Summary: Integrating photovoltaic devices onto carbon-fiber-reinforced polymer substrates can create strong materials that also generate electrical power. The fabrication of triple-cation perovskite n-i-p solar cells onto planarized carbon-fiber-reinforced polymer substrates is demonstrated, with devices having a transparent top ITO contact and a wrinkled SiO2 interlayer to prevent cracking. These devices have a maximum power conversion efficiency of 14.5% and a specific power of 21.4 W g(-1), making them suitable for mobile power applications.

Summary: This study explores the potential of cross-linking technology in organic electronic devices, particularly in organic solar cells. A newly synthesized photoreactive tris-azide cross-linker demonstrated high efficiency and excellent charge extraction properties in a p-doped polymer used as a hole transport layer. However, high doping levels in the interlayer were found to decrease solar cell efficiency due to dopant diffusion into the active layer. Care must be taken in future cross-linker material development to immobilize both the host and dopants effectively.

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: Our oceans are vast and difficult to monitor, but a fully autonomous 'Internet of Underwater Things' powered by underwater solar energy could revolutionize data collection. However, traditional silicon solar cells do not perform well underwater, so alternative materials like GaInP variants, CdTe, organic semiconductors, and perovskite semiconductors need to be explored. Challenges such as antifouling coatings and new certification standards must also be addressed.

Summary: In this paper, it is demonstrated that the burn-in degradation in n-i-p type perovskite solar cells (PSCs) is directly related to the migration of Li+ ions from the SnO2 electron transporting layer. To prevent ion movement, a thin cross-linked [6,6]-phenyl-C61-butyric acid methyl ester layer is introduced, resulting in the elimination of burn-in degradation and an increase in device power conversion efficiency.

Summary: Currently, the use of tin oxide and Spiro-OMeTAD as electron transport and hole transport materials, respectively, in perovskite solar cells (PSCs) hinders the performance and stability of the devices due to charge recombination and ion migration. This study introduces a molecule bridging layer of 3,5-bis(fluorosulfonyl)benzoic acid (FBA) onto the SnO2 surface, which effectively improves the energy level alignment and immobilizes Li+ ions in the electron transport layer (ETL), resulting in enhanced power conversion efficiency (PCE) of 24.26% without hysteresis. Additionally, the PSCs with the FBA passivation layer exhibit excellent moisture and operational stability, retaining over 80% of the initial PCE after 1000 hours of aging.

Summary: Improving the thermal stability of polymer solar cells (PSC) is crucial for their industrialization. This paper systematically investigates the effect of high-temperature thermal annealing on the device performance of state-of-the-art polymer:non-fullerene (PM6:Y6) solar cells with an inverted structure. The results reveal that the overall performance decay is mainly attributed to the decrease in open-circuit voltage and fill factor, while the short circuit current remains relatively stable. Pre-annealing on specific films results in different performance decays, indicating that the degradation at the interface is the main reason for the overall performance decay. Further analysis confirms the increased interfacial charge recombination after thermal annealing.

Summary: This study aims to investigate the long-term stability of a poly-3-hexylthiophene (P3HT) organic water-gated thin-film transistor (WG-TFT) operated intermittently over 5750 measurement cycles. Short-term performance changes are mainly attributed to work function changes on the gate electrode, while long-term performance changes are consistent with an increase in the semiconductor trap density. The shift in threshold voltage and decrease in mobility are linearly related to the measurement cycles and caused by electrical stress, while the time immersed in water has little effect on the device.

Summary: This work demonstrates how to obtain reliable data from frequency-dependent continuous-wave modulation spectroscopy. The example of continuous-wave photoinduced absorption (cwPA) is used to illustrate the technique's usefulness in studying long-lived photoexcitations in thin-film solar cell materials. The paper identifies and corrects experimental errors arising at moderate frequencies in modulation spectroscopy and addresses limitations caused by detectors and electronics. The outlined methods serve as a guide to avoid pitfalls and correct for limitations in modulation spectroscopy measurements.

Summary: This study utilizes F4-TCNQ as a dopant to improve the long-term stability of perovskite solar cells. The results demonstrate that F4-TCNQ doping not only renders the perovskite layer hydrophobic, but also enhances the uniformity of dopants in the spiro-OMeTAD layer, reducing aggregation and migration. This work provides a new approach for doping engineering in perovskite solar cells to achieve competitive stability.

Summary: Thin film polyethylene oxide, produced by the thermal evaporation technique, exhibits structural and property differences compared to bulk polyethylene oxide. The dielectric constant of polyethylene oxide thin film is 10 times greater than that of bulk polyethylene oxide. There is consistency among dielectric constants, activation energies, and free volume fractions for both thin film and bulk samples. Polyethylene oxide thin film is observed to be more brittle than bulk polyethylene oxide.

Summary: Although molecular dynamics (MD) simulation is a powerful tool for investigating the atomic-scale structures of complex materials, its reliable and accurate application to multi-component glass systems faces challenges due to limited force fields (FFs) and the complexity of chemical environments. This study demonstrates the feasibility of efficient and accurate large-scale density functional theory (DFT) calculations for multi-component glass systems. The evaluation of classical FFs based on the results of large-scale DFT calculations reveals low accuracy for non-bridging oxygen atoms, and differences in Si-O-Si angle distribution and electronic structure for X = Mg.

Summary: In this study, vanadium oxide xerogel samples were successfully synthesized through a liquid phase reaction and the interaction of films with water. The samples were thoroughly analyzed using X-ray diffraction and Raman spectroscopy, revealing the existence of two distinct phases. It was also discovered that previous misinterpretations regarding the high-pressure polymorph structure were due to the formation of a high-temperature phase. These findings highlight the potential for further refining and expanding the current structural models of vanadium oxide xerogel in future research efforts.
