The development of effective and stable hole transporting materials (HTMs) is very important for achieving high-performance planar perovskite solar cells (PSCs). Herein, copper salts (cuprous thiocyanate (CuSCN) or cuprous iodide (CuI)) doped 2,2,7,7-tetrakis(N,N-di-p-methoxyphenylamine)-9,9-spirobifluorene (spiro-OMeTAD) based on a solution processing as the HTM in PSCs is demonstrated. The incorporation of CuSCN (or CuI) realizes a p-type doping with efficient charge transfer complex, which results in improved film conductivity and hole mobility in spiro-OMeTAD:CuSCN (or CuI) composite films. As a result, the PCE is largely improved from 14.82% to 18.02% due to obvious enhancements in the cell parameters of short-circuit current density and fill factor. Besides the HTM role, the composite film can suppress the film aggregation and crystallization of spiro-OMeTAD films with reduced pinholes and voids, which slows down the perovskite decomposition by avoiding the moisture infiltration to some extent. The finding in this work provides a simple method to improve the efficiency and stability of planar perovskite solar cells.

Development of highly active and durable bifunctional electrocatalysts for overall water splitting is vital for the economical production of H2 as an alternative energy source. Herein, we report the synthesis of Cu2-xS@IrSy@IrRu nanoparticles (CIS@IrRu NPs), which show excellent catalytic performances for both the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in an acidic electrolyte. Benefiting from the optimal composition of IrRu and the stable IrSy shell, the cactus-like IrRu NPs show high electrocatalytic activity and stability. The cactus-like IrRu NPs exhibit optimal HER and OER performances and high stability at a ratio of Ir/Ru 1.00:1.07. In overall water splitting, the CIS@Ir48Ru52 NPs achieve a current density of 10 mA cm-2 at a cell voltage of only 1.47 V in 0.1 M HClO4 electrolyte and show negligible degradation after 100 h of continuous operation in the stability test.

Syntheses and infrared spectroscopic studies are reported for two different polymorphs of copper(I) thiocyanate and for adducts of copper(I) thiocyanate with thiourea (‘tu’) and ethylenethiourea (‘etu’ = imidazolidine-2-thione; (CH2NH)2CS)). These include the previously reported complex CuSCN/etu (1: 2), which has a trigonal monomeric structure, and CuSCN/etu (1: 1), which has a three-dimensional polymeric structure. A mechanochemical/infrared study of the CuSCN: tu (1: 2) system showed that no 1: 2 complex exists in this case, the product being a mixture of a 1: 3 complex and a novel 1: 0.5 complex. The latter complex was prepared both mechanochemically and from solution, and characterized by infrared and solid-state 65Cu broadline NMR spectroscopy. Diagnostic ligand and metal-ligand bands in the IR and far-IR spectra are assigned for both polymorphs of CuSCN and for all of the complexes studied and are discussed in relation to the structures of the complexes.

Semiconducting copper(I) thiocyanate (CuSCN) is actively studied for electronic and optoelectronic applications. Although various kinds of CuSCN-based transistors are reported, these devices suffer from low charge carrier mobility of about 0.01?0.1 cm2 V?1 s?1. Here, ion gel electrolyte consisting of network polymer and ionic liquid is used as a high capacitance gate insulator to achieve high performance CuSCN-based electrolyte-gated transistors (CuSCN-EGTs) with low operation voltage below 1 V. 30 nm thick CuSCN semiconductor film can be formed by a simple solution process with a low processing temperature (?100 C) that is directly applicable to flexible plastic substrates. By doping copper iodide to the CuSCN semiconductor, device performance including drain current and charge carrier mobility of the CuSCN EGT can be improved significantly. The measured charge carrier mobility of ?0.3 cm2 V?1 s?1 is the highest among the reported CuSCN transistors using various gate insulators. These CuSCN-EGTs also display good operation stability under continuous quasistatic external gate voltage sweeps. Such superior electrical performance and versatile processability of ion gel?gated CuSCN transistors make them suitable for use in complimentary circuits and large-area flexible electronics.

This communication describes the crystal structures of CuI complexes and their topological analysis with an emphasis on the Laplacian of the electron density to investigate the characteristics of halogen bonding. To gain insight into the halogen bonds (XBs), we survey wavefunction and DFT methods. The different XBs, that is, Cl···Cl?, I···I?, Br···N3?, and I···SCN?, in the crystal packing of these compounds are categorized as a combination of a region of charge depletion and a region of charge concentration in the valence-shell charge concentration or hole?lump interactions. The full quantum potential based lump?hole concept is more useful than the sigma-hole concept, in which the electrostatic portion of the potential is merely considered. Such a view of halogen bonding can rationalize the geometry around the XBs. The noncovalent interaction reduced density gradient (NCI-RDG) approach was applied to the real-space visualization and quantitative investigation of the XBs as well.

Potentiostatic and electrochemical impedance spectroscopy (EIS) were used to evaluate cuprous oxide (Cu2O) containing coating systems on the localized corrosion of 5083 marine-grade aluminum in simulated ocean water. Test panels coated with a complete coating system and flawed to simulate a coating defect were also exposed for a 3-month field immersion to evaluate differences between Cu2O and cuprous thiocyanate (CuSCN) pigments on fouling and corrosion behaviour. Optical microscopy, scanning electron microscopy (SEM), and energy dispersive X-ray spectroscopy (EDS) were used to evaluate deposits formed on the surfaces after exposure. Results imply that copper leaching from the Cu2O pigment can deposit on the surface marine-grade aluminum, with or without cathodic protection. Cathodic protection resulted in the formation of protective calcareous deposits at potentials more electronegative than ?1000 mV versus silver-silver chloride (Ag/AgCl). Cuprous oxide was shown to be a more resistant to biofouling than the cuprous thiocyanate, but there was an increased likelihood of coating delamination and localized corrosion with the former antifouling pigment.
