Summary: To improve the stability and efficiency of perovskite-silicon tandem solar cells, reductions in recombination losses are necessary. This was achieved by combining a triple-halide perovskite with a piperazinium iodide interfacial modification, resulting in improved band alignment, reduced nonradiative recombination losses, and enhanced charge extraction. The tandem solar cells achieved high open-circuit voltages and certified power conversion efficiencies of up to 32.5%.

Summary: This study presents a monolithic hybrid tandem solar cell with an all-organic blend as the rear subcell, using metal-ion doped all-inorganic perovskite front subcells and a solution-processed ternary organic blend rear subcell. The use of dynamic hot-air deposition technology allows the fabrication and testing of the solar cells entirely in the open air, and passivation and selection layer treatments improve efficiency and reduce open-circuit voltage loss. The solar cells achieved a maximum efficiency of 23.07% and retained over 90% of the initial efficiency after 600 hours of continuous illumination.

Summary: Solar-to-electrochemical energy storage is an important solar utilization technology, which includes solar cell and photocatalysis cell. While integrated solar batteries achieve indirect solar energy storage, the emerging coupled solar batteries allow direct solar energy storage. However, issues of rapid charge recombination and misaligned band energy have hampered the efficiency and development of coupled solar batteries. This review discusses the design of photoelectrochemical storage materials and coupled solar batteries to promote coupling between photogenerated charges and redox reactions for high efficiency, along with opportunities for new devices with matched band alignments.

Summary: Wide-bandgap perovskite solar cells (PSCs) and narrow-bandgap organic solar cells (OSCs) integrated tandem solar cells (TSCs) have great potential for overcoming the limitations of single junction structures, particularly with the use of orthogonal solvents for each subcell. However, high bromine content in wide-bandgap perovskites leads to phase segregation and voltage loss, while the commonly used interconnection layer (ICL) in TSCs results in significant optical loss. In this study, a simplified SnOX buffer layer is developed as the ICL in perovskite-organic TSCs, which effectively reduces phase segregation and improves light harvesting in the near-infrared region.

Summary: In this study, polymer compounds were produced by melt-compounding carbon black with polycarbonate, with compositions close to or above the electrical percolation threshold. The effects of nanofiller dispersion/aggregation, phase composition, glass transition temperature, morphology, and textural properties were studied using thermal analysis methods and scanning electron microscopy. Additionally, the DC electrical properties of these materials were investigated and correlated with the structure of the carbon black to explain the behavior of the composites near the percolation threshold.

Summary: This study investigates the effect of carbon black dispersion on the mechanical and electrical properties of polyamide 6 and 6.6 matrices. By increasing the carbon black concentration, the elastic modulus increases by 12%. Results show that carbon black can functionalize thermoplastic polymers by activating conductive networks, with a percolation threshold of 13% wt. The sensitivity of conductivity to mechanical strain is analyzed in both direct and alternate current, and a novel model for estimating the material's gauge factor variation with applied electric frequency is proposed.

Summary: In this contribution, MoS2 nanostructures were prepared on the surface of TiO2 nanoparticles through an in situ bottom-up approach, and a multi-technique approach was used to compare the properties of MoS2 slabs on different shaped TiO2 nanoparticles. The results showed that the bottom-up approach allowed for atomic-level growth of MoS2 slabs, leading to effective chemical interactions and enhanced photocatalytic activity. The crystal face heterojunctions between coexposed {101} and {001} facets of anatase TiO2, as well as the semiconductor heterojunctions between MoS2 and TiO2 nanostructures, were considered to play a crucial role in this process.

Summary: It is advantageous to develop an in vitro platform for predicting the complexity of in vivo systems. The initial step involves identifying a xenobiotic that undergoes monooxygenation through two sequential enzymatic reactions. Pesticides, specifically metabolized by human flavin-containing monooxygenase 1 (hFMO1) and cytochrome P450 (CYP), serve as a suitable model for tandem reactions. By immobilizing hFMO1 on glassy carbon electrodes modified with graphene oxide (GO) and cationic surfactant didecyldimethylammonium bromide (DDAB), the feasibility of the in vitro platform is demonstrated. The bioelectrode successfully catalyzes the expected sulfoxide products of three pesticides and exhibits the ability to mimic complex metabolic reactions of xenobiotics within the human body when tested in a tandem system with hFMO1 and CYP3A4.

Summary: Graphitic carbon nitride (g-C3N4) is a promising solar-light-activated photocatalyst due to its thermal stability, environmentally friendly characteristics, and sustainability. However, its photocatalytic performance is limited by low surface area and fast charge recombination. Many efforts have been made to overcome these limitations by improving synthesis methods and proposing different structures. In this study, the nature of polymerised carbon nitride structures obtained from the direct heating of melamine under mild conditions was investigated using various analytical techniques and calculations. The results indicate the presence of highly condensed g-C3N4 domains embedded in a less condensed melon-like framework.
