doped zinc oxide (ZnO) thin films are fabricated at different radio frequency (RF) power on indium doped tin oxide‐coated polyethylene terephthalate substrate by sputtering techniques. From the X‐ray diffraction (XRD) results it has been observed that all thin films have polycrystalline nature with hexagonal structure. Stress of thin film calculated from XRD measurement is increased from −0.10 × 109 to 0.23 × 109 N m−2 with increase in RF sputtering power. The morphology analyzed by field electron microscopy is observed as irregular sphere for all samples. The estimated values of thickness are 440, 870, 913, and 1086 nm for the films grown at RF sputtering powers 130, 140, 150, and 160 W, respectively. On increasing the RF power from 130 to 160 W, the optical bandgap is decreased from 3.59 to 3.48 eV. The highest conductivity obtained is 2.43 × 102 S m−1 for the sample grown at sputtering power 160 W. The study reveals that there is an impact of sputtering power on the various properties of thin films grown on flexible substrates and these films have wide applications in flexible electro‐optical applications.

“…There are several conventional fabrication techniques to synthesis ZnO nanorods such as thermal evaporation, chemical vapor deposition (CVD) and cyclic feeding CVD, sol-gel deposition, electrochemical deposition, hydrothermal and solvo-thermal growth, surfactant and capping agentsassisted [23,37,38] However, most of the synthesis methods are expansive, , complicated, nonscalable, environmentally hazardous and required well-trained and experienced operators [39][40][41] Therefore, it is crucial to have a simple fabrication method that can overcome most of the ZnO nanorods growth related issues. A simple hot water treatment (HWT) process has been recently demonstrated to produce metal oxide nanostructures on different metal surfaces [41].…”

Zinc-oxide (ZnO) nanostructures including nanorods are currently considered as a pioneer research of interest world-wide due to their excellent application potentials in various applied fields especially for the improvement of energy harvesting photovoltaic solar cells (PSC). We report on the growth and morphological properties of zinc-oxide (ZnO) nanorods grown on the surface of plain zinc (non-etched and chemically etched) plates by using a simple, economical, and environment-friendly technique. We apply hot water treatment (HWT) technique to grow the ZnO nanorods and varies the process parameters, such as temperature and the process time duration. The morphological, and elemental analysis confirm the agglomeration of multiple ZnO nanorods with its proper stoichiometry. The obtained nanostructures for different temperatures with different time duration showed the variation in uniformity, density, thickness and nanonorods size. The ZnO nanorods produced on the etched zinc surface were found thicker and uniform as compared to those grown on the non-etched zinc surface. This chemically etched Zinc plates preparation can be an easy solution to grow ZnO nanorods with high density and uniformity suitable for PSC applications such as to enhance the energy conversion efficiency of the photovoltaic (PV) solar cells towards the future sustainable green earth.
