Fabrication of CH3NH3PbI3 perovskite-based solar cells: Developing various new solvents for CuSCN hole transport material

Copper (I) thiocyanate (CuSCN) is a cost-competitive hole selective contact for the emerging organic-inorganic hybrid perovskite solar cells. However, limitation of solvent is the main issue for getting an optimal thickness for pin-hole free selective contacts. We have developed various solvents such as mixture of propylsulfide with chlorobenzene (1:1), isopropanol with methylammonium iodide (10 mg/ml) and propylsulfide + isopropanol (1:2) + MAI (10 mg/ml) for dissolving CuSCN. It was found that perovskite layer was more stable once CuSCN coating laid on the top surface using the propylsulfide + isopropanol (1:2) + MAI (10 mg/ml) solvent than conventional propylsulfide by doctor blade technique. By employing low temperature solution-process techniques, power conversion achieved over 10% under full sun illumination by the proposed mixed solvent. CuSCN continues to offer promise as a chemically stable and straightforward replacement for the commonly used expensive organic hole conductor (2,2?,7,7?-tetrakis-(N,N-di-p-methoxyphenylamine)9,9?-spirobifluorene (Spiro-OMeTAD)).

Formation of a disorderd hetero-junction by diffusion of CuI from CuSCN into In2S3 layers: A surface photovoltage study

Charge-selective disordered hetero-junctions were formed in evaporated In2S3 layers by diffusing at 200 C CuI from a CuSCN source. The thicknesses of In2S3 layers and diffusion times were varied between 5 and 80 nm and between 2 and 19 min, respectively. In some cases CuSCN layers were etched back with pyridine. Spectral and time-dependent surface photovoltage measurements were carried out in the capacitor arrangement. It was observed that a competing process of charge separation and relaxation was initiated together with the formation of the charge-selective In2S3/In2S3:Cu hetero-junction. Modulated SPV amplitude for different annealing times and thicknesses of the evaporated In2S3 layers. Copyright

Poly[[(pyridazine-kappaN)copper(I)]-mu3-thiocyanato- kappa3 N:S:S]

The crystal structure of the [Cu(NCS)-(C4H4N 2)]n was investigated. Each Cu atom was coordinated by one N atom of one pyridazine ligand and by one N and two S atoms of three symmetry-related thiocyanate anions within a distorted tetrahedron in the above compound. The compound was prepared by the reaction of CuSCN and pyridazine in acetonitrile in a teflon-lined steel autoclave at 373 K. It was observed that only one N atom of the pyridazine ligand was involved in Cu coordination. It was shown that the Cu atoms were connected via the thiocyanate anions, forming layers parallel to the ab plane.

Highly efficient organic solar cells based on a robust room-temperature solution-processed copper iodide hole transporter

Achieving high performance and reliable organic solar cells hinges on the development of stable and energetically suitable hole transporting buffer layers in tune with the electrode and photoactive materials of the solar cell stack. Here we have identified solution-processed copper(I) iodide (CuI) thin films with low-temperature processing conditions as an effective hole-transporting layer (HTL) for a wide range of polymer:fullerene bulk heterojunction (BHJ) systems. The solar cells using CuI HTL show higher power conversion efficiency (PCE) in standard device structure for polymer blends, up to PCE of 8.8%, as compared with poly(3,4-ethylenedioxy-thiophene):poly(styrenesulfonate) (PEDOT:PSS) HTL, for a broad range of polymer:fullerene systems. The CuI layer properties and solar cell device behavior are shown to be remarkably robust and insensitive to a wide range of processing conditions of the HTL, including processing solvent, annealing temperature (room temperature up to 200. C), and film thickness. CuI is also shown to improve the overall lifetime of solar cells in the standard architecture as compared to PEDOT:PSS. We further demonstrate promising solar cell performance when using CuI as top HTL in inverted device architecture. The observation of uncommon properties, such as photoconductivity of CuI and templating effects on the BHJ layer formation, is also discussed. This study points to CuI as being a good candidate to replace PEDOT:PSS in solution-processed solar cells thanks to the facile implementation and demonstrated robustness of CuI thin films.

Corrosion and fouling study of copper-based antifouling coatings on 5083 aluminum alloy

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.

Linear and cyclic tetranuclear copper(I) complexes containing anions of N,N?-bis(pyrimidine-2-yl)formamidine

The reaction of Kpmf (pmf = anion of N,N?-bis(pyrimidyl-2-yl) formamidine, Hpmf) with CuSCN afforded the complexes K[Cu4(pmF) 3(SCN)2], 1, and Cu4(pmf)4, 2. Reaction of 1 with [(n-Bu)4N]PF6 in THF gave the complex [(n-Bu)4N][Cu4(pmf)3(SCN)2], 3. Their structures were characterized by X-ray crystallography. Complexes 1 and 3 are the first linear tetranuclear complexes containing only Cu(I) atoms, while complex 2 is cyclic. The four Cu(I) atoms of complexes 1 and 3 are helically bridged by three tetradentate pmf- ligands. The [Cu 4(pmf)3(SCN)2]- anions of 1 show weak interactions with adjacent [K(THF)5]+ cations through the sulfur atoms, forming infinite chains which are subjected to a series of intermolecular pi-pi interactions. In complex 2, the pmf- ligands are coordinated to the copper atoms in bidentate fashion through the two central amine nitrogen atoms, leaving the pyrimidine nitrogen atoms uncoordinated. Unexpected fluxional behaviors were observed for complexes 1 and 3 in solution. By the DNMR analysis, the free energy of activation (DeltaGc?) for the exchange is 12.8 kcal mol-1 at 278 K (Tc), and the rate constant of exchange (Kc) is 470 s-1 for 1. The DeltaGc? and Kc are 12.6 kcal mol-1 at 273 K and 433 s-1, respectively, for 3. The Royal Society of Chemistry 2005.
