Solid-state dye-sensitized photovoltaic cells have been fabricated with TiO2 as the electron conductor and CuSCN as the hole conductor. These cells involve the nanoscale mixing of crystalline n-type and p-type semiconductors in films that are more than 100 times thicker than the individual n- and p-type domains. Charge transport and field distribution in this kind of material are as yet unexplored. We have used photocurrent and photovoltage transients, combined with variation in the layer thickness, to examine the limiting factors in charge transport and recombination. Charge transport (t 1/2 a¿¿ 200 I¼s) is found to be similar to that in dye-sensitized electrolyte cells. Recombination at Voc (t1/2 a¿¿ 150 I¼s) is 10 times faster than in electrolyte cells, and recombination at short circuit (t1/2 a¿¿ 450 I¼s) is 100 times faster. In the solid-state cells, the similarity of the charge transport and recombination rates results in a low fill factor, and photocurrent losses, both important limiting factors of the efficiency. A simple model is given, and suggestions are made for improvements in efficiency.

Reference of 13395-16-9, Chemistry is a science major with cience and engineering. The main research on the structure and performance of functional materials.Mentioned the application of 13395-16-9, Name is Bis(acetylacetone)copper.

The kinetics and mechanism of copper film growth from the reactions of bis(acetylacetonato)copper(II), bis(hexafluoroacetylacetonato)copper(II), and (vinyltrimethylsilane)(hexafluoroacetylacetonato)copper(I) (Cu(hfac)(vtms)) with copper single crystal surfaces were investigated. Experiments were performed using vibrational spectroscopy (reflection infrared and high-resolution electron energy loss spectroscopies) as well as mass spectrometry (temperature-programmed desorption and integrated desorption mass spectrometries). Both ligand desorption and dissociation were observed upon pyrolysis of these molecules under ultra-high-vacuum conditions. We demonstrate that adsorbed beta-diketonate ligands decompose in a stepwise fashion at temperatures above ?375 K to yield adsorbed CF3 and ketenylidene (?C-C?O) intermediates. These further decompose above ?500 K to leave surface carbon, a major contaminant in copper films grown from CuII beta-diketonates. Clean films can be grown from the pyrolysis of Cu(hfac)(vtms) at pressures above 10-5 Torr, however. The implications of our results relative to the mechanism of copper film growth at elevated pressures are also discussed.

The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 1111-67-7, Name is Cuprous thiocyanate, belongs to copper-catalyst compound, is a common compound. COA of Formula: CCuNSIn an article, once mentioned the new application about 1111-67-7.

Solution-processed CuSCN serving as hole transport, electron reflecting layer (HTL, ERL) and Cu dopant source for CdSe/CdTe thin-film solar has demonstrated high power conversion efficiency (PCE) of ~17%. Two types of solvent, diethyl sulfide (DES) and aqueous ammonia (NH4OH), are explored to deposit CuSCN on CdTe, and both can enhance the performance of CdSe/CdTe solar cells. However, NH4OH solvent is less toxicity, leading to a smoother surface than DES solvent, enabling the deposition of ultra-thin CuSCN layer and avoiding the high cost of DES. Temperature-dependent current-voltage (J-V-T) and capacitance-voltage (C-V-T) measurements reveal that the use of CuSCN HTL increases hole concentration in CdTe absorber and significantly reduces back-contact barrier height. High power conversion efficiency is achievable with the optimal thickness of the CuSCN layer. Our results demonstrate solution-processed CuSCN HTL for enhancing the efficiency and reducing the cost of CdTe thin-film solar cells.

Copper(I) complexes of 1,2-bis(diphenylphosphino)ethane (dppe) with a stoichiometry Cu2(dppe)3(X)2 [X – = CN- (1), SCN- (2), NO3- (3)] are obtained from direct reactions of CuX and dppe. The complexes are structurally and spectroscopically (NMR and IR) characterized. The structure of the [Cu2(dppe)3]2+ dication is similar to the structural motif observed in many other complexes with a chelating dppe and a bridging dppe connecting two copper centers. In complexes 1-3, the anions are confined to the cavity formed by the phosphines which force a monodentate coordination mode despite the predominant bidentate/bridging character of the anions. The coordination angles rather than the thermochemical radii dictate the steric requirement of anions. While the solution behavior of 3, with nitrate, is similar to complexes studied earlier, complexes with pseudohalides exhibit new solution behavior.

