“…The nickel oxide nanostructures have been synthesized by various growth methods such as sol-gel [26], surfactant assisted growth [27,28], thermal decomposition [29,30], and polymer matrix template synthesis [31]. However, most of these methods suffer the disadvantages of obtaining uniform size, well defined morphology and satisfactory product yield.…”

“…The other is to anneal the films whenever each layer is coated. Although this method is complex, it is reported to further improve the film quality, which will be studied later [ 29 ]. Figure 1 shows the fabrication flowchart of NiO x NPs and NiO x films.…”

Solution approaches to NiOx films for electrochromic applications are problematic due to the need of an additional high-temperature annealing treatment step in inert gas. In this study, nanostructured NiOx powder with grain size of about 10.1 nm was synthesized for fabrication of NiOx films for electrochromic application. Non-toxic dispersants of isopropanol and deionized water were used and the whole process was carried out in air. The effects of the number of spin-coating layers, annealing temperature, and the volume ratios of isopropanol to deionized water were systematically investigated. Large transmittance change of 62.3% at 550 nm, high coloration efficiency (42.8 cm2/C), rapid switching time (coloring time is 4 s, bleaching time is 3 s), and good stability were achieved in the optimized NiOx film. The optimized process only required a low processing temperature of 150 °C in air with spin-coating three times and 1:2 volume ratio of isopropanol to deionized water. Finally, good cycle durability of up to 2000 cycles without obvious degradation was demonstrated by cyclic voltammetry tests in a LiClO4/propylene carbonate electrolyte. This study provides a simple and effective approach for fabrication of NiOx films at low temperature in air, which is attractive for further commercialization of electrochromic devices.

“…Using the PLD method, the morphology and density of the deposited materials can be varied by changing the deposition parameters. For example, controlling the oxygen partial pressure and setting it at 200 mTorr, a (111)‐oriented nanostructured NiO film can be deposited, demonstrating lower resistivity and sheet resistance compared with other growth directions, together with positive effects on extracting holes and preventing electron leakage at the interface between the ITO and perovskite. The best‐performing device exhibited a PCE = 17.3% with FF = 81.3%, J SC = 20.2 mA cm −2 , and V OC = 1.06 V, as shown in Figure alongside a schematic image of NiO deposited by the PLD method.…”

In the last decade, hybrid organic–inorganic perovskite‐based solar cells (PSCs) have shown an impressive rate of growth in performance, reaching power conversion efficiencies (PCEs) comparable with the ones exhibited by crystalline silicon devices. Recently, perovskite‐based solar modules (PSMs) have been developed, showing a similar pace in the progress of the reported PCE. Nevertheless, scaling up the dimensions of devices is not a trivial process. To this effect, different deposition and manufacturing techniques have to be implemented. Laser apparatuses have been demonstrated to be fundamental in the production of PSMs, due to the extreme precision needed for manufacturing processes. Herein, an overview of the recent progresses in the application of laser systems in the production of perovskite‐based solar devices is provided. In particular, lasers are used in small‐area PSCs to realize pulsed laser deposition procedures for the realization of perovskite layers and novel electrodes. In the field of PSMs, lasers have boosted the exploitation of substrates, minimizing the dimension of interconnection areas between the cells that form a module and providing the necessary accuracy, repeatability, and level of automation needed for the future industrialization of perovskite‐based solar technology.
