“…Recently, the low-cost, less energy-consuming (thermodynamically closed system) Duran laboratory bottle has been utilized as an alternative to the open beaker for CBD processes [18]. Moreover, several materials have been used as substrates in the CBD process, such as glass, p-type silicon, and n-type silicon [19][20][21][22]. However, using polytetrafluoroethylene (PTFE), or so-called Teflon, as a substrate in a closed growth system is rarely reported.…”

Developing non-toxic, semiconductor-doped heterojunction materials for optoelectronic applications on the surface of a flexible substrate is a viable strategy for meeting the world’s energy needs without introducing any environmental issues. In this paper, Ti:TiO2/ZnO nanocomposites were prepared by heat treatment and utilized as an active layer in UV photodetectors. First, a ZnO seed layer was deposited by radio frequency (RF) sputtering on polytetrafluoroethylene (PTFE) substrates. Then, TiO2/ZnO thin films (TFs) were successfully grown by combining volumetric mixtures of TiO2 and ZnO at the ratios of 1:7, 1:3, 3:5, and 1:1 via the chemical bath deposition (CBD) method. The morphological, elemental, and topographical analyses of the grown TFs were investigated through SESEM, EDX, and AFM spectroscopy, respectively. XRD patterns illustrated the presence of the unified (002) peak of the Ti/ZnO hexagonal wurtzite structure in all prepared samples, with intensities indicating a very strong preferential crystallinity with increasing TiO2 ratios. Enhanced diffuse reflectance curves were obtained by UV–Vis spectroscopy, with allowed indirect energy bandgaps ranging from 3.17 eV to 3.23 eV. FTIR characterization revealed wider phonon vibration ranges indicating the presence of Ti–O and Zn–O bonds. Metal–semiconductor–metal (MSM) UV photodetectors were fabricated by thermally evaporating Ag electrodes on the grown nanocomposites. The volumetric ratio of TiO2/ZnO impacted the photodetector performance, where the responsivity, photosensitivity, gain, detectivity, rise time, and decay time of 0.495 AW−1, 247.14%, 3.47, 3.68 × 108 jones, 0.63 s, and 0.99 s, respectively, were recorded at a ratio of 1:1 (TiO2:ZnO). Based on the results, the heterostructure nanocomposites grown on PTFE substrates are believed to be highly promising TF for flexible electronics.

“…As bangaps of CuO/Cu 2 O depend strongly on the deposition method, it is worth noting that it may take values from the range 1.0–2.1 eV for CuO [ 28 , 29 , 30 , 31 , 32 ] and 1.82–2.2 eV [ 33 , 34 , 35 , 36 ] for Cu 2 O, respectively. In our research, for CuO structure, we received values from the range 1.02–1.28 [ 37 ]. As in the case of multi-layer solar cells, there appears a lattice mismatch according to the materials applied [ 38 , 39 ]; in our analysis, we obtained a lattice mismatch between TiO 2 and Cu 2 O of ~11%, while in the case of CuO and Cu 2 O, it was ~8.9% [ 38 ] (for TiO 2 /Cu 2 O, Hussain et al [ 26 ] reported the vaule of ~25%).…”

According to increasing demand for energy, PV cells seem to be one of the best answers for human needs. Considering features such as availability, low production costs, high stability, etc., metal oxide semiconductors (MOS) are a focus of attention for many scientists. Amongst MOS, TiO2 and CuxO seem to be promising materials for obtaining an effective photoconversion effect. In this paper, specific investigation, aimed at the manufacturing of the complete photovoltaic structure based on this concept is described in detail. A set of samples manufactured by DC magnetron sputtering, with various process parameters, is characterized by morphology comparison, layer structure and material composition investigation, and finally by the obtained photovoltaic parameters. Based on SEM studies, it was established that the films are deposited uniformly and complete their formation; without clearly defined faces, the conglomerates of the film grow individually. These are areas with a uniform structure and orientation of atoms. The sizes of conglomerates are in a normal direction range from 20 to 530 nm and increase with film thickness. The film thickness was in the range from 318 to 1654 nm, respectively. The I-V study confirms the photovoltaic behavior of thin film solar cells. The open-circuit voltage (Voc) and short-circuit current density (Jsc) values of the photovoltaic devices ranged from 1.5 to 300 mV and from 0.45 to 7.26 µA/cm3, respectively, which corresponds to the maximum efficiency at the level of 0.01%. Specific analysis of the junction operation on the basis of characteristics flow, Rs, and Rsh values is delivered.

This research focuses on the preparation and characterization of TiO2 thin films in both pure and doped forms. The films were deposited onto glass substrates using the spray pyrolysis technique. The pure film was doped with Cu, Co, and Zn at a constant ratio of 3 wt% in the starting solution. XRD analysis revealed the presence of anatase TiO2 phase in all deposited films. The crystallite size of the pure film was determined using Scherer’s equation and found to be 8.3 nm, while the doped films had sizes of 11.3 nm (Cu), 13.8 nm (Co), and 11.3 nm (Zn). SEM images showed the formation of fine grains with a normal distribution, with average sizes of 27.02 nm (pure), 39.37 nm (Cu), 33.4 nm (Co), and 29.37 nm (Zn) for the respective doped TiO2 films. EDX analysis confirmed the presence of the dopant elements in the deposited films. It was observed that all films exhibited a direct band gap, with a value of 3.79 eV for the pure film, which slightly decreased upon doping. Additionally, various optical constants such as refractive index, extinction coefficient, dielectric constant, relaxation time, and optical mobility were estimated and presented in this study.
