Preparation and characterization of PAN based solid polymeric electrolyte for dye-sensitized solar cells

Fabrication and characterization of a solid polymeric electrolyte of PAN‐TiO2‐LiClO4

“…It was observed that the highest conductivity obtained is 1.8 × 10 −4 S cm −1 at TiO 2 concentration of 7.5 wt %. This result is comparable with the electrolyte with PC plasticizer showing a maximum room temperature conductivity of 4.2 × 10 −4 S cm −1 obtained at 10 wt % of LiClO 4 by Rika et al6 The result is also comparable with the maximum room temperature conductivity of PVdF‐LiClO 4 ‐TiO 2 that was 7.1 × 10 −4 S cm −1 obtained at 10 wt % TiO 2 11. The lowest value of conductivity is 5.6 × 10 −5 S cm −1 at TiO 2 concentration of 12.5 wt %.…”

“…These values are accurate because the correlation factor of the linear adjustment is very close to 1. Those obtained from the electrolyte system with PC plasticizer were 2.0 × 10 −4 S cm −1 and 0.46 eV 6. The σ 0 is comparable but not for E a .…”

“…As such, many polymer electrolyte systems with different combinations of filler and salts have been developed 2‐5. In an earlier work on a polymer electrolyte based on PAN doped with PC plasticizer, a room temperature ionic conductivity as high as 4.2 × 10 −4 S cm −1 was obtained by Rika et al6 PAN‐based solid polymeric electrolyte has been developed by a lot of groups such as Forsyth et al, Yang et al, and Lewandowski and Stepniak 7–9. Ahmad et al10 has chosen a TiO 2 filler to be blended into a composite solid electrolyte of PVC‐LiClO 4 for the ionic conductivity enhancement as it is a stable semiconductor filler.…”

Review on polymer electrolyte in dye-sensitized solar cells (DSSCs)

“…They consist of a variety of classical polymeric materials from synthetics polymer and its blends to bio-based polymer. Namely, PEO (Ren et al, 2002), poly (methyl methacrylate) (PMMA) (Lee et al, 2010e;Yang et al, 2008), polyethylene glycol (PEG) (Joseph et al, 2006), poly(ethylene glycol) methyl ether methacrylate (PEGMA) (Bella et al, 2013a(Bella et al, , 2013b, polyacrylonitrile (PAN) (Taslim et al, 2010;Rika et al, 2009;Rahman et al, 2010), poly(vinyl chloride) (PVC) (Rahman et al, 2004(Rahman et al, , 2007, and poly(vinylidene fluoride-co-hexafluoropropylene) (PVdF-HFP) Lee et al, 2008b;Priya et al, 2008;Noor et al, 2014). To date, polysaccharides and modified polysaccharides based materials such as chitosan (Buraidah et al, 2010), cellulose (Rudhziah et al, 2015) and carrageenan (Bella et al, 2015) received the attention due to their higher ionic conductivities at room temperature.…”

Conductivity studies of poly(ethylene oxide)(PEO)/poly(vinyl alcohol) (PVA) blend gel polymer electrolytes for dye-sensitized solar cells

“…Many types of polymers have been applied in the polymer electrolyte systems for DSSCs, including polyacrylonitrile (PAN) [10], poly(vinylidene fluoride) (PVDF) [11], polyvinylidene fluoride-poly(methyl methacrylate) (PVDF-PMMA) [12], poly(ethylene oxide)-poly(methyl methacrylate) (poly(ethylene oxide)(PEO)-PMMA) [13], and polyvinyl butyral (PVB) [14], to name a few. These polymers have been mixed with various salts to provide ions for conduction.…”
