the representative of the third-generation photovoltaics, have attracted great attention owing to unique properties such as light weight, flexibility, low cost, and low-temperature solution process. PCE of OSCs has been greatly improved via continuous development of novel semiconducting materials and performance optimization in the past two decades. [3][4][5] Lead halide perovskites, as star semiconducting materials, have obtained enormous attention in optoelectronic fields due to their outstanding properties, such as, tunable band gaps, high absorption coefficient, high charge carrier mobility, and long carrier diffusion lengths. [6][7][8][9][10][11] Until 2021, PCEs of perovskite/silicon tandem cells and OSCs have exceeded 29% and 18%, respectively. [12][13][14] However, the high-efficiency cells are usually prepared by spin-coating, with an active area of less than 0.1 cm 2 . There is no doubt that the development of OSCs and PSCs will go to large-scale industrial production, thus the challenge is achieving large-area uniform active layers. However, due to the uneven centrifugal force in the traditional spin-coating process, the thicknesses at the center and the edge of the substrate is different, especially for large-area films. The thick area shows increased nonradiative recombination loss. The thin area shows reduced lightharvesting ability and increased pinholes, leading to reduced efficiency. To address these issues, developing large-area coating methods is an effective way. [15] So far, various methods have been applied to large-area film fabrication, including spray coating, [16][17][18][19] dip coating, [20,21] slot-die coating, [22,23] and bladecoating. Among these techniques, blade-coating has achieved the greatest success, with the best PCE of ≈22%.In this review, we summarize the recent advances of bladecoating techniques for fabricating large-area PSCs and OSCs, and analyze the issues that need to be solved in blade-coating technology. We hope it can provide new strategies for the commercialization of the third-generation solar cells. Blade-Coating TechnologyBlade-coating is a widely recognized method for the preparation of large-area films. Blade-coating method, with the merits of efficient material utilization, in situ crystallization and adjustable parameters, has been investigated in depth for the preparation of various thin films. [15] Figure 1 demonstrates the High-efficiency perovskite solar cells (PSCs) and organic solar cells (OSCs) are promising alternatives for silicon-based solar cells. At present, the key point for commercialization of PSCs and OSCs is realizing large-scale production while maintaining the same high efficiency as small-area ones. In this review, the blade-coating method for preparing large-area films is introduced first and the recent advances of blade-coated OSCs and PSCs are summarized. Then, the effects of blading parameters on the crystal growth and film formation of the light-harvesting materials are discussed. Moreover, the limitations and advantages of making h...

“…Pan et al prepared a patterned substrate with periodic polystyrene (PS) nanochannels utilizing a blade coating method and then introduced perovskite ink using a similar process (Figure 1b). [35] During the movement of the meniscus, capillary force draws perovskite ink into the prepared PS channels (Figure 1c). After the crystallization of perovskite, the PS channel was washed with toluene, leaving separated perovskite NWs.…”

“…Flexible transparent electrodes (FTEs) have been widely used in various wearable and foldable electronic devices including organic photovoltaic devices and lightemitting diodes and displays. [1][2][3][4][5][6][7][8] Diverse conductive nanomaterials, such as graphene, carbon nanotubes, silver nanowires (AgNWs), and metal nanoparticles, have been used for making FTEs. [9][10][11][12][13][14] Among them, AgNWs serve as the most frequently used material due to high transmittance, low sheet resistance, and good flexibility.…”
