“…Recently, an efficiency of 21.76% was achieved in FPSCs based on the bar‐coating process. [ 204 ] In this work, a crosslinkable multi‐functional ionogel‐modified perovskite polycrystalline film was bar‐coated in situ, enabling high efficiency and stability. The coating process was engineered via bar speed, substrate temperature, and gap distance, showing great potential for large‐area scalability.…”

“…Recently, a multi‐functional ionogel was designed by the incorporation of small‐molecule ionic liquids into a crosslinkable polymer network. [ 204 ] The ionogel‐perovskite films exhibited ultra‐high elongation, toughness, and rapid room‐temperature self‐healing ability, benefiting from the dissipation‐induced toughening and physical cross‐linking sites composed of dynamic hydrogen bonds in the ionogel. Although these gratifying results have shown improved device lifetime and long‐term stability, efforts of universal use and commercialization are still a challenging task, especially the influences on the flexibility and durability of FPSCs.…”

“…Moreover, they reported a multifunctional ionogel perovskite matrix, regulating the mechanical properties by forming polymer networks. [ 204 ] The grain boundary exhibited ultra‐high elongation and toughness, with more than 90% of their initial efficiencies after 25 000 cycles of bending at a radius of 5 mm. When the radius was reduced to 2.5 mm, the ionogel‐perovskite‐based device still maintained an average efficiency of more than 85% after 1000 cycles of bending.…”

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
