Summary: Perovskite solar cells (PSCs), based on inexpensive organic-inorganic hybrid semiconductors, are regarded as a promising next-generation solar cell technology. Efficient and scalable fabrication methods are crucial for the commercialization of PSCs. While solution-based methods have been widely studied for their simplicity and cost-effectiveness, vacuum-based methods are still necessary for achieving reproducibility and uniformity in large-area production. In this review, the precursor and charge transporting materials, as well as various preparation methods for vacuum-processed PSCs, are introduced to provide insights for the commercialization of PSCs.

Summary: Processing solvent additives, such as aromatic ethers, have been found to improve the performance of polymer solar cells (PSCs) more effectively than traditional halogenated solvents. The selection of green solvent additives, with good solvent properties for PC71BM and nonsolvent properties for PTB7, as well as a boiling point slightly higher than the host solvent, can enhance the device performance of PSCs by promoting the formation of a beneficial phase separation morphology in the blend films. This study's proposed principles for green solvent additives can be utilized to optimize the active layer structure of other PSCs that undergo liquid-liquid phase separation.

Summary: This paper characterises exciton generation in three types of bulk-heterojunction organic solar cells, finding that the optimum thickness of the active layer affects the rate of exciton generation. Simulated results indicate that the inverted non-fullerene BHJ OSC1 shows better short circuit current density, potentially leading to better photovoltaic performance.

Summary: This study investigates the phase evolution of PBDB-T:ITIC and PM6:Y6 systems with DIO/CN additives using position-resolved and time-resolved spectroscopy techniques. It is found that a solvent-free liquid film surface is formed during solvent evaporation, and the Flory-Huggins interaction parameters are calculated. Different phase evolution behaviors are observed for the two systems, and surface phase segregation significantly determines the photovoltaic performance.

Summary: Lead halide perovskite and organic solar cells are seen as promising candidates for clean energy applications, but improvements are needed in the near-infrared photon loss and photovoltage deficit. By integrating low-bandgap organic bulk-heterojunction layers into inverted PSCs, high-performance hybrid solar cells can be constructed. These hybrid solar cells demonstrate excellent power conversion efficiency, extended photoresponse, and superior long-term stability compared to single-component PSCs and OSCs. With the highest efficiency reported for flexible solar cells to date, flexible HSCs can be integrated as a power source for wearable sensors, demonstrating real-time temperature monitoring capabilities.

Summary: By using easily accessible oligothiophene donors and acceptors, all-oligothiophene organic solar cells (AOT-OSCs) with satisfactory power conversion efficiencies (PCEs) of 9.30% were realized. Moreover, the devices based on the Tz6T/A4T-16 binary exhibited an excellent industrial figure of merit (i-FoM) of up to 0.168, suggesting the strong potential of all-oligothiophene combinations in developing low-cost and high-efficiency OSCs.

Summary: Using non-halogenated solvents for the green manufacture of high-efficiency organic solar cells (OSCs) is crucial for their future application. However, the poor film microstructure caused by solubility issues leads to lower power conversion efficiency (PCE) compared to halogenated solvent processed OSCs. This study proposes a halogen-free solvent system that optimizes the film microstructure and achieves high-efficiency OSCs. The solvent system, consisting of carbon disulfide and paraxylene, produces a high-quality active layer with efficient charge generation, transport, and collection, resulting in a comparable PCE to the device prepared from a halogenated solvent. This article presents a new strategy for the green fabrication of high-efficiency OSCs to accelerate their industrialization.

Summary: This study developed sustainable biocomposites using Latxa sheep wool fibers and a soy protein isolate (SPI) matrix, which showed excellent acoustic properties. The SEM and XRD analysis confirmed the porous structure and the interaction between soy protein and keratin in wool fibers. The biocomposites demonstrated a high sound absorption coefficient above 0.9 for frequencies above 1000 Hz, comparable to conventional synthetic materials. These findings suggest that sheep wool/SPI biocomposites have the potential to replace synthetic materials in the building industry, enhancing sustainability.
