“…The decreasing thickness values for film annealed at 400°C may be associated with surface morphology, decreased roughness, and perhaps manufacturing conditions. Other studies on this subject have revealed the smooth, and homogeneous nanoscale film surface morphology, and thickness obtained from SEM and TEM images [14,[40][41][42].…”

“…Among them, bilayer structures consisting of ZnO and Al2O3 layers have been attracting attention, recently [10][11][12][13]. Due to the optical properties like high transparency of ZnO and high specific surface area of Al2O3 layers, ZnO/Al2O3 bilayer/laminate films are especially useful for optical coatings [14,15]. ZnO/Al2O3 bilayer films and derivatives can be produced by many techniques such as chemical vapor deposition (CVD), atomic layer deposition (ALD), sol-gel dip coating, and ultrasonic spray pyrolysis (USP) techniques [16][17][18][19][20][21][22].…”

Impact of annealing on structural, morphological, elemental, and optical properties of bilayer ZnO/Al2O3 film has been investigated. Bilayer film has been deposited on microscope slides by ultrasonic spray pyrolysis method at 350°C substrate temperature. Then, this film has been annealed at 400°C, 500°C, and 600°C under atmospheric conditions, respectively. Structural analyses have been revealed that bilayer films have polycrystalline with hexagonal wurtzite structures of ZnO. Also, there is no other structures have been found like Zn-Al etc. Morphological and elemental analyses have been presented that the alterations of surface, and diffusions of Al to ZnO layer. Cross-sectional images have been revealed the film thickness between 0,78-1.56 m. Optical method have been used for calculation of optical band gap values of the films which are found between 3.17-3.25 eV. The results revealed that annealing leads to diffusion from the bottom layer Al2O3 of the material to the upper layer, ZnO. In addition, it was determined that the as-deposited ZnO/Al2O3 film is still leading in terms of the investigated properties.

In this study, the performance of activated carbon (AC) produced from defatted black cumin (Nigella Sativa L.) by chemical activation with zinc chloride (ZnCl 2 ) activator in photovoltaic application is evaluated. It is of great importance to increase the photovoltaic e ciency of cadmium sul de (CdS) based solar cells, which are widely used in photovoltaic applications, with AC support. The main purpose of the study is to determine how the incident photon-to-current conversion e ciency (IPCE) of undoped and Mo-doped AC supported CdS semiconductor materials changes in the presence of AC support material and to interpret the observed effect in the light of literature. For these reasons, in the study, AC supported CdS (CdS/AC) (5%, 10% and 15% by weight) and Mo-doped CdS/AC semiconductor materials with different molybdenum (Mo) concentrations (0.33%, 1%, 3%) are produced by chemical precipitation method. Produced CdS/AC and Mo-doped CdS/AC semiconductor materials are characterized by incident photon-to-current e ciency (IPCE), scanning electron microscopy (SEM), x-ray diffraction (XRD), energydispersive x-ray spectroscopy (EDX), and x-ray photoelectron spectroscopy (XPS) measurements. Based on the result values, the optimum CdS concentration with the highest IPCE (%) value is determined as 10% (for CdS/AC). As a result of the experimental measurements, the optimum Mo concentration with the maximum IPCE (%) value is found as 1% (for Mo-doped CdS/AC). In particular, it is clear that an appreciable increase (from 4.70% to 39.00%) in IPCE (%) of 1% Mo-doped 10% CdS/AC semiconductor material is achieved when compared to pure CdS.
