“…Nickel oxide thin films can be synthesized using various techniques. Among them, the spin coating technique is a more convenient and easy way by which homogenous and high-quality films can be obtained at a low cost [ 90 ]. This technique is used to deposit a thin layer of materials on a flat surface by spinning the substrate at high speeds ranging from 1000 to 8000 rpm.…”

In just a few years, the efficiency of perovskite-based solar cells (PSCs) has risen to 25.8%, making them competitive with current commercial technology. Due to the inherent advantage of perovskite thin films that can be fabricated using simple solution techniques at low temperatures, PSCs are regarded as one of the most important low-cost and mass-production prospects. The lack of stability, on the other hand, is one of the major barriers to PSC commercialization. The goal of this review is to highlight the most important aspects of recent improvements in PSCs, such as structural modification and fabrication procedures, which have resulted in increased device stability. The role of different types of hole transport layers (HTL) and the evolution of inorganic HTL including their fabrication techniques have been reviewed in detail in this review. We eloquently emphasized the variables that are critical for the successful commercialization of perovskite devices in the final section. To enhance perovskite solar cell commercialization, we also aimed to obtain insight into the operational stability of PSCs, as well as practical information on how to increase their stability through rational materials and device fabrication.

“… 12,13 NiO thin films have been deposited by a variety of physical routes (such as magnetron sputtering, 14–16 pulsed laser deposition, 17 and electron beam deposition 18 ) and chemical routes (including sol–gel processing, 19 spray pyrolysis, 20 and atomic layer deposition 21 ). NiO shows promise in myriad applications, such as thin film transistors, 22–25 pn junctions, 26–29 electrochromic displays, 30 resistive switching memory, 31 optoelectronic, 32,33 and photovoltaic 17,33–35 devices. NiO based printed devices have been used in several applications, such as pesticide detection, 36 as thermistors, 37 and as hole-transport layers in solar cells.…”

“…Ammonia was added drop by drop to maintain the pH value at 10.4. The cleaned micro glass and ZnO seed layer [16] was used as substrates and they were immersed vertically with the help of a substrate holder. The solution was stirred by magnetic stirrer at 70±5 °C in order to get the uniform coating on the substrate.…”

In this study, we report the synthesis of Zn0.075Cu0.025O films by chemical bath deposition to determine the effect of substrate (glass slide or ZnO seed layer) on the structural and H2 gas sensing properties of the produced films. The crystal phase, structural topography, surface morphology and functional groups of the as-synthesized films as well as H2 gas sensing properties were investigated. Although both films have a hexagonal wurtzite structure, ZnO seed layer-based Zn0.075Cu0.025O film is more crystalline than glass slide-based Zn0.075Cu0.025O films. ZnO seed layer-based Zn0.075Cu0.025O films exhibited much more nanorod and less nanosphere forms compared to glass slide-based Zn0.075Cu0.025O films. EDX analysis and Raman spectra of both samples confirmed the presence of defects in Cu:ZnO samples. ZnO seed layer-based sensors showed higher response (140%) and lower operating temperature (80°C) compared to glass slide-based sensors (87% response and 140°C operating temperature). The most important thing to note here is that the fabricated sensors exhibited high response at room temperature. The responses at room temperature was found as 46% and 23% for the ZnO seed layer-based and glass slide-based sensors, respectively. Sensors operating at room temperature are especially important for commercial applications.
