“…Organometal halide perovskites (OHPs) have good solubility due to their ionic nature, which enables low-temperature solution processes for perovskite solar cells (PSCs) manufacturing, including screen printing, blade coating, slot-die coating [1][2][3][4] . These manufacturing methods are well compatible with roll-to-roll (R2R) large-scale manufacturing processes to fabricate lightweight flexible PSCs, which can significantly reduce the manufacturing cost and show strong potential for application in wearable electronics, portable charger, flying objects, etc.…”

“…After the optimization of the elastic interface by adding t‐BP and Li‐TFSI, Figure b shows an improved PCE (13.49%), with an open‐circuit voltage ( V OC ) of 1.1 V, a short‐circuit current ( J SC ) of 21.53 mA cm −2 , and a FF of 0.57. The mechanism using t‐BP and Li‐TFSI as additive has been well addressed in our previous papers . The addition of 4‐tert‐butylpyridine (TBP) and Li salt can effectively retard interfacial charge recombination, which is conductive to enhance V OC and FF, as can be confirmed by the parameters in Table .…”

Wang et al reported flexibly assembled and readily detachable photovoltaics that were also made by two electrodes . It is widely accepted that the crucial step determining the device performance is the formation of intimate interfacial electrical structure between the laminated parts which is the main region where the internal dynamic process of the cells occurs.…”

“…In this paper, we have systematically studied the interfacial elastic contact, which is critical to the interfacial charge transfer and the final photovoltaic performance of the device. We reported a novel stacking planar cell architecture consisting of two parts ( Figure ) . One part is FTO/electron transport layer (ETL)/perovskite/spiro‐OMeTAD/p‐type organic semiconductors (p‐OS) while the other part is FTO/p‐OS.…”

architecture that can be fabricated based on this cell. Examples of such devices are planar heterojunctions and mesoscopic structures, which have already exhibited very impressive performance. However, the cost, stability, and large-scale production requirements to realize commercialization of these cells should be considered. [5][6][7] Hence, many new kinds of structures based on developed alternative materials and protocols have been designed to solve the problems of the traditional cell architectures (usually involving noble metal electrodes prepared by high-vacuum deposition techniques), such as carbon-based cells and sandwich solar cells. [8][9][10][11] The majorities of organic photovoltaic devices or organic-inorganic devices are generally prepared by sequential deposition; that is, another layer is prepared after one functional layer is prepared. This method can ensure the maximum interfacial ohmic contact between two layers. However, at the same time, placing one layer after another layer indicates that whether the preparation conditions will damage the previous functional layer should be considered. Hence, consecutive deposition cannot achieve sufficient performance and structural regulation of a functional layer. If a functional layer is destroyed, especially the sensitive perovskite light-absorbing layer, the entire device will lose efficacy and become unusable. Sandwich-type thin-film solar cells with top and bottom electrodes, such as dye-sensitized and laminated PSCs, are of great interest, because the cathode and anode electrodes of these devices are manufactured individually rather than layer upon layer. It is easier to repair and maintain an electrode (cathode or anode) than the whole device. Moreover, this structure eliminates the vacuum evaporation of noble metal. Given the low-cost fabrication and unique structural advantages of sandwich-type thin-film solar cells, relative large-scale fabrication technique is believed to be reliable and imperative while all the fabrication of PSCs has been achieved by doctor-blade and slot-die coating outside the glovebox under ambient air conditions. [12,13] Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) is a cheap conducting polymer with high conductivity (up to several thousands of Siemens per centimeter), and can be easily prepared into films by spin-coating, spraying, or printing. PEDOT:PSS has been widely used as an electrode or a charge collection layer in organic photovoltaics, p-i-n perovskite solar cells, and light emitting diodes because of its electrical conductivity, transparency, and solution Stacking perovskite solar cells (PSCs) are emerging cells with two detached electrodes during fabrication process, in which the crucial step is the intimate mechanical and electronic contact between the laminated parts. The interfacial elastic contact of stacking PSCs with four different p-type organic semiconductors has been systematically studied. Studies confirm that poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS...

“…Moreover, Shi and co‐workers designed a flexibly assembled and readily detachable PSC with PEDOT:PSS electrode (Figure 16c). [ 154 ] By introducing tert ‐butylpyridine and Li salt in PEDOT:PSS layer, an improved interfacial contact was achieved to facilitate the hole transport and suppress charge combination, thus resulting in a PCE value of 14.62%. Meanwhile, the device could withstand repeated assembly and disassembly tests for more than 100 cycles without any loss in PCE.…”

Perovskite solar cells (PSCs) represent a promising next‐generation photovoltaic technology considering their high efficiency and low cost. At the current stage, resolving the stability bottleneck is extremely urgent to realize PSCs’ commercialization since the efficiencies of these cells are improved to a level comparable to that of crystalline silicon solar cells. Similar to other functional layers, a proper choice of the rear electrode atop the perovskite layer is equally important for achieving the device's long‐term stability. This topic has not been comprehensively reviewed before. Here, recent progress in the development of rear electrodes based on metals, carbon‐based materials, transparent conductive oxides, and conductive polymers is summarized, especially focusing on their different impacts on the device's long‐term stability and associated degradation mechanisms. In the context of practical applications, the impacts of rear electrode materials on the device's overall efficiency and cost‐effectiveness are also discussed.
