“…Roll-to-roll printing is a mature and manufacture-oriented strategy to product flexible electronic devices on a large scale. − Cooperating with the precast gravure, desired patterned component layers can be produced with high throughput. In recent years, microgravure was commonly used in thin-film solar cells, which was suitable for depositing film at a thickness of several micrometers.…”

Perovskite solar cells (PSCs) are being rapidly developed at a fiery stage due to their marvelous and fast-growing power conversion efficiency (PCE). Advantages such as high PCE, solution processability, tunable band gaps, and flexibility make PSCs one of the research hot spots in the energy field. Flexible PSCs (f-PSCs) owing to high power-to-weight ratios can be promising candidates to serve as power sources in mobile energy systems, space energy systems, portable functional devices, and so on. Herein, we give a review on recent progress in f-PSCs involving flexible substrates and flexible transparent electrodes, performance enhancement by optimizing functional layers, large-scale fabrication techniques, flexibility promotion strategies, and their potential applications. Furthermore, perspectives are discussed on the future development of f-PSCs.

“…Unlike the processes discussed earlier, roll-to-roll printing is limited to flexible substrates only, which have already been demonstrated in the manufacturing of several kinds of electronic devices. [223,[236][237][238][239][240][241][242] The equipment is illustrated in Figure 11a,b. With the NH 4 Cl additive, which will assist the crystallization in air, a PCE of 11.16% was achieved.…”

Solar photovoltaic (PV) energy is taking an increasingly important role all over the world. Among different solar cells, perovskite solar cells (PSCs) are regarded as the next-generation technology that could further decrease the manufacturing cost with comparable efficiency to silicon solar cells. Perovskite materials possess marvelous optoelectronic properties like high light absorption coefficient, tunable bandgap, and long charge diffusion length. [1][2][3][4][5][6][7][8] Recently, state-of-the-art devices have achieved tremendous progress with power conversion efficiencies (PCEs) exceeding 25%. [9][10][11] Besides, with the intrinsic mechanical flexibility and low-temperature processability, PSCs are able to be prepared on flexible substrates, which will broaden the application areas in portable electronics, wearable devices, and so on. [12][13][14][15][16][17] Moreover, PSCs could be fabricated by the roll-to-roll printing process, which has already been successfully demonstrated in the commercialization of organic PVs. Needless to say, flexible perovskite solar cells (FPSCs) have become a significant topic in practical applications of PSCs (See Figure 1). [18] Kumar et al. reported the first FPSC in 2013, and the PCE was only 2.62%. [19] In this work, polyethylene terephthalate (PET) was used as a flexible substrate, followed by low-temperature deposited ZnO nanorods. Currently, the record PCE of flexible devices is still lower than that of rigid ones. To some extent, the loss is inevitably caused by the trade-off between the requirement of mechanical flexibility for application and mechanical rigidity for fabrication. Different from rigid PSCs, the morphologies of the layers in FPSCs are difficult to control

“…Furthermore, it can have a certain effect on the active layer of organic optoelectronic devices. It is crucial to maintain a very low initial deposition rate and achieve precise control throughout the device fabrication process. , The high-temperature metal particles can permeate into the organic film, and excessive metal penetration can lead to an increase in leakage current , and poor device stability. − In recent years, with the rapid development of the organic optoelectronic industry, there has been an increasing focus on large-scale and low-cost printing fabrication techniques for flexible optoelectronic devices. − Printing electronic technologies, such as screen printing, inkjet printing, , transfer-printing, , etc., have emerged as viable options for industrial-scale production and cost-effectiveness. Among these techniques, transfer-printing is a novel method that offers simplicity, nondestructiveness, and compatibility with solution printing technology .…”

Organic photodetectors (OPDs) have garnered significant attention due to their low cost, flexibility, and simple manufacturing process. In this work, we conducted a systematic study of different transfer-printing parameters with the aid of residual solvents. We found that the amount of residual solvent and heating time during transfer-printing were critical for successful fabrication. The results showed that compared to OPDs fabricated by vacuum evaporation, transfer-printed OPDs exhibited a reduction in dark current by approximately 1 order of magnitude while maintaining a comparable photocurrent. Transfer-printed OPDs also showed higher responsivity, specific detectivity, and a wider linear dynamic range. The impact of transfer-printing on the interface is investigated using electron-only devices, revealing that the transfer-printing process improved the interface between the Ag electrode and electron transport layer and resulted in a higher charge carrier drift mobility and lower total trap density. A flexible OPD using the transfer-printing process is also demonstrated. This work presents a novel technique that is expected to play a role in the transfer-printing of OPDs.
