Solar radiation offers benefits such as sustainability, renewability, and environmental friendliness. Furthermore, solar energy can generate multiple forms of energy. Over the past 30 years, the use of dye-sensitized solar cells (DSSCs) has been extensively investigated due to their simple manufacturing process, low cost, and excellent energy conversion and storage capabilities. In this work, a DSSC was fabricated with a poly(ethyl methacrylate) (PEMA) polymer electrolyte impregnated with an iodide-based ionic liquid. The influence of the ionic liquid on the interfacial characteristics and overall efficiency of the DSSCs with this polymer electrolyte was examined. The ionic liquid-doped polymer electrolyte exhibits an ionic conductivity of 1.27 × 10⁻⁴ S/cm at 40 wt% at room temperature. The DSSC has a conversion efficiency of 1.47% under one-sun conditions. The incorporation of the ionic liquid demonstrated improved stability and efficiency in photovoltaic power generation. © The Author(s) 2026.
