“…Turmeric is a natural dye containing betaxanthin pigment, which produces a yellowish orange [32]. To optimize the betaxanthin extraction, the suitability degree of 3 solvents with different polarities was investigated, namely [33]. Turmeric extract with distilled water showed absorbance at 502.3 nm (0.523), while 484.3 nm (0.744) and 462.3 nm (0.735) were indicated by methanol and ethanol, respectively.…”

The potential of dye-sensitized solar cells (DSSC) as an alternative to depleting fossil fuels has been investigated. To optimize performance and efficiency, the effectiveness of PVDF and PVDF nanofiber (NF) membrane-based electrolytes in suppressing solvent leakage and evaporation in liquid electrolyte systems was evaluated. SEM results for PVDF NF membranes showed the formation of a network with a three-dimensional structure with a diameter of 100–300 nm and an average thickness of 0.14 mm. The Infrared (IR) spectrum shows the electrolyte and polymer-PVDF interactions. Differential Scanning Calorimetry (DSC) curve shows the melting transition of PVDF NF 7.66% lower than PVDF. Efficiency and resistance of DSSC based on natural dyes as measured by multimeter and Electrochemical Impedance Spectroscopy (EIS) at a solar intensity of 100 mW/cm2 showed the highest efficiency of anthocyanin-based DSSC from telang (Clitoria ternatea L.) flower extract. Its use as a photosensitizer in an electrolyte system based on PVDF NF membranes resulted in an efficiency that was not significantly different from that of liquid electrolytes (1.69%).

“…DSSC based on SPE is fabricated by sandwiching an SPE film between the photoanode and counter electrode. SPEs based on polymer hosts such as poly(methyl methacrylate) (PMMA), poly(ethylene oxide) (PEO), polyurethane (PU), and poly(vinylidinefluoride‐ co ‐hexafluoropropylene) (PVDF‐HFP) have been reported. To the best of our knowledge, there is no report on poly(methyl acrylate) (PMA)‐ and poly(vinyl acetate) (PVAc)‐based SPE for application in DSSC.…”

Poly(methyl acrylate) (PMA)-tetrapropylammonium iodide (TPAI) and poly(vinyl acetate) (PVAc)-TPAI solid polymer electrolytes were prepared by solution casting method. DSC, FTIR, and conductivity results are reported. TPAI interacts with PMA and PVAc to form PMA-TPAI and PVAc-TPAI complexes. Formation of PMA-TPAI and PVAc-TPAI complexes are supported by the DSC and FTIR studies. Linear relationship for the dependence of glass-transition temperature, T g , on salt concentration allows the estimation of the complexation extent between polymer and salt. A greater extent of complexation for PMA with TPAI is observed and correlated with the FTIR results. The conductivities achieved at 15 wt % of TPAI for PMA and PVAc are 2.6 × 10 −11 and 1.3 × 10 −11 S cm −1 , respectively. Higher dielectric constant and lower T g of PMA result in higher number and mobility of ions, which lead to higher conductivity in accordance with σ = enμ. All-solid-state dye-sensitized solar cells (DSSCs) were assembled with PMA-TPAI and PVAc-TPAI electrolytes. DSSC efficiencies achieved for PMA and PVAc are 2.41% and 2.05%, respectively. Better performance of DSSC with PMA electrolyte is attributed to higher short-circuit current density, J sc , and lower recombination loss. Lower J sc , higher recombination loss, and degradation of counter electrode are the reasons for DSSC degradation.
