The use of bio liquid electrolytes in solar cells enhances cell performance, minimises electrostatic charge on the surface, and reduces the possibility of solid electrolyte leakage. In addition to yellow dye produced from flowers, the goal of the study is to make a liquid electrolyte of polyvinyl alcohol. To make varied amounts of dye, the yellow dye from flowers growing in Carthage, Tunisia, was extracted using acetone and diluted with ionised water. The dye molecules act as a light collector and are created by the excitation of electrons. Polyvinyl alcohol was dissolved in 100 ml of various solvents (water, diluted dye, and concentrated dye) to achieve a constant concentration of 0.01 g / ml in all solutions. Optical parameters such as absorbance, transmittance, and energy gap were investigated utilising the ultraviolet spectrum. The optical qualities, such as absorbance and absorption coefficient, rose as the dye concentration grew, but transmittance reduced as the pigment concentration increased. The energy gap shrinks as the dye concentration rises, reaching a minimum of roughly 1.7 eV at the concentrated dye. When the concentrated dye is added to the polyvinyl alcohol, however, the energy gap shrinks from 4 eV to 1.8 eV.
