Summary: In order to improve the efficacy of organic solar cells, six new three-dimensional small donor molecules (IT-SM1 to IT-SM6) were computationally designed by modifying the peripheral acceptors of the reference molecule (IT-SMR). These modified molecules exhibited a smaller band gap, lower excitation energies, and a redshift in their absorption maxima compared to IT-SMR. They also showed improved electron and hole mobility, as well as higher open-circuit voltage and fill factor values, making them promising candidates for future use in organic solar cell manufacturing.

Summary: Subtle modification of the electron-withdrawing end group of small-molecule acceptors (SMAs) plays a crucial role in regulating their structure, optoelectronic properties, and device performance. In this study, we developed two SMAs based on indacenodithieno[3,2-b]thiophene by employing hybrid dihalogenated 1,1-dicyanomethylene-3-indanone as end groups. The effects of hybrid dihalogenated end groups on solubility, photoelectrochemical properties, morphology, and device performance were comprehensively investigated. The results showed that hybrid dihalogenation improved the absorption ability and elevated the lowest unoccupied molecular orbitals of the corresponding SMAs, leading to increased short-circuit current density and open-circuit voltage. Furthermore, the solubility of the SMAs in nonhalogenated solvents was improved, enabling the fabrication of devices with environmentally friendly solvents. Polymer solar cells based on these SMAs demonstrated enhanced power conversion efficiency compared to their counterparts, highlighting the feasibility of using hybrid dihalogenation to improve the performance of PSCs fabricated with eco-friendly solvents and additives.

Summary: This work focused on the design and synthesis of three IDTT dimers for use in PSCs, exploring the impact of core effects on their performance. It was found that introducing electron-donating linkages raised energy levels of the dimers, leading to increased open-circuit voltages. Thienothiophene was identified as a more suitable linkage unit compared to dithiophene, with the highest power conversion efficiency recorded in devices based on dimer dIDTT.

Summary: The direct arylation of different side chain functional groups on 2,7-dibromofluorene was investigated, and the resulting TFB-substituted fluorene derivatives were used to synthesize water/alcohol soluble conjugated polymers. Monomers carrying phosphonate and amino groups could be successfully polymerized under typical DArP conditions, while monomers with bromohexyl side chains required different conditions for preparation. High performance organic solar cells were fabricated using the polymers made through DArP as cathode interfacial layers.

Summary: This study systematically investigated the optical and electrochemical properties, charge mobility, dielectric constants, and photovoltaic performance of three non-fullerene acceptors (NFAs). It was found that the NFA ITOR-IC4F, with 2-3-(oxo-5,6-difluoro-indane-1-ylidene)-malononitrile end groups, exhibited the narrowest bandgap and highest dielectric constant. Moreover, polymer solar cells (PSCs) based on PM6:ITOR-IC4F showed the highest efficiency. The results suggest that introducing fluorine atoms into the end groups is more beneficial for improving the dielectric constant and performance of NFAs.

Summary: This study investigates the effect of minor modifications to side-chain density on polaron formation in organic semiconductors and demonstrates their impact on the electrical response of polymers in gas sensing. The results show that reducing side-chain density leads to a multistep polaron formation and allows for the formation of a higher density of polarons with fewer structural changes. More numerous but more localized polarons generate a stronger analyte response but lack selectivity between polar and non-polar solvents, while more delocalized polarons show clear selectivity.

Summary: Flexible iron-doped SrTiO3 (SFTO) nanofibrous membranes were prepared through electrospinning and calcination. These membranes can be easily isolated and recycled as photocatalysts. The SFTO nanofibrous membranes exhibited enhanced photocatalytic performance under strong acids and strong alkalis, increasing the catalytic rate of Congo red (CR) dye by about 10 times in visible light. The mechanism of photocatalytic activity enhancement was attributed to the combined effects of hydroxyl radicals and superoxide radicals. The successful preparation of SFTO nanofibrous membranes provides a simple and economical approach for photocatalysis and environmental remediation.

Summary: In this study, the impact of different concentrations of ginsenosides on soil chemical and microbial properties was investigated. The results showed that ginsenosides significantly altered soil enzyme activities and reduced the physicochemical properties dominated by soil organic matter, thereby changing the composition and structure of the soil microbial community. Particularly, the application of 10 mg/L ginsenosides increased the relative abundance of pathogenic fungi. These findings suggest that ginsenosides in root exudates are important factors leading to increased soil deterioration during ginseng cultivation and provide a new research direction for studying the interaction mechanism between ginsenosides and soil microbial communities.

Summary: In this study, the influence of molecular packing and orientation of conjugated polymer chains in thin films on the charge transport properties and device performance of polymer-based optoelectronic devices was extensively investigated. The effects of various processing conditions on the thin-film microstructure were studied using grazing-incidence wide-angle X-ray scattering. It was found that the recently discovered third crystalline form of a well-studied electron transporting polymer evolved directly from the face-on oriented form upon melting under specific conditions.

Summary: The energy levels between PTB7-Th/ITIC and ZnO in a photovoltaic device are well aligned, and a double dipole is formed between PTB7-Th/ZnO. ZnO is commonly used as a cathode interface layer due to its ability to extract electrons from the active layer. This study focuses on the electronic structure of the interface between ZnO and an active layer containing PTB7-Th and ITIC. Various electron spectroscopy techniques were used to determine the energy levels of these materials at their interface. The findings show that PTB7-Th and ITIC are well aligned with ZnO, and two dipoles are formed at the PTB7-Th/ZnO interface.

Summary: In all-polymer solar cells, the fine-grained morphology of the film in the active layer contributes to high performance, but the mechanism behind it is still unknown. Polymeric non-fullerene acceptors have the potential to limit self-aggregation, unlike non-fullerene small molecule acceptors. This study investigates the balance between molecular interactions in a blend of the polymeric acceptor PF5-Y5 and the donor polymer PBDB-T. The results provide insights into the formation of donor-acceptor charge transfer complexes and their competition with donor and acceptor self-aggregation, which can have significant impacts on the film morphology of all-polymer blends.

Summary: In this study, the effect of embedding colloidal gold nanoparticles (cAu NPs) in the ZnO electron transport layer (ETL) on the power conversion efficiency (PCE) of wide band gap polymer-based inverted organic solar cells (OSCs) was investigated. The PCE of the reference device was improved by 22% when 10 wt% cAu NPs were embedded in the ZnO ETL. The enhancement in PCE was mainly attributed to the improved absorption in the active layer due to the localized surface plasmon resonance (LSPR) of cAu NPs, as well as the efficient exciton dissociation and charge collection.
