“…It may be possibly used for R2R processing due to its better thickness insensitivity. Jeong et al 239 inserted small molecule electrolyte (C6‐E‐OTs) hybridized ZnO in OSCs as CIL. The device with C6‐E‐OTs hybridized ZnO as CIL showed a relatively higher PCE of 8.8% as compared to 7.6% (bare ZnO).…”

Non‐fullerene acceptors are currently a hot research area in the development of organic solar cells (OSCs). At present, the‐state‐of‐the‐art power conversion efficiency (PCE) of non‐fullerene organic solar cells (NF‐OSCs) with single and multiple‐junction has surpassed 18% and 19%, respectively. The cathode interlayer (CIL) plays a significant role in the improvement of PCE and the stability of OSCs. Recently, a large number of CIL materials have been employed in OSCs. This review summarizes the recent progress of CIL materials and systematically describes their impact on the device efficiency and stability in single‐junction NF‐OSCs. Firstly, the functions, key requirements, and distinctive features of CILs when used in NF‐OSCs are summarized. Afterward, some big families of materials including metal oxides, metal salts/complexes, small molecules, polymers, composites/hybrids are presented as CIL for NF‐OSCs. Finally, the scale‐up techniques, conclusion, and future challenges regarding CIL in NF‐OSCs are elucidated.

“…The use of new acceptors led to higher performance when compared to FA organic solar cells but, beyond the photoactive film, other fundamental layers in solar cells are the anode interlayer (AIL) and the cathode interlayer (CIL), needed to improve device performance. Indeed, these are an effective tool to optimize charge extraction selectivity and to reduce recombination and contact resistance [13][14][15][16]. The increasing number of photoactive materials opens the urgent request to find universal interlayers for PSCs, efficient for a wide range of materials and thickness insensitive [17][18][19].…”

Polymer solar cells (PSCs) based on non-fullerene acceptors have the advantages of synthetic versatility, strong absorption ability, and high thermal stability. These characteristics result in impressive power conversion efficiency values, but to further push both the performance and the stability of PSCs, the insertion of appropriate interlayers in the device structure remains mandatory. Herein, a naphthalene diimide-based cathode interlayer (NDI-OH) is synthesized with a facile three-step reaction and used as a cathode interlayer for fullerene and non-fullerene PSCs. This cationic polyelectrolyte exhibited good solubility in alcohol solvents, transparency in the visible range, self-doping behavior, and good film forming ability. All these characteristics allowed the increase in the devices’ power conversion efficiencies (PCE) both for fullerene and non-fullerene-based PSCs. The successful results make NDI-OH a promising cathode interlayer to apply in PSCs.
