“…As an example, in terms of materials selection, a highly ambitious challenge would be the replacement of the oil-derived polymer matrixes by means of biosourced ones. 57,[323][324][325][326] In the field of water-based DSSCs, a first attempt has been proposed by Kaneko and coworkers, who reported that polysaccharides such as agarose and k-carrageenan 327 can form a tight and elastic solid able to retain the aqueous electrolyte (LiI 0.10 M and I 2 10 mM in H 2 O, pH 2). 328 Detachment of the N3 dye from the TiO 2 electrode was not observed even after prolonged irradiation times; moreover EIS analysis showed that the electron donation from the I À to the oxidized sensitizer took place in a similar way both in the quasi-solid and in the liquid state.…”

Nowadays, dye-sensitized solar cells (DSSCs) are the most extensively investigated systems for the conversion of solar energy into electricity, particularly for implementation in devices where low cost and good performance are required. Nevertheless, a key aspect is still to be addressed, being considered strongly harmful for a long time, which is the presence of water in the cell, either in the electrolyte or at the electrode/electrolyte interface. Here comes the present review, in the course of which we try our best to address the highly topical role of water in DSSCs, trying to figure out if it is a poisoner or the keyword to success, by means of a thoroughly detailed analysis of all the established phenomena in an aqueous environment. Actually, in the last few years the scientific community has suddenly turned its efforts in the direction of using water as a solvent, as demonstrated by the amount of research articles being published in the literature. Indeed, by means of DSSCs fabricated with water-based electrolytes, reduced costs, non-flammability, reduced volatility and improved environmental compatibility could be easily achieved. As a result, an increasing number of novel electrodes, dyes and electrolyte components are continuously proposed, being highly challenging from the materials science viewpoint and with the golden thread of producing truly water-based DSSCs. If the initial purpose of DSSCs was the construction of an artificial photosynthetic system able to convert solar light into electricity, the use of water as the key component may represent a great step forward towards their widespread diffusion in the market.

“…Quite a few challenges still remain before its commercialization, including cost, performance and 22 long-term stability. So far, various strategies are carried out to develop the low-cost, stable, and particularly highly efficient materials for different parts of DSSC, including the molecular engineering of novel dye sensitizers [126][127][128][129][130], the development of new redox shuttles [131][132][133][134][135][136], the construction of porous TiO 2 [137][138][139][140], and the search for low-cost, highly stable and catalytic CE materials [22,41,58,141]. Among the strategies for exploring new Pt-free CE materials, the family of carbon CE materials has become one of hot issues in photovoltaic research due to their low cost, anti-corrosion and high catalytic activity.…”

“…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 %.
