“…As shown in Figure S1 , the water and EG contact angles were 105.6° and 77.9°, respectively. The surface energy of the pure F 16 CuPc film was calculated as 25.97 mN/m, based on the Owens–Wendt–Kaelble equation as shown in Equations (1) and (2) [ 36 ]. The surface energies were calculated based on the WCA and EG contact angle (EGCA).…”

Superhydrophobicity is the phenomenon of which the water contact angle (WCA) of droplets on a solid surface is greater than 150°. In the present paper, we prepare a superhydrophobic film with a structure similar to the surface of a lotus leaf, which is composed of polydimethylsiloxane (PDMS), zinc oxide (ZnO), a molecular sieve (MS) and 1,2,3,4,8,9,10,11,15,16,17,18,22,23,24,25-hexadecafluorophthalocyanine copper(II) (F16CuPc). The F16CuPc was used as the modifier to reduce the surface energy of the biomimetic micro-nanostructure. With the introduction of F16CuPc, the superhydrophobic properties of the surface were enhanced so that the WCA and water roll-off angle could reach 167.1° and 0.5°, respectively. Scanning electron microscopy, X-ray energy spectrometry, and X-ray photoelectron spectroscopy analyses verified that the enhanced superhydrophobic properties of the film were mainly attributed to the modification of F16CuPc. Finally, thermal, mechanical, and chemical stability studies, as well as the influences of UV and underwater immersion on the superhydrophobic film were investigated. This developed two-step fabrication method may be a potential direction for superhydrophobic surface fabrication due to its simple process, excellent superhydrophobic property, and favorable stability.

“…Recently, Lian et al 187 reported MoSe 2 /PEDOT:PSS bilayer hole transporting layer in NF‐OSCs. The obtained results showed that bilayer AIL could effectively change the work function of PEDOT:PSS and molecular orientation of BHJ, leading to improve the fill factor, short circuit density, and efficiency.…”

Recently, the power conversion efficiency (PCE) of single-junction non-fullerene polymer solar cells (NF-PSCs) has surpassed 19% due to the fast development of novel donor polymers, NF-acceptors, device engineering, and interlayer materials.The anode interlayer (AIL) plays a vital role in improving the efficiency and stability of PSCs. The challenges and opportunities in this research area encourage researchers to pursue great innovation in developing new materials and strategies for highly efficient NF-PSCs. This review summarizes the recent development of AIL materials and their modification strategies in single-junction NF-PSCs. Firstly, a brief introduction, key functions, basic requirements, and peculiar features of AILs when employed in NF-PSCs are discussed. Then, the impact of AIL materials (including organic, inorganic, and hybrid materials) on the PCE and the stability of NF-PSCs are described. Afterward, the fabrication of large-area devices and related issues are highlighted. The summary and the future challenges regarding efficient AIL are summarized in the last section of this review.

“…Lian et al. inserted MoSe 2 in between PEDOT:PSS and ITO electrode, which reduced the charge recombination and enhanced the charge extraction and transport due to its well‐matched WF and superior conductivity [71] . Mover, the device stability was significantly improved because the MoSe 2 QD interlayer could prevent PEDOT:PSS from corroding the ITO electrode and remove the partial PSS from the interface of the HTL and active layer.…”

Nonfullerene acceptor based organic solar cells (NF‐OSCs) have witnessed rapid progress over the past few years owing to the intensive research efforts on novel electron donor and nonfullerene acceptor (NFA) materials, interfacial engineering, and device processing techniques. Interfacial layers including electron transporting layers (ETL) and hole transporting layers (HTLs) are crucially important in the OSCs for facilitating electron and hole extraction from the photoactive blend to the respective electrodes. In this review, the lates progress in both ETLs and HTLs for the currently prevailing NF‐OSCs are discussed, in which the ETLs are summarized from the categories of metal oxides, metal chelates, non‐conjugated electrolytes and conjugated electrolytes, and the HTLs are summarized from the categories of inorganic and organic materials. In addition, some bifunctional interlayer materials served as both ETLs and HTLs are also introduced. Finally, the prospects of ETL/HTL materials for NF‐OSCs are provided.
