“…So far, the maximum efficiency of DSSC about 11-12 % has been reported by using liquid electrolyte and ruthenium dyes [3]. But, the major disadvantages of these solar cells is leakage of solvent and high temperature instability, dye desorption, electrode corrosion which causes the sealing and performance degradation of DSSCs [4]. Many attempts have been focusing on durability and to replace the liquid electrolyte medium by using solid p type inorganic materials, organic hole conductors, ionic liquids and gel/solid polymer electrolytes [5][6][7][8].…”

Poly ethylene oxide (PEO) and Polyvinylidene fluoride-co-hexaflouropropylene (PVdF-HFP) blend electrolytes filled with surface modified TiO 2 nanofillers were prepared by solvent casting method. The ionic conductivity is increased about 7.02 9 10 -4 S/cm with the incorporation of surface modified TiO 2 nanoparticles upto 7 wt %, where the ionic conductivity was about 7.94 9 10 -5 S/cm with the addition of unmodified counterpart as the filler within PEO/PVdF-HFP blends. Similarly, ionic mobility, charge carrier concentration, ion diffusion coefficient also found to increase with the addition of surface modified TiO 2 nanoparticles. XRD results showed the change in the crystalline phase of PEO/PVdF-HFP blend electrolyte with the addition of surface modified TiO 2 . The effect of the TiO 2 nanoparticles surface functionality on the degree of crystallinity of the polymer matrix was analyzed using DSC. The distribution of nanoparticles within the PEO/PVdF-HFP was studied by SEM. The solid state dye sensitized solar cell has been fabricated by using silane modified TiO 2 /PEO/PVdF-HFP polymer nanocomposites electrolyte and natural dye extracted from gross as a sensitizer. The current-voltage characteristics of solar cells showed an enhancement of open circuit voltage (V oc ) from 0.31 to 0.47 V and the best fill factor achieved about 64 %, when silane modified TiO 2 is added.

“…3 However, the major drawback of these solar cells is leakage of solvent and high temperature instability, dye desorption, electrode corrosion which causes the sealing and performance degradation of DSSCs. 4 To overcome these problem for commercial exploitation of DSSC; many efforts have been focusing on long term stability and to replace the liquid electrolyte medium by using solid p type inorganic materials, organic hole conductors, ionic liquids and gel/solid polymer electrolytes. [5][6][7][8] Among these alternatives, solid polymer electrolytes (SPEs) have received considerable attention, because of their outstanding performance in solid-state batteries, electrochromic devices, fuel cell and photoelectrochemical cells were extensively studied.…”

Polymer blend electrolyte membrane was prepared for dye sensitized solar cells based on poly ethylene oxide and polyvinylidene fluoride-co-hexaflouropropylene (PVDF-HFP) filled with surface modified Titanium dioxide (M-TiO 2 ) nanofillers. The surface of TiO 2 was modified using Aminopropyltrimethoxysilane. The electrochemical studies indicated that the addition of surface modified nanoparticles increase the ionic conductivity up to 7.21x 10 -4 S/cm for 7 wt%, whereas the ionic conductivity about 8.14×10 -5 S/cm with the addition of unmodified counterpart as the filler into the PEO/PVDF-HFP blend system. In addition to this ionic mobility, charge carrier concentration, ion diffusion coefficient also found to increase with the addition of surface modified TiO 2 nanoparticles. Wide angle X-ray diffraction (WAXD) results showed the change in the crystalline phase of PEO/PVDF-HFP blend electrolyte with the addition of M-TiO 2 . The influence of the TiO 2 nanoparticles surface functionality on the degree of crystallinity of the polymer matrix was analyzed using differential scanning Calorimetry (DSC). Thermo mechanical behavior of the composite membranes was studied by dynamical mechanical Analysis (DMA). The thermo gravimetric investigations (TGA) of membranes indicated the thermal degradation temperatures of hybrid nanocomposites were enhanced upon the addition of nanosized inorganic fillers. The morphological characterizations were carried out by atomic force microscopy (AFM). The solid state dye sensitized solar cell has been fabricated by using silane modified TiO 2 /PEO/PVDF-HFP polymer nanocomposites electrolyte, multiwalled carbon nanotube (MWCNT)/Nafion ® as counter electrode. The photovoltaic characteristics of constructed cells showed an enhancement of open circuit voltage (V oc ) from 0.62 to 0.71 V andthe best efficiency achieved about 2.84%. The enhancement of DSSC was further confirmed by electrochemical impedance spectra (EIS) spectra studies for lowest Warburg resistance (R diff ).

In this study, photovoltaic (PV) properties of dyesensitized solar cells (DSSCs) incorporated with graphene oxide nanosheet-polyaniline (GOS-PANI) nanohybrid/poly(ethylene oxide) (PEO) blend gel electrolytes were investigated. Chemical structure and composition of GOS-PANI nanohybrids were characterized by Raman spectroscopy and X-ray photoelectron spectroscopy. The images of transmission electron microscopy revealed that PANI nanorods were anchored to the single-layered GOS for the GOS-PANI nanohybrids. Ionic conductivities of the GOS-PANI/PEO-based gel electrolytes were measured using a conductivity meter. The electrochemical catalytic activities of the GOS-PANI nanohybrids were determined through cyclic voltammetry. These GOS-PANI nanohybrids were served as the extended electron transfer materials and catalyst for the electrochemical reduction of I 3 2 . Due to the enhancement of the ionic conductivity and electrochemical cat-alytic activity of the gel electrolyte, better PV performance was observed for the DSSCs based on the GOS-PANI containing electrolytes as compared to the pristine PEO electrolyte-based DSSC sample. Moreover, PV performances of the GOS-PANI/ PEO-based DSSCs were closely related to the PANI content of GOS-PANI nanohybrids. The highest photo-energy conversion efficiency (5.63%) was obtained for an optimized GOS-PANI/PEO (5:95, w/w) blend gel electrolyte-based DSSC sample.
