A solar cell sensitized with three different dyes

Construction of a semiconductor – dye heterostructure of the configuration n-TiO2/D1/p-CuSCN/D2/p-CuSCN/D 3/p-CuSCN. (n-TiO2 is the nanocrystalline TiO2 film deposited on conducting glass, p-CuSCN = ultra-thin (?2 nm) layers of Cu(I) thiocyanate, p-CuSCN = thick layer of p-CuSCN, D 1 = Fast Green, D2 = Rhodamine 6G and D3 = Acridine Yellow) is described. It is found that this heterojunction generates photovoltaic response to light absorption by all the three dyes. The mechanism involved is suggested to be transfer of electrons to n-TiO2 and holes to p-CuSCN via tunneling. This technique could be a strategy to broaden the spectral response and enhance the efficiency of dye-sensitized solar cells.

Stepwise addition of CuNCS onto [Et4N][Tp*WS3]: Design, syntheses, structures and third-order nonlinear optical properties

Stepwise reactions of [Et4N][Tp*WS3] (1) (Tp* = hydridotris(3,5-dimethylpyrazol-1-yl)borate) with 1-4 equiv. of CuNCS (and Et4NBr in the case of three equiv. of CuNCS) afforded the [1 + 1] to [1 + 4] addition products [Et4N][Tp*WS(mu-S) 2(CuNCS)]·0.5CH2Cl2 (2·0.5CH 2Cl2), [Et4N][Tp*W(mu3-S) (mu-S)2(CuNCS)2]·ClCH2CH 2Cl (3·ClCH2CH2Cl), [Et 4N]2[Tp*W(mu3-S)3(CuNCS) 3(mu3-Br)]·1.5aniline (4·1.5aniline), and {[Et4N][Tp*W(mu3-S)3(Cu-mu-SCN) 3(Cu-mu3-NCS)]}n (5). Compounds 2-5 were characterized by elemental analysis, IR spectra, UV-vis spectra, 1H NMR, and single-crystal X-ray crystallography. The cluster anion of 2 contains a [WS2Cu] core formed by addition of one CuNCS group onto the [Tp*WS3] species. The cluster anion of 3 has a butterfly-shaped [WS3Cu2] core constructed by addition of two CuNCS groups onto the [Tp*WS3] species. The cluster dianion of 4 consists of a cubane-like [Tp*WS3Cu3(mu3-Br)] core assembled by addition of three CuNCS groups onto the [Tp*WS 3] species followed by filling a mu3-Br into the void of the incomplete cubane-like [Tp*WS3(CuNCS)3] fragment. 5 has a 2D cluster-supported layer network in which each [Tp*WS3Cu3] core acting as a pyramidal 3-connecting node interconnects with the [Cu(NCS)4] units through thiocyanate bridges. In addition, the third-order nonlinear optical (NLO) performances of 2-5 in DMF were also investigated by Z-scan techniques.

Solution-based synthesis and characterization of Cu2ZnSnS 4 nanocrystals

(Figure Presented) Recent advances have been made in thin-film solar cells using CdTe and CuIn1-xGaxSe2 (CIGS) nanoparticles, which have achieved impressive efficiencies. Despite these efficiencies, CdTe and CIGS are not amenable to large-scale production because of the cost and scarcity of Te, In, and Ga. Cu2ZnSnS4 (CZTS), however, is an emerging solar cell material that contains only earth-abundant elements and has a near-optimal direct band gap of 1.45-1.65 eV and a large absorption coefficient. Here we report the direct synthesis of CZTS nanocrystals using the hotinjection method. In-depth characterization indicated that pure stoichiometric CZTS nanocrystals with an average particle size of 12.8 ± 1.8 nm were formed. Optical measurements showed a band gap of 1.5 eV, which is optimal for a single-junction solar device.

Metal exchange in lithiocuprates: Implications for our understanding of structure and reactivity

