“…The cell was completed by infiltrating the perovskite through the carbon electrode filling the whole triple layer mesoporous stack delivering an efficiency of 12.8% and remarkable stability over 1000 h of full sunlight. 48 The specified thicknesses (≥1 µm) are those typically seen in screen printed layers even though thicknesses down to a few hundred nms can be achieved (the very thin compact layer, ≤100 nm, is typically still deposited via other techniques such as spray pyrolysis 48 or ALD 45 ) as demonstrated in the quadruple stacks by Cao et al 49 There, an additional 800 nm mesoporous nickel oxide interlayer was screen printed just underneath the 10 µm carbon black/graphite to improve charge collection and reduce charge recombination resulting in a PCE of 15%. A similar architecture (and PCE) had been fabricated by Xu et al via blade coating the layers.…”

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.

“…[43] Influence of the sheet resistance increase can be largely overcome by optimizing the device structure for single cells, for example, depositing 100 nm thick Au busbar under the electron transport layer [44] or designing suitable device geometry, for example, tuning the width of the subcells and optimizing the interconnection between subcells for modules. [45] Fabrication techniques such as hybrid chemical vapor deposition (CVD), [46][47][48][49] spray coating, [50,51] screen printing, [52,53] and hot casting [54,55] have been developed and shown promising results in achieving large-area uniformity and easy accessibility. However, most large-area single cell/module optimization is based on MAPbI 3 and FAPbI 3 , which are known to suffer from the instability issue.…”

Mixed cation hybrid perovskites such as Cs [16][17][18] and adjusting the composition of perovskite films, [19][20][21][22] research efforts are also urgently needed to increase the scalability of research findings obtained in research labs and make this technology amenable for industry. There are two main challenges we are still facing.(I) The first is the stability challenge. At present stability of PSCs is still poorer than inorganic semiconductor based solar cells, foe example, crystalline silicon solar cells and thin film copper indium gallium selenide (CIGS) solar cells. [10,[23][24][25] To overcome the instability issue, external protections (e.g., perovskite surface functionalization, [26] utilization of chemically inert electron transport materials, hole transport materials and top electrode, deposition of additional protection layer, etc.) have been attempted. [27][28][29] Stability of the perovskite layer itself is Large-Area Perovskite Solar Modules

This work investigates non-rare-earth phosphor (Sr4Al14O25:Mn4+, 0.5%Mg) with intensively red luminescence as a luminescent down-shifting layer for perovskite solar cells. The power conversion efficiency of the fabricated device with a structure of NiO/CH3NH3PbI3/[6,6]-phenyl C61-butyric acid methyl ester/Au coated with phosphor layer shows a 10% increase as compared with that of the control devices. Importantly, the phosphor layer coating can realize UV-protection as well as waterproof capability, achieving a reduced moisture-degradation of CH3NH3PbI3 perovskite upon applying an UV irradiation. Therefore, perovskite devices using this luminescent coating show a combined enhancement in both UV down-shifting conversion and long term stability. This can be expanded as a promising encapsulation technique in the perovskite solar cell community.
