Thin films of nanocomposite blended solid polymer electrolyte consisting of polymethyl methacrylate (PMMA)/polyvinylidene fluoride (PVDF), potassium iodide (KI) and iodine (I2) as redox couple and pyrazole (PYR) as dopant were prepared using solution casting technique. The consequences of inclusion of PYR within PMMA/PVDF/KI/I2 were investigated in terms of photovoltaic performance of the cell whereas the PYR impregnated polymer electrolyte solution when introduced into dye-sensitized solar cells (DSSCs) exhibited an overall energy-conversion efficiency of 5.5% at room temperature under AM1.5 illumination.
