Solid-state photovoltaic devices based on perylene acid-sensitized nanostructural SnO2 with P(VdF-co-HFP) gel electrolyte

The characteristics of perylene acid sensitized tin oxide photovoltaic device with gel polymer system made of a free standing film of poly(vinylidene fluoride-co-hexafluoropropylene) as an solid-state electrolyte were studied. The photovoltaic device composed of ITO/perylene Acid-SnO2/gel polymer electrolyte/Pt structure showed a short circuit photocurrent density of 2.5 mA/cm2, an open circuit photovoltage of 0.28 V, a fill factor of 0.51 and an overall power efficiency of 0.36% under illumination of white Xe light with an intensity of 100 mW/cm2. The influence of plasticizer additive on the ionic conductivity of gel polymer electrolyte was also studied.
