Summary: The study found that 1,3-dialkyltriazolium iodides exhibit high chemical and thermal stability, with significant changes in electrolyte properties upon addition of different iodine content, where iodine addition usually leads to a decrease in melting point and an increase in conductivity. Compared to imidazolium iodides, triazolium compounds show higher efficiency and longer battery life, possibly due to their non-hygroscopic nature.

Summary: Dye-sensitized solar cells (DSSCs) are a promising solution for portable electronics and IoT applications due to their low-cost fabrication and high efficiency. However, the main obstacle to their large-scale exploitation is their limited long-term stability caused by liquid electrolytes. This review summarizes advances in alternative polymer electrolytes, with a focus on polysiloxane-based poly(ionic liquid)s, and evaluates their behavior in DSSCs. The assessment of printability for liquid and gel polymer electrolytes, particularly polysiloxane-based electrolytes, is also discussed.

Summary: This mini review briefly discusses the developments on the application of polypyridyl-based copper complexes in dye-sensitized solar cells (DSSCs). Copper complexes can be used as dye sensitizers and/or as redox mediators in DSSCs. The abundance and low cost of copper make it a cheaper and non-toxic alternative to the commonly used iodide/triiodide electrolyte redox couple and the expensive and rare ruthenium-based dyes.

Summary: Different redox shuttle-mediated polymer gel electrolytes were used to fabricate quasi-solid-state dye-sensitized solar cells for outdoor and indoor applications. The power conversion efficiency of these cells was comparable to liquid electrolyte-devices under various illuminations. The efficiency of cobalt and copper complex-mediated gel electrolytes was particularly high under compact fluorescent light illumination.

Summary: Redox mediators are crucial in dye-sensitized solar cells, and copper complexes are a good option, despite electron recombination issues. By synthesizing two helical copper(I) complexes and eliminating the use of 4-(tert-butyl)pyridine, the efficiency of the solar cells was improved. Increasing the concentration of (CuLa)-La-I showed an increase in both photocurrent and photovoltage, leading to the best power conversion efficiency at 8.2%. Further investigation into the relationship between Cu(I) concentration and recombination was conducted for future research.

Summary: In this study, hydroxypropyl cellulose (HPC)-based gel polymer electrolytes with different alkali metal iodide salts were investigated. The addition of potassium iodide (KI) salt resulted in the highest ionic conductivity, followed by sodium iodide (NaI) and lithium iodide (LiI). Furthermore, the incorporation of sonochemically synthesized cobalt oxide (Co3O4) nanoparticles into the KI sample further improved the ionic conductivity, reduced the activation energy and degree of crystallinity of the electrolyte. Dye sensitized solar cells assembled with the developed gel polymer electrolytes showed improved short-circuit current density and efficiency. The electrolyte containing 7 wt% of Co3O4 nanoparticles achieved the best ionic conductivity and photovoltaic performance.

Summary: The design of a solid electrolyte interphase (SEI) plays a crucial role in improving the electrochemical performance of anode materials. In this study, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to form a protective SEI film on Li3VO4 (LVO) anodes. The addition of LiDFOB results in a dense, uniform, stable, and LiF-richer SEI, which enhances the Li-ion storage kinetics. The generated SEI also prevents further decomposition of the electrolyte and maintains the morphology of LVO anodes during charge/discharge processes. This work demonstrates the effectiveness of LiDFOB as a multi-functional additive for LiPF6 electrolytes and provides insights into SEI construction for high-performance LVO anodes.

Summary: In this study, we used density functional theory (DFT) calculations to investigate the interaction between model graphene oxide (GO) nanostructures and chlorine monoxide ClO. We aimed to understand the role of this highly oxidizing species in breaking C-C bonds and forming significant holes on GO sheets. Our results showed that C-C bonds in a single graphene oxide sheet can be broken through a simple mechanism involving the dissociation of two chemically attached ClO molecules. The formation of carbonyl groups and holes on the GO surface was also observed. This study provides important insights into the degradation of carbon nanotubes and the stability of GO during the myeloperoxidase (MPO) catalytic cycle.

Summary: In this study, the X-ray stability of five different lead halide perovskite compositions (MAPbI3, MAPbCl3, MAPbBr3, FAPbBr3, CsPbBr3) was investigated using photoelectron spectroscopy. Different degradation mechanisms and resistance to X-ray were observed depending on the crystal composition. Overall, perovskite compositions based on the MA+ cation were found to be less stable than those based on FA+ or Cs+. Metallic lead formation was most easily observed in the chloride perovskite, followed by bromide, and very little in MAPbI3. Multiple degradation processes were identified for the bromide compositions, including ion migration, formation of volatile and solid products, as well as metallic lead. CsBr was formed as a solid degradation product on the surface of CsPbBr3.

Increasing the manganese content leads to a decrease in stability. The behavior of iron and manganese in the oxide shows distinct differences, which can be attributed to the difference in the enthalpy of oxidation reactions. Additionally, the change in the La/Sr ratio affects the concentration of iron and manganese ions.
