Özet

In this work, natural dye-sensitized solar cells (N-DSSCs) sensitized with Parthenocissus quinquefolia L. (PQ) extract were fabricated using three distinct redox electrolyte systems (EL1, EL2, and EL3) to examine electrolyte effects. The device containing EL3 exhibited the highest power conversion efficiency of 0.72%, with improved fill factor and recombination resistance due to suppressed charge recombination and extended electron lifetime. Our findings highlight the critical role of electrolyte engineering in enhancing anthocyanin-based N-DSSC performance.
