AB  - In the present work, phthaloyl chitosan (PhCh)-based gel polymer electrolytes 
      (GPEs) were prepared using dimethylformamide (DMF) as a solvent, ethyl carbonate 
      (EC) as a co-solvent, and a set of five quaternaries of potassium iodide (KI) as 
      a doping salt, which is a mixed composition of iodine (I(2)). The prepared GPEs 
      were applied to dye-sensitized solar cells (DSSC) to observe the effectiveness of 
      the electrolyte, using mesoporous TiO(2), which was sensitized with N3 dye as the 
      sensitizer. The incorporation of the potassium iodide-based redox couple in a 
      polymer electrolyte is fabricated for dye-sensitized solar cells (DSSCs). The 
      number of compositions was based on the chemical equation, which is 1:1 for 
      KI:I(2). The electrical performance of prepared GPE systems have been assessed 
      using electrical impedance spectroscopy (EIS), and dielectric permittivity. The 
      improvement in the ionic conductivity of PhCh-based GPE was observed with the 
      rise of salt concentration, and the maximum ionic conductivity (4.94 x 10(-2) S 
      cm(-1)) was achieved for the 0.0012 mol of KI:I(2). The study of dielectric 
      permittivity displays that ions with a high dielectric constant are associated 
      with a high concentration of added ions. Furthermore, the gel polymer electrolyte 
      samples were applied to DSSCs to detect the conversion effectiveness of the 
      electrolytes. For electrolytes containing various content of KI:I(2) the highest 
      conversion efficiency (eta%) of DSSC obtained was 3.57% with a short circuit 
      current density (Jsc) of 20.33 mA cm(-2), open-circuit voltage (Voc) of 0.37 V, 
      fill factor (FF) of 0.47, as well as a conductivity of 2.08 x 10(-2) S cm(-1).
