“…There is an inverse relationship between doping concentration and transmittance, thus as the doping concentration increases, the transmittance will drop significantly. [50,51]. It can be found that by increasing the Ar gas concentration, E g changes, but it shifts towards the red region, as exhibited in figure 8(a) for all pure ZnO films.…”

Due to their unique scintillation, phosphorescence, magnetic, and catalytic properties, rare earth oxide compounds have recently become one of the most in-demand materials used in different ways. The current study investigated the impact of Ar:O2 gas flow variation on the deposition of La2O3-doped zinc oxide thin films (TFs) on silicon dioxide (SiO2) substrates using the radio frequency sputtering technique. FE-SEM analysis has shown a smooth surface topology and purity of La2O3-doped ZnO TFs. X-ray diffraction analysis exhibited a single-phase hexagonal wurtzite-type structure in TFs. A UV–Vis–IR spectrophotometer examined the optical characteristics of ZnO and La2O3-doped ZnO TFs in 300–800 nm wavelength range. The bandgap of La2O3 doped ZnO TFs changed from 2.9 to 3.1 eV as argon and oxygen concentrations in (Ar:O2) gas flow changed. A variation in optical constants such as dielectric constants, refractive index, and extinction coefficient was observed when ZnO and La2O3-doped ZnO TFs were exposed to variable (Ar:O2) gas flow ratios. The photoluminescence analysis of ZnO and La2O3-doped ZnO TFs was performed at an excitation wavelength of 330 nm. Atomic force microscopy further revealed that La2O3 doping resulted in smoother surfaces and smaller grain sizes. This comprehensive study provides valuable insights into the relationship between doping, gas composition, and the optical and structural properties of ZnO TFs. The obtained results on the optimal flow rate of argon gas provide valuable insights for determining the appropriate deposition conditions of La2O3-doped ZnO TFs, specifically for their application in solar thermal systems.

“…The concentration and kind of dopants that are introduced to a semiconducting material are the primary factors that affect the electrical characteristics of the material as a whole [8]. Doping a material with an impurity results in the creation of additional electrons in N-type materials, while doping a material with an impurity results in the creation of additional holes in P-type materials [21,22]. When it comes to the optical qualities, the absorption spectra of N-type and P-type oxides and sulphides are comparable in the visible and near-infrared areas of the electromagnetic spectrum.…”

This review paper focuses on the current advancements in improving the optical and electrical properties of n-type and p-type oxides and sulphide semiconductors. The demand for high-performance semiconductors has grown significantly in recent years due to their wide range of applications in electronic and optoelectronic devices. However, the inherent limitations of these materials such as low conductivity, poor optical absorption, and low carrier mobility have hindered their widespread adoption. This paper provides an overview of various techniques that have been employed to improve the optical and electrical properties of n-type and p-type oxides and sulphide semiconductors. These techniques include doping with impurities, defect engineering, surface passivation, and bandgap engineering. The paper also discusses the recent progress in the synthesis of these materials using different methods such as chemical vapour deposition, sol-gel, and hydrothermal methods. Furthermore, this review paper highlights the applications of these improved materials in various fields such as solar cells, light-emitting diodes, photocatalysis, and sensing. Finally, the paper concludes with the prospects of these materials and the challenges that need to be addressed to achieve their full potential. Overall, this review paper provides valuable insights into the current state-of-the-art techniques for improving the optical and electrical properties of n-type and p-type oxides and sulphide semiconductors, which can potentially lead to the development of high-performance devices.

Perovskite solar cells (PSC) have drawn interest in recent years due to their progressively improving power conversion efficiency (PCE), lightweight and wearable properties, straightforward solution fabrication process, suitability for flight, potential for deployment in ultra-lightweight space applications, and low-cost material constituents, among other factors. The efficiency of perovskite solar cells has exceeded 25% by developing novel low-cost synthesis methods and advancements in interface and electrode materials, enhancing the production of high-quality perovskite films. Moreover, perovskite solar cells' stability has been the focus of several studies. This review primarily examines recent advances in perovskite solar cells concerning their properties, composition, and synthesis methods. The main focus is to study transition metal oxide (TMO)-based nanocomposites for various PSC layers, including electron transport layers (ETLs), hole transport layers (HTLs), and other layers. These TMO-based nanocomposites were employed in perovskite solar cells, considering their band gap, carrier mobility, transmittance, and other relevant factors. The prospects of different TMO (iron, titanium, copper, nickel, etc.) -based perovskite solar cells and their potential for commercialization feasibility have also been examined.