New reagents have been sought for directed ortho cupration in which the use of cyanide reagents is eliminated. CuOCN reacts with excess TMPLi (TMP = 2,2,6,6-tetramethylpiperidide) in the presence of limited donor solvent to give crystals that are best represented as (TMP)2Cu0.1Li0.9(OCN)Li2(THF) 8, whereby both Lipshutz-type lithiocuprate (TMP)2Cu(OCN)Li2(THF) 8a and trinuclear (TMP)2(OCN)Li3(THF) 8b are expressed. Treatment of a hydrocarbon solution of TMP2CuLi 9a with LiOCN and THF gives pure 8a. Meanwhile, formation of 8b is systematized by reacting (TMPH2)OCN 10 with TMPH and nBuLi to give (TMP)2(OCN)Li3(THF)211. Important to the attribution of lower/higher order bonding in lithiocuprate chemistry is the observation that in crystalline 8, amide-bridging Cu and Li demonstrate clear preferences for di- and tricoordination, respectively. A large excess of Lewis base gives an 8-membered metallacycle that retains metal disorder and analyses as (TMP)2Cu1.35Li0.659 in the solid state. NMR spectroscopy identifies 9 as a mixture of (TMP)2CuLi 9a and other copper-rich species. Crystals from which the structure of 8 was obtained dissolve to yield evidence for 8b coexisting in solution with in situ-generated 9a, 11 and a kinetic variant on 9a (i-9a), that is best viewed as an agglomerate of TMPLi and TMPCu. Moving to the use of DALi (DA = diisopropylamide), (DA)2Cu0.09Li0.91(Br)Li2(TMEDA)212 (TMEDA = N,N,N?,N?-tetremethylethylenediamine) is isolated, wherein (DA)2Cu(Br)Li2(TMEDA)212a exhibits lower-order Cu coordination. The preparation of (DA)2Li(Br)Li2(TMEDA)212b was systematized using (DAH2)Br, DAH and nBuLi. Lastly, metal disorder is avoided in the 2:1 lithium amide:Lipshutz-type monomer adduct (DA)4Cu(OCN)Li4(TMEDA)213.

A new complex salt [4,7,13,16,21,24-hexaoxa-1,10-diazoniabicyclo[8.8.8] hexacosane bis[dichloro(thiocyanato)copper(II)], [H2(Crypt-222)] [CuCl2(SCN)]2, is synthesized and studied by X-ray diffraction analysis. The crystals are monoclinic (space group C2/c, a = 14.603 A, b = 8.330 A, c = 25.091 A, beta = 100.76, Z = 4). The structure is solved by a direct method and refined by the full-matrix least-squares method in the anisotropic approximation to R = 0.047 for 2943 independent reflections (CAD-4 automated diffractometer, lambdaMoK alpha radiation). The Cu2+ cations and Cl- and SCN- anions form infinite polymeric chains of spiro-conjugated alternating centrosymmetric four-membered CuCl2Cu cycles and eight-membered Cu(SCN)2Cu cycles through coordination bonds. The coordination polyhedron of the Cu2+ cation is a distorted trigonal bipyramid. The [H2(Crypt-222)]2+ dication contains trifurcate N+-(…O)3 bonds on axis 2. Nauka/Interperiodica 2007.

Indirect determination of cefradine with n-propyl alcohol-ammonium sulfate-water system by extraction-flotation of cuprous thiocyanate

A new method was developed for the determination of cefradine by extraction-flotation of CuSCN. The experiment indicated that in the presence of 0.20 mol/L NaOH the degradation of cefradine took place in water bath at 100 C. The thiol group (-SH) of the degradation product could reduce Cu(II) to Cu(I) for the formation of the emulsion CuSCN in the presence of NH4SCN at pH 4.0. By determining the residual amount of Cu(II) in the solution and calculating the flotation yield of Cu(II), the indirect determination of cefradine can be obtained. This method has been applied to determine cefradine in capsules, human serum and urine samples, respectively.

A mild copper-catalyzed aerobic oxidative thiocyanation of arylboronic acids with TMSNCS

A facile and efficient transformation of arylboronic acids to their corresponding aryl thiocyanates has been successfully developed. Based on the CuCl-catalyzed oxidative cross-coupling reaction between arylboronic acids and trimethylsilylisothiocyanate (TMSNCS) under oxygen atmosphere, the transformation can be readily conducted at ambient temperature. The newly-developed protocol provided a competitive synthetic approach to aryl thiocyanates that can tolerate a broad range of reactive functional groups and/or strong electron-withdrawing groups.

Electrodeposition of p-type CuSCN thin films by a new aqueous electrolyte with triethanolamine chelation

A stable aqueous electrolyte solution containing Cu2+ and SCN- was prepared by adding triethanolamine (TEA, N(CH 2CH2OH)3) to chelate with Cu(II) cations. The electrolyte solutions were basic, with pH values in the range of 8.5-9, and could be used in the electrodeposition of CuSCN as a hole-conducting layer on a ZnO substrate and as an electron-conducting layer for nanocrystal photovoltaic cells because it could prevent the ZnO layer from acidic etching. CuSCN films were potentiostatically deposited on indium tin oxide glass substrates through the aqueous solutions, and the deposition potential for the sole CuSCN phase layer was determined by a linear sweep voltammetry measurement. The influence of applied potentials, electrolyte components, and deposition temperatures on the stoichiometry, phase, and particle morphology of the CuSCN films was investigated by X-ray photoelectron spectra, X-ray diffraction, and a field-emission scanning electron microscope. The results showed that the morphology of the dense CuSCN films was trigonal pyramid and the stoichiometric portions of SCN/Cu were excess of SCN. The current-voltage (I-V) characteristic of the junction between electrodeposited CuSCN and ZnO nanostructured layer displayed p-type semiconductor characteristics of CuSCN. The transmittance measurements detected high transmittance (?87%) in the visible wavelength range, and the direct transition band gap calculated was 3.88 eV.
