Electrospun polyethylene oxide (PEO) nanofiber membranes based polymer electrolyte for dye sensitized solar cell

Poly (ethyleneoxide) membrane was prepared by electrospinning technique and characterized by HR-SEM, FTIR and XRD analysis. The electrolyte uptake, ionic conductivity and porosity of the membrane were studied. The images revealed that the nanofibers have uniform interconnectivity and no bead formation was observed. The ionic conductivity of gel polymer electrolyte was 1.86 × 10-3 Scm-1 at room temperature. The electrolyte uptake of the membrane reached upto a maximum of ∼94%. The photovoltaic performance of the dye sensitized solar cell using polymer electrolyte was evaluated and reported.
