“…The projected two-terminal efficiency for stabilized cells exhibits a record value of 18.5% (see Table 1 and Fig. S9), which is the highest reported value for a solution-processed two-terminal tandem device, exceeding HP/HP tandem devices of 17.0%, 35 HP/polymer tandem devices of up to 16%, 58 and HP/chalcogenide tandems up to 15.9%. 38 The excellent current matching of our solution processed low-bandgap CIS cell with our highly efficient, NIR-transparent MAPbI3 perovskite cells is accountable for this high two-terminal performance that exceeds even some recent reports of two-terminal devices with 1.1 eV bandgap silicon or 1.2 eV bandgap perovskite bottom cells.…”

“…[171] Ouyang et al fabricated PVSCs using double interfacial layers containing zwitterionic rhodamine 101 and LiF between the active layer (PCBM) and electrode (Ag). [174] Remarkably, a high PCE of 16% was realized for these perovskite/PSCs, exhibiting an excellent synergic effect. Single interlayer device with rhodamine exhibited 11%.…”

“…[171][172][173][174] In 2014, Zhang et al constructed a high-performance organic/inorganic PVSC device with the architecture of ITO/ PEDOT:PSS/perovskite(CH 3 NH 3 PbI 3 )/PCBM/interlayer/ Ag by employing polyelectrolyte zwitterion interlayer poly[3-(6-trimethylammoniumhexyl)thiophene] (P3TMAHT). However, these interlayer materials are costly and make the fabrication process complicated.…”

“…J SC was increased from 16.00 mA cm −2 (control device) to 17.10 mA cm −2 for P3TMAHT-based device, while V OC was improved from 0.849 (control device) to 0.899 V for P3TMAHT device. [174] A 90 nm thick perovskite layer as a front subcell (PC 61 BM/ perovskite planar hetero junction) and a 100 nm thick layer of polymer as back subcell (PCE-10:PC 71 BM blend) were used in a recombined layer (30 nm C 60 -SB, 10 nm Ag, and 10 nm MoO 3 ) to fabricate an efficient tandem perovskite/PSCs with the structure of ITO/PEDOT:PSS/CH 3 NH 3 PbI 3 /PC 61 BM/C 60 -SB/ Ag/MoO 3 /polymer BHJ/tertiary amino-fulleropyrrolidine (C 60 -N)/Ag. [172] The PCE of the devices constructed with the configuration of glass/ITO/PEDOT:PSS/CH 3 NH 3 PbI 3−x Cl x /PCBM/LiF/Ag was increased to a large extent from 11.1% (single interlayer) to 13.2% by inserting double interlayers in the device.…”

“…Single interlayer device with rhodamine exhibited 11%. [174] Sulfamic acid (NH 3 SO 3 , SA) (Scheme 4) is well-known zwitterionic acid for its ability to convert PbI 2 into perovskite precursors in DMF and perovskite into perovskite crystals as well as growth of perovskite crystals on the substrate. [172] In the preparation of perovskite (CH 3 NH 3 PbI 3−x Cl x ) solution, a little more amount (1.4 m) of Pb 2+ ions were added and a solution with a little high concentration (instead of 0.8 m) was used to obtain uniform films by controlling the growth rate of perovskite crystals.…”

are covalently bonded and their unique characteristics enable them to demonstrate special performance in applications and distinguish them from other conventional organic salts. [12][13][14] Recently, a significant attention has been paid to the use of zwitterions owing to their solubility in polar solvents for solution processing, [15][16][17] and dipole formation for the transfer of carriers [18][19][20] and ions. [21][22][23] Zwitterions have emerged as alternatives to the widely used building blocks such as conventional ionic groups, for developing new functional materials. The presence of both negative and positive ions in the same molecule enables zwitterions to develop interfacial dipole. The ability of zwitterions to develop interfacial dipole provides a new pathway to utilize them as interfacial layer in optoelectronic devices, including organic solar cells (OSCs), perovskite solar cells (PVSCs), and organic light-emitting devices (OLEDs), as well as electrolyte additives for energy devices such as lithium ion batteries (LIBs).It is well known that the ability to transport the charge carriers between the electrodes and organic layers is very crucial to obtain highly efficient electronic devices. [24] A mismatch between the energy levels of organic layers and inorganic electrodes leads to the generation of an energy barrier that hampers the extraction or injection of charge carriers. [25] To get rid of this obstacle, an interlayer between the electrodes and organic layers is applied to facilitate the transfer of charges in organic devices. In OLEDs, interlayers are used to enhance charge injection and reduce the height of Schottky barrier. While in the case of OSCs and PVSCs, apart from the enhancement in charge injection, they also play an important role to increase the built-in electric field across the active layer, ensuring efficient extraction of photogenerated charge carriers. [26][27][28][29][30] Therefore, the design and development of effective interlayer materials for interfacial modification are crucial for high-performance electronic devices. Recently, some significant advances have been demonstrated by applying an interfacial layer between the electrodes and organic layers, resulting in power conversion efficiencies (PCEs) to exceed 14% for single-junction OSCs by choosing appropriate photoactive layer. [31,32] Among different interlayer materials used so far, zwitterionic materials have been proved Zwitterions, a class of materials that contain covalently bonded cations and anions, have been extensively studied in the past decades owing to their special features, such as excellent solubility in polar solvents, for solution processing and dipole formation for the transfer of carriers and ions. Recently, zwitterions have been developed as electrode modifiers for organic solar cells (OSCs), perovskite solar cells (PVSCs), and organic light-emitting devices (OLEDs), as well as electrolyte additives for lithium ion batteries (LIBs).With the rapid advances of zwitterionic materials, high-performan...
