“…The oxidation of MXene under high‐temperature and humid environments can be prevented by introducing positive metal ions on the MXene nanosheets because metal ions readily bond with oxygen‐containing groups. Compared to Ag and Ni, Zn has higher reactivity, [ 22 ] less deformability, better flexibility, and higher transparency. [ 23 , 24 ] To utilize Ti 3 C 2 T x MXene as an FTCE, we sandwiched a thin Ag layer between the MXene layers and achieved a window of WF ranging from 4.61 to 5.08 eV, which provided positive and negative changes in the WF of the MXene.…”

Hybrid systems have attracted significant attention within the scientific community due to their multifunctionality, which has resulted in increasing demands for wearable electronics, green energy, and miniaturization. Furthermore, MXenes are promising two‐dimensional materials that have been applied in various areas due to their unique properties. Herein, a flexible, transparent, and conductive electrode (FTCE) based on a multilayer hybrid MXene/Ag/MXene structure that can be applied to realize an inverted organic solar cell (OSC) with memory and learning functionalities is reported. This optimized FTCE exhibits high transmittance (84%), low sheet resistance (9.7 Ω sq−1), and reliable operation (even after 2000 bending cycles). Moreover, the OSC using this FTCE achieves a power conversion efficiency of 13.86% and sustained photovoltaic performance, even after hundreds of switching cycles. The fabricated memristive OSC (MemOSC) device also exhibits reliable resistive switching behavior at low operating voltages of 0.60 and −0.33 V (similar to biological synapses), an excellent ON/OFF ratio (103), stable endurance performance (4 × 103), and memory retention properties (104 s). Moreover, the MemOSC device can mimic synaptic functionalities on a biological time scale. Thus, MXene can potentially be used as an electrode for highly efficient OSCs with memristive functions for future intelligent solar cell modules.

MXenes, a group of two‐dimensional (2D) metal carbides and nitrides, have emerged as promising electrode materials for supercapacitors. This is primarily attributed to their inherent metal‐like electrical conductivity, layered structure, surface redox reactivity, and superior pseudocapacitance through surface functional groups. Owing to its promising features, this material suffers from low mechanical strength, restacking, and unprecedented oxidation. As a result, balancing the electrochemical performance becomes challenging, eventually impeding its potential applications in lightweight, flexible supercapacitor applications. Recent strategies are centered on lighter and more stable filler materials to tackle these issues. Among these, cellulose is considered one of the most effective renewable materials because of its biocompatibility, thermal stability, high surface area, and mechanical reinforcement. Moreover, nanocellulose is capable of hosting other functional materials on its reactive surfaces, ensuring better ion accessibility, and can be used as an electrolyte separator membrane. This review paper aims to provide a comprehensive overview of recent advances in the fabrication strategy, deterministic parameters for capacitive energy‐storage devices, electrochemical behavior, and the performance of MXene/cellulose‐based electrodes in its three‐dimensional aspect (1D, 2D and 3D) for supercapacitor application. Lastly, this review will outline the challenges and prospects of MXene/cellulose‐based composite electrodes in real‐life supercapacitor applications.