Line-imaging Raman spectroscopy provides a contiguous series of Raman spectra along a line in space. The resulting image provides a one-dimensional spatial profile containing information about the bonding and chemical environment being sampled. The instrument configuration described here has a spatial resolution of about 5 mum and a spectral resolution of approximately 10 cm-1. Two examples highlight the use of in situ line-imaging Raman spectroscopy in electrochemical engineering. In the first example, the cation transport and redox characteristics of a thin (? 36 nm) nickel hexacyanoferrate film are probed. The oxidation state of iron centers within the nickel hexacyanoferrate thin film is shown to be readily modulated between ferric and ferrous states in the freshly prepared film. However, repeated cycling results in an irreversible loss of capacity as the iron centers no longer are able to efficiently switch into the ferric state. In the second example, we demonstrate the simultaneous imaging of a thin film of semiconducting copper (I) thiocyanate and the electrolyte chemistry from which the film was deposited. We show that copper thiocyanate electrodeposits have the beta crystal form and the deposition involves a CuSCN+ precursor that forms via homogeneous solution phase chemistry upon addition of copper sulfate to a potassium thiocyanate containing electrolyte.

Treatment of [Et4N][Tp*WS3] (Tp* = hydridotris(3,5-dimethylpyrazol-1-yl)borate) (1) with CuX (X = Br, SCN) and PPh3 or 1,1-bis(diphenylphosphino)methane (dppm) produced two neutral trinuclear clusters [Tp*W(mu3-S)(mu-S)2Cu 2Br(PPh3)] (2) and [Tp*W(mu3-S)(mu-S) 2Cu2(SCN)(dppm)]2·MeCN·Et 2O (3·MeCN·Et2O). Reactions of 1 with [Cu(MeCN)4]PF6, NH4PF6 and 1,3-bis(diphenylphosphino)propane (dppp), N,N-bi(diphenylphosphanylmethyl)-2- aminopyridine (bdppmapy), N,N,N?,N?-tetra(diphenylphosphanylmethyl) ethylenediamine (dppeda), or 1,4-N,N,N?,N?- tetra(diphenylphosphanylmethyl)benzenediamine (dpppda) afforded four clusters containing butterfly-shaped [Tp*WS3Cu2] cores, [Tp*W(mu3-S)(mu-S)2Cu2(dpppds)] (PF6)·1.25MeCN (dpppds = 1,3-bis(diphenylphosphino)propane disulfide) (4·1.25MeCN), [Tp*W(mu3-S)(mu-S) 2Cu2(bdppmapy)](PF6)·3MeCN (5·3MeCN) and {[Tp*W(mu3-S)(mu-S)2Cu 2]2(L)]}(PF6)2·Sol (6·Et2O: L = dppeda, Sol = Et2O; 7·1.25MeCN: L = dpppda, Sol = 1.25MeCN). Compounds 2-7 were characterized by elemental analysis, IR, UV-Vis, 1H and 31P{1H} NMR spectra, electrospray ion mass spectra (ESI-MS) and single-crystal X-ray diffraction. Compound 2 or 3 has a butterfly-shaped [Tp*WS 3Cu2] core in which one [Tp*WS3] unit binds two Cu(i) centers via one mu3-S and two mu-S atoms. In the cationic structure of 4 or 5, one in situ-formed dpppds or bdppmapy combines with the [Tp*WS3Cu2] core via each of its two S atoms or two P atoms coordinated at each Cu(i) center. In the bicationic structure of 6 or 7, two [Tp*WS3Cu2] cores are linked by one dppeda or dpppda bridge to form a bicyclic structure. The isolation of 2-7 with unstable [Tp*WS3Cu2] cores may be ascribed to the coordination of P- or S-donor ligands at Cu(i) centers of these cores. The third-order nonlinear optical (NLO) properties of 2-7 in DMF were also investigated by using the femtosecond degenerate four-wave mixing (DFWM) technique at 800 nm.
