“…It was noteworthy that these lattice parameter values closely matched the standard lattice parameters listed in the IDSD (98-018-0051) file, which are a = b = 3.250 Å, and c = 5.211 Å. These results indicated a highly crystalline structure and excellent compatibility, particularly in the heterostructure [37]. The XRD pattern and variation results of n-TiO 2 /ZnO bilayer thin films at different spinning speeds are presented in Figure 6 and Table 2, respectively.…”

The spinning speed parameter plays a crucial role in determining the properties of an n-TiO2/ZnO bilayer thin film fabricated using the sol–gel spin-coating technique, especially for solar cell applications. In this study, various spinning speeds were employed on an n-TiO2/ZnO bilayer thin film, and characterizations were conducted, such as morphological, structural, and optical properties. The findings revealed that the optimal conditions for the thin film were achieved at a spinning speed of 3000 rpm. Under this condition, a homogenous and compact surface morphology was observed, with an even distribution of ZnO grains. The successful fabrication of an n-TiO2/ZnO bilayer thin film was confirmed by the presence of characteristic peaks for both TiO2 and ZnO. Obviously, three dominant ZnO orientation peaks, which included (100), (002), and (101) were identified. The prevalence of the (002)-ZnO orientation plane indicated a high-quality structure with excellent crystallinity. In terms of optical properties, the achievement of high transmittance up to 75% resembles the high transparency of the thin film. The optical energy of the n-TiO2/ZnO bilayer thin film is estimated at 3.10 eV. In summary, the spinning speed parameter played a pivotal role in enhancing various properties of the thin film, making it a significant factor in its development for diverse applications.

“…It is essential to minimize the lattice mismatch to ensure a proper Cu 2 O stacking process using the electrodeposition method. Therefore, the highoriented (002)-plane of ZnO is indispensable to overcome the lattice mismatch at the heterointerface [37].…”

“…Aside from inexpensive, Cu 2 O is also nontoxic, has good electron mobility and a fairly minor carrier diffusion length [10]. Since ZnO is hexagonal (wurtzite) and Cu 2 O is cubic (cuprite), both combination thin film layer exhibited a similar hexagonal atomic arrangement at the interface with 7.1% of lattice mismatch [11]. Electrodeposition method is the preferred technique for Cu 2 O deposition because it is economical for preparation of large area film with homogeneity.…”

Metal oxide semiconductor materials have shown a great potential in the fabrication of heterojunction thin film due to its improved properties for photovolatic mechanism in solar cell application. In this work, p-(111)-Cu 2 O based heterostructure was successfully developed with uniformity and highly oriented n-TiO 2 /(002)-ZnO bilayer thin film in order to overcome improper electron mobility between the heterointerface of n and p-type layer by optimizing several properties. n-TiO 2 /ZnO bilayer acts as window layer deposited on FTO substrate by using sol-gel spin coating method. The crystallize size and transmittance spectrum of n-TiO 2 thin film was improved after n-ZnO was coated onto TiO 2 thin film. Meanwhile, cyclic voltammetry (CV) measurement was carried out and potential deposition of −0.4 V vs Ag/Cl at 40 °C was acquired. p-Cu 2 O which acts as absorbing layer was deposited onto n-TiO 2 /ZnO bilayer by using electrodeposition technique. The successful fabrication of n-TiO 2 /ZnO/p-Cu 2 O heterostructure were confirmed by the existence of all peaks on the XRD spectrum. Two strong absorption edges observed and the merged shape of p-Cu 2 O grain with other layer leads to the surface flatness improvement. The optical energies of n-TiO 2 /ZnO bilayer and p-Cu 2 O thin film are estimated as 3.15 and 1.75 eV, respectively. The structural, morphological, optical, and topological properties of thin films were characterized using X-ray diffraction, Field emission-scanning electron microscope, Ultraviolet-visible spectroscopy, and Atomic force microscopy, respectively.
