Summary: The study shows that utilizing a mixture of two organic dyes as co-sensitizers can enhance the photovoltaic performance of dye-sensitized solar cells. The increase in photocurrent, open-circuit voltage, and fill factor is attributed to the enhanced steady state in the dye mixture and the reduction of recombination loss through the co-sensitization system. The co-sensitizing dye system exhibits complementary characteristics, providing broader optical absorption and increasing the photocurrent density and charge transport capability in a wider spectral region.

Summary: The carbon quantum dot (C-dot) acts as a photosensitizer and dye-adsorber. Adding C-dot to TiO2/NiO(10 wt%) nanocomposites significantly enhances the power conversion efficiency (PCE) of dye-photosensitized solar cells (DSSCs) up to 2.88 times. However, in TiO2/CuO/C-dot nanocomposites, the addition of C-dot leads to a decrease in PCE.

Summary: Dye-sensitized solar cells (DSSCs) have attracted significant attention due to their ease of fabrication, low cost, and environmentally friendly nature. Platinum (Pt) is conventionally used as the counter electrode, thanks to its excellent electrocatalytic activity and high electrical conductivity. However, the corrosive and scarce nature of Pt limits its application. As a result, research efforts are focused on exploring alternative counter electrode materials, with MoS2 and its composites being a promising option. Interestingly, MoS2 can also be utilized as the photoanode in DSSCs. Morphology plays a crucial role in device performance, and the electrochemical investigation and stability of the counter electrodes are important considerations.

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.
