Supercapacitor energy storage devices are well suited to meet the rigorous demands of future portable consumer electronics (PCEs) due to their high energy and power densities (i.e., longer battery-life and rapid charging, respectively) and superior operational lifetimes (10 times greater than lithium-ion batteries). To date, research efforts have been narrowly focused on improving the specific capacitance of these materials; however, emerging technologies are increasingly demanding competitive performance with regards to other criteria, including scalability of fabrication and electrochemical stability. In this regard, we developed a polyaniline (PANI) derivative that contains a carbazole unit copolymerized with 2,5-dimethyl-p-phenylenediamine (Cbz-PANI-1) and determined its optoelectronic properties, electrical conductivity, processability, and electrochemical stability. Importantly, the polymer exhibits good solubility in various solvents, which enables the use of scalable spray-coating and drop-casting methods to fabricate electrodes. Cbz-PANI-1 was used to fabricate electrodes for supercapacitor devices that exhibits a maximum areal capacitance of 64.8 mF cm −2 and specific capacitance of 319 F g −1 at a current density of 0.2 mA cm −2 . Moreover, the electrode demonstrates excellent cyclic stability (≈ 83% of capacitance retention) over 1000 CV cycles. Additionally, we demonstrate the charge storage performance of Cbz-PANI-1 in a symmetrical supercapacitor device, which also exhibits excellent cyclic stability (≈ 91% of capacitance retention) over 1000 charge−discharge cycles.

“…Recently, Huang et al. employed diphenylaminesulfonic acid sodium (DAS) as the raw material and prepared poly(diphenylamine‐4‐sulfonic acid) (PDAS) by one‐step polymerization process, which did not require additional anions for doping and equipped with excellent solution processability [73] . Compared with PEDOT:PSS, PDAS exhibited satisfactory structural and electrical homogeneity, high conductivity (7.75×10 −2 S cm −1 ), neutral pH and enhanced WF (5.43 eV).…”

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.

The development of universal interlayer materials for diverse optoelectronic devices not only decreases the costs in both laboratory research and industrialized production, but also improves the uniformity of different devices so as to facilitate device integration. However, using one material to fabricate diverse devices remains a great challenge. Herein, p‐π conjugation is utilize to replace the commonly used π–π conjugation to develop an unprecedented anode interlayer (AIL) material PCP‐S that can be universally used in diverse optoelectronic devices, including organic light‐emitting diode (OLED), organic solar cell (OSC), and perovskite solar cell (PSC). The unique solubility and the easy adjustment of optoelectronic properties are keys to realize the multiple uses of PCP‐S. First, OSC based on the polyoxometalate (POM)‐doped PCP‐S exhibits a high power conversion efficiency (PCE) of 17.1%, representing the highest efficiency for OSCs using a solution‐processed pH‐neutral AIL. Second, PSC with PCP‐S shows a PCE of 20.1%, which is superior to the device with poly(triaryl amine) (PTAA). Third, OLED possesses a significantly reduced turn‐on voltage from 3.8 to 2.8 V by incorporating the PCP‐S AIL. To the best of the authors’ knowledge, this is the first example of a universal AIL material to realize multiple applications.
