“…The growth of dendrons induced an increase of the interlamellar space and a disorganization of lamella packing. The authors highlighted the use of this dendron‐talc in a gel electrolyte for dye‐sensitized cells (Figure ) . Organotalcs play also a promising role as additives in liquid electrolytes due to their great chemical stability, exclusive swelling capacity and ion‐exchange potential.…”

This contribution gives a comprehensive review about the progress in preparation methods, properties and applications of the different synthetic talc types: i) crystalline nanotalc synthesized by hydrothermal treatment; ii) amorphous and/or short-range order nanotalc obtained by precipitation, and iii) organic-inorganic hybrid talc-like structures obtained through a sol-gel process or a chemical grafting. Several advantages of nanotalc such as high chemical purity, high surface area, tunable submicronic size, high thermal stability, and hydrophilic character (leading to be the first fluid mineral) are emphasized. Synthetic nanotalc applications are also considered including its use as nanofiller in composite materials, as absorbers of organic compounds, as anticorrosion coatings and as agents for cosmetic applications. Regarding their high industrial application potential, intensive research has been carried out to better understand their behavior and develop processes to produce them. To facilitate further research and development, scientific and technical challenges are discussed in this Review article.

“…Electrolyte bleaching is a major cause for degradation of dye solar cells, as reported by numerous groups . Moreover, we have identified the major role being the loss of charge carriers in the electrolyte: In our recent studies this effect has been observed both with the UV light, the intensity of which corresponded to the intensity of 1 Sun illumination at UV range, , and with UV light of lower intensity or even when UV filters were applied. ,,− Note that even the best UV filters will leak some UV light. To efficiently compare the different biomaterials, we adopted accelerated tests at very harsh conditions (>1 Sun UV light level without filter).…”

Biobased cryogel membranes were applied as electrolyte holders in dye solar cells (DSC) while facilitating carrier transport during operation. They also improved device performance and stability. For this purpose, cellulose nanofibers (CNF), TEMPO-oxidized CNF (TOCNF), bacterial cellulose (BC), and chitin nanofibers (ChNF) were investigated. The proposed materials and protocols for incorporating the electrolyte, via simple casting, avoided the typical problems associated with injection of the electrolyte through filling holes, a major difficulty especially in manufacturing large area cells. Owing to the fact that cryogel membranes did not require any orifice for injection, they were effective in minimizing leakage and in retaining liquid electrolyte. The results indicated the reduction of performance losses compared to conventional electrolyte filling, likely due to the better spatial distribution of electrolyte. DSCs based on BC cryogels had an initially higher performance and similar stability compared to those of the reference cells. When compared to reference cells, CNF and ChNF cryogels produced higher initial performance, but they underwent a faster degradation. The difference in stability was attributed to the effect of residual components, including lignin in CNF and proteins in ChNF, as demonstrated in bleaching experiments. TOCNF indicated a relatively poor performance, most likely because of residual aldehydes. Overall, we offer a comprehensive evaluation based on current−voltage (IV) profiles under simulated sunlight, incident photon-to-charge carrier efficiency (IPCE), electrochemical impedance spectroscopy (EIS), and color image processing, together with accelerated DSC stability tests, to unveil the effects of new membrane-based assembly. Our results give guidelines for future developments related in particular to the effects of the tested biomaterials on device stability.

“…The optimum solidifying agent should be inexpensive, inert, abundant and non‐toxic, and thus materials such as cellulose and talc are excellent options. Different types of talc have been investigated by Andrade et al and by saturating the talc with iodine both the initial efficiency and long‐term performance could be maintained high (Andrade et al, , ).…”

Flexible dye‐sensitized solar cells are an intriguing photovoltaic technology, especially from the point of view of integration of photovoltaics into everyday objects, owing to these solar cells conforming easily to different nonplanar geometries and low‐intensity lighting conditions. However, the commercialization of these devices has not yet fully taken off due to few persisting gaps in the optimization of employed materials and processes. Herein, we focus on the recent progress on flexible dye sensitized solar cells, and how obstacles to larger‐scale production have been removed. There have been major advancements in diverse roll‐to‐roll compatible preparation methods of various cell layers, as well as in understanding the corrosion of metal electrodes in liquid electrolyte. We also pinpoint the remaining challenges for full commercialization of these technologies, one of which is reaching long‐term stability in which case sealing of the flexible device plays a major role. Furthermore, environmental considerations such as the life cycle assessment and the use of more sustainable materials in solar cell preparation are discussed.
