“…have been used as fillers in electrolytes for dye-sensitized solar cell applications [27][28][29][30][31][32][33][34][35][36][37][38]. Among them, TiO 2 nanoparticles are considered as one of the most promising fillers because of their availability in nature, UV resistance, photocatalytic activity for pollutant removal, photoelectrochemical conversion, and anti-bacterium properties and polymorph crystalline structures like anatase, brookite, and rutile [39,40].…”

The hybrid polymer nanocomposites based on poly(vinylidene fluoride-co-hexaflouro propylene) (PVdF-HFP) as a host matrix, propylene carbonate as the plasticizer, and surface modified and unmodified TiO 2 nanoparticles as fillers for dye-sensitized solar cell applications have been prepared using a solvent casting technique. The surface of TiO 2 was modified using aminopropyltrimethoxysilane (APS), and its organic functional groups on TiO 2 were confirmed by Fourier transform infrared (FTIR) spectroscopy. The PVdF-HFP membranes were characterized by FTIR, wide-angle X-ray diffraction (WAXD), differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), atomic force microscopic (AFM), and ultraviolet-visible (UV-Vis) spectroscopic techniques. It was found a new interaction of APS molecules on TiO 2 surface with matrix as well as electrolyte salt. The experimental observations indicated a noticeable improvement in ionic conductivity of modified TiO 2 of about 6.7×10 −4 S/cm when compared with unmodified counterpart (TiO 2 ) as the filler within PVDF-HFP matrix. The solid state dye-sensitized solar cell has been fabricated by using silanemodified TiO 2 /PVdF-HFP nanocomposite electrolyte and eosin-Y as sensitizer, and its photoconversion efficiency is measured about 1.47 %.

“…Well known as a catalytic reagent for sugar hydrolysis, human papilloma virus (HPV) infection inhibitor, and used in the preparation of hydrogels for drug-delivery and superabsorbent materials, it was introduced in the field of solar energy harvesting by Bella and co-workers (31). Starting from the raw material ( C, extracted from Eucheuma cottonii seaweeds by a low cost industrial process), C was converted into carboxymethylated C (C C), since the introduction of oxygen-containing substituent groups in the C chain can provide more sites for cations to coordinate, thus increasing the ionic conductivity with respect to the raw material.…”

Glass GlassHowever, despite the record efficiency of 14.3% and the recent large-scale industrial production, DSSCs still depend on oil-derived electrolytes and nanostructured electrodes designed by expensive templating agents.This trend is changing, and in recent years the scientific community has started to propose natural polymers as substitutes for the more expensive and oil-derived materials. In this article, we present some electrolytes and electrodes developed with these new materials and demonstrate how the DSSC device is gradually approaching the highly cited and mentioned artificial leaf.
