“…It ensures the charge transport between the two electrodes (photoanode/counter-electrode or photoanode/photocathode) in the electrolyte (classically based on a nitrile solvent). Most of the current research concerning electrolytes is focused on the improvement of long-term stability and the safety of DSSCs through the replacement of the liquid organic solvent-based electrolyte with an aqueous electrolyte, [35] ionic liquids, [36,37] polymer gels [37][38][39] or a membrane, [40,41] solid hole transporting materials (HTMs), [42] etc. In this context, this work aims to investigate, with an exploratory approach, new amphoteric non-toxic and stable sensitizers in order to develop new functionalized nanostructured surfaces that exhibit photo-induced properties.…”

This work explores the potentiality of Mo 6 clusters as new inorganic sensitizers with amphoteric properties for photoelectronic applications being non-toxic and stable. It reports on the design of photoelectrodes by electrophoretic deposition (EPD) of molybdenum octahedral metal cluster iodide (CMI) onto mesoporous TiO 2 and NiO layers before being deposited on FTO (i. e. CMI@TSO@FTO, TSO = TiO 2 or NiO). Indeed, the low-cost, lowwaste and industrially scalable EPD method has allowed for the achievement of transparent,

“…Typical Nyquist’s plots (i.e., real vs imaginary component of impedance Z ) show three semicircles; the lower frequency one is associated with the ionic diffusion throughout the electrolyte. Usually, in QS-DSSCs this semicircle is rather faint 56 due to the slackening of the diffusion kinetics in QS electrolytes. Thus, applied frequencies lower than 1 mHz should be scanned in order to obtain a complete semicircle and a clearer description of the redox shuttle transport phenomenon.…”

In the quest for sustainable materials for quasi-solid-state (QS) electrolytes in aqueous dye-sensitized solar cells (DSSCs), novel bioderived polymeric membranes were prepared in this work by reaction of preoxidized kraft lignin with poly(ethylene glycol)diglycidylether (PEGDGE). The effect of the PEGDGE/lignin relative proportions on the characteristics of the obtained membranes was thoroughly investigated, and clear structure–property correlations were highlighted. In particular, the glass transition temperature of the materials was found to decrease by increasing the amount of PEGDGE in the formulation, indicating that polyethylene glycol chains act as flexible segments that increase the molecular mobility of the three-dimensional polymeric network. Concurrently, their swelling ability in liquid electrolyte was found to increase with the concentration of PEGDGE, which was also shown to influence the ionic transport efficiency within the membrane. The incorporation of these lignin-based cross-linked systems as QS electrolyte frameworks in aqueous DSSCs allowed the preparation of devices with excellent long-term stability under UV–vis light, which were found to be superior to benchmark QS-DSSCs incorporating state-of-the-art carboxymethylcellulose membranes. This study provides the first demonstration of lignin-based QS electrolytes for stable aqueous DSSCs, establishing a straightforward strategy to exploit the potential of lignin as a functional polymer precursor for the field of sustainable photovoltaic devices.

“…Herein, the prepared polymer electrolytes have achieved the maximum ionic conductivity of 1.72 × 10 –3 S cm –1 after the addition of 30 wt % KI salt. Other examples of copolymer commonly used as host polymer in polymer electrolyte are poly(vinylidenefluoride-hexafluoropropylene) (PVDF-HFP), poly(methyl acrylate- co -methylacrylic acid) (P(MMA- co -MAA)), poly(vinyl alcohol- co -ethylene) (PVA- co -PE), and poly(methyl methacrylate- co -ethyl methacrylate) (P(MMA-EMA)). − Seo et al synthesized two types of triblock which have structures of PEG- b -(P(AN- co -BMAAm)) 2 (SGT-602) and PEG- b -(P(AN- co -DMAAm)) 2 (SGT-604) . These triblocks were synthesized via polymerization of poly(ethylene glycol) (PEG), poly(acrylonitrile) (PAN), and two kinds of acrylamides (AAms); N -isobutoxymethyl acrylamide (BMAAm) and N , N ′- dimethyl acrylamide (DMAAm).…”

“…Raman spectroscopy study stated that at 111.4 cm –1 , a strong band, indicates the generation of I 3 – ions in gel electrolytes, and the small band at 143.9 cm –1 assigns to vibration mode of polyiodides species (such as I 5 – ) with 7 wt % showing the highest peak intensity compared to the other electrolytes. , Thus, it has a high ionic conductivity due to the large concentration during the charge transport process, leading to the highest efficiency in their works. Poly(methyl methacrylate- co -methacrylic acid) (P(MMA- co -MAA)) polymer electrolytes containing redox pairs of NaI dopant salt have been reported . This polymer electrolyte achieved a series of the highest conductivity of 1.07 mS cm –1 at 40 wt % NaI and the highest photoconversion efficiency of 2.34%.…”

“…It suggests that the attraction between the anion and cation at a specific amount of redox couple is significant to reduce the gap for I 3 – ions to occur. Thus, there is a reduction in the diffusion coefficient value as there is less tri-iodide ion supply at the counter electrode and a less reduction process of tri-iodide to iodide. , The diffusion of I 3 – does not influence the ionic conductivity but increases I – ions’ number density.…”

Dye-sensitized solar cells (DSSCs) are a suitable replacement for conventional silicon solar cells due to their unique features, such as high energy conversion efficiency and cheap manufacturing cost. The liquid-state DSSCs, however, are poorly sustainable on a long-term basis because volatile liquids are used. The early intention of incorporating polymer into the liquid electrolytes was to curb the problem encountered by liquid electrolytes and enable the DSSCs to function as a long-term stability device. This work briefly reviews how the improvisation has been done on the polymer electrolytes formulation and the extent of how each element can affect the cell efficiency and long-term stability. The role of each component, such as the type of host polymer, iodide salts, nanoparticles, and organic additives that improve the performance of DSSCs, has also been highlighted. This clarified the main purpose of introducing various types of additives into electrolytes to enhance the transport properties as well as the performance of the DSSCs.
