“…In addition, AZO has a smaller particle size and a smoother surface than ZnO, which can increase light transmittance (Figs. 2 , and S2 ) 40 , 41 . Thus, the perovskite material in the AZO/Glass/FTO/meso-TiO 2 /Perovskite configuration can absorb more visible light than the ZnO/Glass/FTO/meso-TiO 2 /Perovskite and Glass/FTO/meso-TiO 2 /Perovskite.…”

“…The levels of frictional resistance are impacted by the coefficient of friction (COF). In other words, A lower friction coefficient increases wear resistance 37 , 40 . Figure 6 shows the COF data of AZO and ZnO coatings at the scratch load of 2968 μN.…”

“…Mechanical resistance containing elastic modules, wear resistance, coating hardness 34 – 38 , and optical properties, including UV protection and high transmittance of light in the visible range, can be achievable by adding dopants to produce cover glasses 34 , 36 , 39 Regarding the optical properties, Al doping to ZnO can reduce the structural defects and modify the crystal structure of ZnO, which leads to a decrease in the refractive index of the material. As a result, the AZO layer has a lower refractive index than pure ZnO, which means that it can let more light pass through the material 40 – 42 . On the other hand, one of the goals of this work was to prepare coatings with high wear resistance, which was provided by aluminum doping in the ZnO network.…”

Organometal halide perovskite solar cells have reached a high power conversion efficiency of up to 25.8% but suffered from poor long-term stability against environmental factors such as ultraviolet irradiation and humidity of the environment. Herein, two different multifunctional transparent coatings containing AZO and ZnO porous UV light absorbers were employed on the front of the PSCs. This strategy is designed to improve the long-term stability of PSCs against UV irradiation. Moreover, the provided coatings exhibit two additional roles, including self-cleaning and high wear resistance. In this regard, AZO coating showed higher wear resistance compared to the ZnO coating. The photocatalytic self-cleaning properties of these prepared coatings make them stable against environmental pollutants. Furthermore, appropriate mechanical properties such as high hardness and low coefficient of friction that leads to high resistance against wear are other features of these coatings. The devices with AZO/Glass/FTO/meso-TiO2/Perovskite/spiro/Au and ZnO/Glass/FTO/meso-TiO2/Perovskite/spiro/Au configurations maintained 40% and 30% of their initial performance for 100 h during 11 days (9 h per day) against the UV light with the high intensity of 50 mW cm-2 which is due to higher absorption of AZO compared with ZnO in the ultraviolet region. Since AZO has a higher light transmission in the visible region in comparison to ZnO, perovskite cells with AZO protective layers have higher efficiency than perovskite cells with ZnO layers. It is worth noting that the mentioned features make these coatings usable for cover glass in all types of solar cells.

Al: ZnO films are prepared by spraying from the pure ZnO and Al with doping at different weight ratios 0.01, 0.03, 0.05, and 0.09. X-ray diffraction, atomic force microscopy, and energy-dispersive X-ray spectroscopy are used to analyze the structural properties of the films. The results of X-ray diffraction prove that polycrystalline Al:ZnO with a hexagonal wurtzite structure is preferentially oriented on the c-axis, and this is further confirmed by transmission electron microscopy. In addition, 0.09 wt% of Al-doping shows high orientation and homogeneity with the (002) plane, which leads to an increase in the surface roughness properties of the thin films as the root main square by 57.4%. The annealing process at high temperatures increases the conductivity of the Al:ZnO films. The rate of electronic mobility increases slightly with low doping and decreases with increasing doping until it reaches its lowest value (0.1 cm2 (V.s)−1) at a doping ratio of 0.035 wt%. The samples show considerable response for CO at 80 ppm gas concentration with gas responses of 85% and 40% at 90 °C for 0.03 wt% Al:ZnO and ZnO films, respectively. The overall study observed that fabricated sensor Al3+-doped ZnO is reliable and very rapid in detecting carbon monoxide vapors at moderately high temperatures and low gas concentrations.

“…In addition, the excellent optoelectronic properties of AZO films make them widely used in other fields, such as liquid crystal displays [ 80 , 81 , 82 ], anti-static films [ 83 ], thermal mirrors [ 84 ], transparent surface heaters [ 85 , 86 ], and infrared stealth materials [ 87 , 88 , 89 ], radar shielding protection [ 90 ], glucose sensing [ 91 ], biosensors [ 92 ], antibacterial applications [ 93 ], etc. The AZO thin-film material is non-toxic, has a simple preparation process, doping that is easy to achieve, and cheap raw materials that are easy to obtain; therefore, it has great development potential.…”

Due to the excellent performance and low cost of the new aluminum-doped zinc oxide (AZO) film, it is expected to replace the mature indium-doped tin oxide (ITO) film. The research status and progress of AZO transparent conductive films are summarized in this review. Moreover, the structure, optoelectronic properties, and conductive mechanism of AZO thin films are also detailed. The thin films’ main preparation processes and the advantages and disadvantages of each process method are mainly discussed, and their application fields are expounded. AZO thin films with multicomponent composite structures are one of the promising development directions in transparent conductive oxide (TCO) thin films. The development of various preparation processes has promoted the production and application of thin films on a broad scale. Finally, some improvement schemes have been proposed to improve the comprehensive performance of the film. The industrialization prospects of the AZO film, as well as its great development potential in the digital world, are discussed.
