A method for direct inkjet printing of silver nanowire (Ag NW) to form transparent conductive network as the top electrode inverted semi-transparent organic photovoltaic devices (OPV) was developed. The highest power conversion efficiency poly(3-hexylthiophene):phenyl-C61–butyric acid methyl ester (P3HT:PC61BM) based OPV achieved be 2.71% when formed by 7 times printing. In general, with printed Ag NW had similar open-circuit voltage (VOC, around 0.60 V) but lower fill factor (FF, 0.33–0.54)...

The poly(ethylene oxide) solid polymer electrolyte (PEO SPE) has recently received much attention, however, the organic components in SPE are still flammable. In this paper, we find that high efficiency halogen-free aluminum (Al) diethyl hypophosphite flame retardant (ADP) is effective reducing flammability of PEO SPE. SEI layer containing Al and phosphorus (P) inhibits growth lithium dendrite enhances cycle life battery. capacity a LiFePO4/SPE/Li battery ADP 123.2 mAh g–1 at 1.0 C Coulombic...

Abstract The energy band alignment in solar cell devices is critically important because it largely governs elementary photovoltaic processes, such as the generation, separation, transport, recombination and collection of charge carriers. Despite expenditure considerable effort, measurement depth profiles across multiple layers has been extremely challenging, especially for operando devices. Here we present direct visualization surface potential profile over cross-sections organic using...

Silver nanogrid based flexible transparent electrode is recognized as the most promising alternative to ITO for organic electronics, owing its low production cost and excellent flexibility. Typically, a highly conductive thin film coating layer, such PEDOT:PSS (HC-PEDOT:PSS) usually deposited onto Ag-grid smooth surface minimize sheet resistance. In this paper, we found that inverted polymer solar cells with structure of Ag-grid/HC-PEDOT:PSS/ZnO/photoactive layer/MoO3/Al generally exhibits...

Abstract Despite the usefulness of quantum dots (QDs) in biomedicine and optoelectronics, their toxicity risks remain a major obstacle for clinical usages. Hence, we studied reproductive CdSe/ZnS QDs on two aspects, (i) vivo ovarian functions (ii) vitro fertilization process. The body weight, estrous cycles, biodistribution QDs, oocyte maturation are evaluated female mice treated with QDs. mRNA level follicle-stimulating hormone receptor (FSHr) luteinizing (LHr) ovaries assayed. Then,...

Molybdenum disulfide, a type of two-dimensional layered material with unique properties, has been widely used in many fields. However, an exact understanding its toxicity remains elusive, let alone effects on the environmental microbial community. In this study, we utilized metabolomics technology to explore different concentrations molybdenum disulfide nanosheets Escherichia coli for first time. The results showed that increasing concentration nanosheets, survival rate was decreased and...

Understanding the thermal degradation mechanism of organic solar cells (OSCs) and developing strategies to enhance their stability are crucial before they can be commercialized. In this paper, we demonstrated that in a structure-inverted ITO/ZnO/PM6/L8-BO/TCTA/MoO3/Ag cell, thin 4,4′,4″-tris(carbazol-9-yl)-triphenylamine (TCTA) film between MoO3 PM6:L8-BO significantly suppress fast short circuit current (JSC) loss slow but continuous open voltage (VOC) fill factor (FF) decay upon 150 °C...

Abstract Carbon fiber reinforced polyimine (CF/PI) composites had promising applications due to their flame retardancy and ease of recyclability. However, the mechanical properties CF/PI are generally insufficient, optimizing interface between carbon (CF) fabrics (PI) matrix could effectively solve this problem. The interfacial bonding CF PI was enhanced by a combination pre‐treatment grafting with silane coupling agent (APTMS). laminates were prepared “pre‐fabrication‐lamination” method...

The relationship between the particle size and porosity of an Fe-based amorphous coating that is fabricated using a high-velocity oxygen fuel (HVOF) process was revealed by both numerical experimental methods. A computational fluid dynamics model implemented in order to understand gas-flow field behaviour in-flight particles with different sizes during HVOF spray process. By analysing velocity temperature, optimal range (20–30 μm) achieve low-porosity coatings predicted. These calculations...
