Dye-sensitized solar cells (DSSCs) have gained attention not only for their potential in IoT technology
and ambient light harvesting but also for their role in enhancing energy efficiency across the information
and communication technology (ICT) landscape. The challenges faced by DSSCs, such as leakage and
sealing issues with their liquid electrolytes, have hindered their industrial fabrication. To address this
problem, quasi-solid-state (QS) gel polymer electrolytes have emerged as a promising solution, despite
their initial limitations related to low conductivity and ion transfer rates [1-2]. Ti3C2 MXene with a unique
two-dimensional layer structure [3] can be utilized as a gel polymer-based electrolyte due to its high
conductivity, high electrochemical properties, and anisotropic charge transfer to improve DSSCs
performance [4]. Integrating Ti3C2 MXene into a copper complex (Cu)-based redox shuttle within the gel
polymer matrix introduces a novel QS-electrolyte, addressing liquid electrolyte limitations while enhancing
conductivity, reducing charge transfer resistance, and increasing short current density (JSC) during light
soaking for improved QS-DSSC performance. This innovative approach holds potential for improving charge
transfer and facilitating the diffusion of electrolyte ions, thereby enhancing the performance of DSSCs
fabrication within the context of sustainable technologies for renewable energy applications
