“…Conjugated polyelectrolytes have gained much attention in the optoelectronics research field owing to their better carrier transporting capability, pH neutrality, low cost, and excellent film-forming property. 144,145 Lu et al 146 synthesized four conjugated polyelectrolytes namely, PCP-Li, PCP-Na, PCP-2F-Li, and PCP-2F-Na, and studied the impact of fluorination on the work function of anode interlayer. In comparison with the work function of PCP-Na (4.86 eV), a noticeable enhancement in the work function of PCP-2F-Na (4.97 eV) was observed.…”

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.

“…Comparatively, conducting polymers (CPs) have unique advantages, such as good conductivity, good energy storage capacity, large voltage window, and multicolor, which are considered as an attractive option for electrochromic supercapacitors. , Among various CPs, polythiophene has higher conjugated electron cloud density than polypyrrole and polyaniline, which displays superior electrochemical performance. , Especially, when introducing ethylenedioxy, poly(3,4-ethylenedioxythiophene) (PEDOT) possesses higher conductivity, lower oxidation potential, lower band gap, and better environmental stability, due to the outstanding electrochemical performance of CPs. , However, PEDOT and their derivatives often suffer from poor stability because the charge–discharge process and the overoxidation degradation can cause swelling and shrinking, which limits their application in some degree. According to the literature, this is mainly that the inner of polymers is not fully used. − It is an effective method to obtain the desired polymer microstructure by changing the molecular structure because the molecular twist is usually changed by introducing side chains or complexing with other materials. But, the planar molecular conformation makes the polymers easily undergo compact aggregation, which does not fundamentally solve the internal utilization of PEDOT. , Thus, it is invaluable to propose an effective design strategy that can improve the stability of CPs containing PEDOT.…”

In view of that conducting polymers (CPs) have potential application in an energy storage system but suffer from poor stability during the charge−discharge process, we proposed a molecular expansion strategy to guide the design of stable electrochromic supercapacitors in this work. Two polymers P(BT-4Th) and P(BT-4EDOT) with a three-dimensional (3D) network structure were prepared by electrochemical polymerization in the neutral (DCM/ACN (v/v = 1:1) with 0.1 mol L −1 Bu 4 NPF 6 ) and acidic (boron trifluoride ether (BFEE)) system. Comparatively, P(BT-4EDOT) with a good 3D porous structure that fully utilizes its exposed active sites exhibited both good electrical properties and excellent stability, including 55% optical contrast in the visible region, within 1 s response time, 355 cm 2 C −1 coloration efficiency, 210 F g −1 specific capacitance, and 92% capacitance retention after 2000 cycles. The P(BT-4EDOT)-based electrochromic-supercapacitor device (ESD) also exhibited good capacitive performance (66 F g −1 ) and excellent stability (85.26% after 1000 cycles). Excitingly, the energy storage level of ESD could be directly monitored through color changes. All of these results showed that the 3D network structure can dramatically improve the internal utilization of CPs and thus improve their stability. And the molecular expansion strategy will spark ideas for the construction of high-stable ESD based on CPs.
