Flexible and light-weight solar cells are important because they not only supply power to wearable and portable devices, but also reduce the transportation and installation cost of solar panels. High-efficiency organometal halide perovskite solar cells can be fabricated by a low-temperature solution process, and hence are promising for flexible-solar-cell applications. Here, the development of perovskite solar cells is briefly discussed, followed by the merits of organometal halide perovskites as promising candidates as high-efficiency, flexible, and light-weight photovoltaic materials. Afterward, recent developments of flexible solar cells based on perovskites are reviewed.

Research Update: Large-area deposition, coating, printing, and processing techniques for the upscaling of perovskite solar cell technology

To bring perovskite solar cells to the industrial world, performance must be maintained at the photovoltaic module scale. Here we present large-area manufacturing and processing options applicable to large-area cells and modules. Printing and coating techniques, such as blade coating, slot-die coating, spray coating, screen printing, inkjet printing, and gravure printing (as alternatives to spin coating), as well as vacuum or vapor based deposition and laser patterning techniques are being developed for an effective scale-up of the technology. The latter also enables the manufacture of solar modules on flexible substrates, an option beneficial for many applications and for roll-to-roll production.

“…57 Similarly to other thin-film or OPV solar cells, PSCs can be bent down to millimetre scale radius, and are characterized by low weight. 88 As mentioned in the introduction, these features make it an ideal choice for the energy harvesting of portable devices or for any application in which the energy source should be conformed to a curved surface like in building-integrated photovoltaics.…”

“…88 Indeed a bending test on PET-ITO can only be conclusive until ITO does not crack, since the ITO layer is brittle and starts to fail before the perovskite itself, and the cracks propagate in the active layer leading to the device failure. 94 On the other hand, when a flexible bottom electrode is used instead of ITO, the PSC can be bent much more.…”

“…94 On the other hand, when a flexible bottom electrode is used instead of ITO, the PSC can be bent much more. 88 Since the main material used to substitute ITO is usually highly conductive PEDOT:PSS (even together with a conductive grid in the case of the most efficient TCO-free PSC), all the TCO-free PSCs published to date present a p-i-n structure. The only alternative to PEDOT:PSS tested to date are carbon nanotubes, but the PCE is limited to 5.4%.…”

a Perovskite solar cells have attracted enormous interest since their discovery only a few years ago because they are able to combine the benefits of high efficiency and remarkable ease of processing over large areas. Whereas most of research has been carried out on glass, perovskite deposition and synthesis is carried out at low temperatures (o150 1C) to convert precursors into its final semiconducting form. Thus, developing the technology on flexible substrates can be considered a suitable and exciting arena both from the manufacturing view point (e.g. web processing, low embodied energy manufacturing) and that of the applications (e.g. flexible, lightweight, portable, easy to integrate over both small, large and curved surfaces). Research has been accelerating on flexible PSCs and has achieved notable milestones including PCEs of 15.6% on laboratory cells, the first modules being manufactured, ultralight cells with record power per gram ratios, and even cells made on fibres.Reviewing the literature, it becomes apparent that more work can be carried out in closing the efficiency gap with glass based counterparts especially at the large-area module level and, in particular, investigating and improving the lifetime of these devices which are built on inherently permeable plastic films. Here we review and provide a perspective on the issues pertaining progress in materials, processes, devices, industrialization and costs of flexible perovskite solar cells. Broader contextFor a number of years, solar cells had been considered as an inferior energy technology due to high cost -even in the renewable energy paradigm; however, more recently progress in materials processing and engineering of highly efficient and stable solar panels have helped them emerge as a frontline renewable energy technology with energy payback time that has been lowered from over a decade to a couple of years (at least in some parts of the world) during the last ten years. Commercial solar panels are typically manufactured on rigid platforms. Fabricating them on flexible substrates, such as transparent plastics and metallic foils, would enable effective harvesting of energy in a number of diverse areas from indoor electronics to automobiles and from building integrated photovoltaics to portable applications. Furthermore, it would open up web-based roll-to-roll fabrication conducive to massive throughputs. Solution processable perovskite solar cells offer promising opportunities towards this end. Being these cells the most efficient among the solution processable ones, with efficiency in their laboratory scale devices on par with the commercially available silicon and thin film counterparts, significant recent efforts devoted to their manufacturing on flexible substrates have seen efficiencies rise as high as 15.6% together with moderate stability. We approach the developments in this area by critically analyzing the factors affecting the final performance indicators such as efficiency, stability, and functionality and relate these to its proces...
