“…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

Overview of printing and coating techniques in the production of organic photovoltaic cells

The organic photovoltaic cell (OPV) is composed of multiple layers, and some printing and coating techniques are more suitable than others for a certain type of layer. This paper aims to characterize and compare the most relevant coating and printing techniques that can be used in the manufacture of OPVs. Extensive bibliographic research was carried out on articles published from 1998 to 2020 to identify various aspects OPV, such as the principle of operation, advantages, disadvantages, and which layers can be printed by each technique. The results show that the most used method for the processing of OPVs is spin-coating. In the studies found, rotation was used to coat the active layer, the electron transport layer, and the hole transport layer. The techniques of pad printing, casting, and meniscus are considered useful in the processing of the active layer. Regarding the deposition of the active layer, hole transport layer, electron transport layer, and anode, the rotogravure, crack matrix, spraying, and brushing techniques were satisfactory. Flexography has been used to form the active layer, electron transport layer, and anode. Screen printing, inkjet printing, and knife/blade coating were used in the processing of the active layer, hole transport layer, electron transport layer, anode, and cathode. All the double slot die coating, curtain coating, and slide coating allows simultaneous processing of multiple layers. Techniques compatible with roll-to-roll processing are more likely to be at the center of OPVs in the future, thus making solar photovoltaic technology more competitive.
