Perovskites photovoltaic solar cells: An overview of current status

Perovskite based solar cells have recently emerged as one of the possible solutions in the photovoltaic industry for availing cheap solution processable solar cells. Hybrid perovskites display special combination of low bulk-trap densities, ambipolar charge transport properties, good broadband absorption properties and long charge carrier diffusion lengths, which make them suitable for photovoltaic applications. The year 2015 witnessed an upsurge in the published research articles on perovskite solar cells (PSC) which is indicative of the potential of this material. Since the introduction of PSC the power conversion efficiency has reached above 22% in a relatively short period of time. However, the poor reproducibility in device fabrication and lack of uniformity of the PSCs performances is a major challenge in obtaining highly efficient large scale PSC devices. The aim of this paper is to present a brief review on the current status of perovskites based solar cell due to the use of different device architectures, fabrication techniques as well as on the use of various electron and hole interfacial layers (HTMs and ETMs). The review also discusses the basic mechanisms for device operation which provides better understanding on the properties of the various layers of device structures.

Copper-Catalyzed Silylation of C(sp3)-H Bonds Adjacent to Amide Nitrogen Atoms

A copper-catalyzed C-Si bond formation between N-halogenated amides and Si-B reagents is described. This oxidative coupling enables the silylation of C(sp3)-H bonds alpha to an amide nitrogen atom. The utility of the new method is demonstrated for sulfonamides, and N-chlorination with tBuOCl and C-H silylation employing CuSCN/4,4?-dimethoxy-2,2?-bipyridine as catalyst can be performed without purification of the N-Cl intermediate.

Microstructures, optical and photovoltaic properties of CH3NH3PbI3(1-x)Clx perovskite films with CuSCN additive

Microstructures, optical and photovoltaic properties of CH3NH3PbI3(1-x)Clx perovskite films with copper(I) thiocyanate (CuSCN) additive were investigated. The CuSCN-added CH3NH3PbI3(1-x)Clx films were prepared by a hot air blow-assisted spin-coating method. Current density-voltage characteristics of the photovoltaic device using the CuSCN-added CH3NH3PbI3(1-x)Clx light-absorbing layer showed increases in short-circuit current density, open-circuit voltage, which resulted in increase in the conversion efficiency. Microstructure analysis showed that the crystal structure of the CuSCN-added CH3NH3PbI3(1-x)Clx was a pseudocubic system. From these results, partial substitutions of Pb2+ and anions (I- and Cl-) by Cu ions (Cu+ and Cu2+) and SCN-, respectively, are considered to occur in the CuSCN-added CH3NH3PbI3(1-x)Clx films. Based on the obtained results, reaction mechanisms of the CH3NH3PbI3(1-x)Clx films with and without CuSCN additive were discussed.

Bright green-to-yellow emitting Cu(i) complexes based on bis(2-pyridyl)phosphine oxides: Synthesis, structure and effective thermally activated-delayed fluorescence

A family of brightly luminescent dinuclear complexes of [Cu(mu2-X)(N^N)]2 type (X = I or SCN) has been synthesized in 76-90% yields by the reaction of bis(2-pyridyl)phosphine oxides (N^N) with the corresponding Cu(i) salts. The X-ray diffraction study reveals that the Cu2I2 core of the [Cu(mu2-I)(N^N)]2 complexes has either a butterfly- or rhomboid-shaped structure, while the eighth-membered [Cu(SCNNCS)Cu] ring in the [Cu2(SCN)2(N^N)]2 complexes is nearly planar. In the solid state, these compounds exhibit a strong green-to-yellow emission (lambdaemmax = 536-592 nm) with high PLQYs (up to 63%) and short lifetimes (1.9-10.0 mus). The combined photophysical and DFT study indicates that the ambient-temperature emission of the complexes obtained can be assigned to the thermally activated-delayed fluorescence (TADF) from the 1(M + X)LCT excited state, while at 77 K, phosphorescence from the 3(M + X)LCT state is likely observed.

Synthesis and characterization of two types of skeleton heterobimetallic trinuclear Mo(W)-Cu-S clusters containing 1,2-bis(diphenylphosphino)-1,2-dicarba-closo-dodecaborane

Reactions of (NH4)2MS4 or (NH4)MOS3 (M = Mo, W) with CuSCN and the closo carborane diphosphine 1,2-(PPh2)2-1,2-C2B10H10 in CH2Cl2 yielded five heterobimetallic trinuclear Mo(W)-Cu-S clusters with the formula Cu2MS4L2 (M = Mo(1), W(3), L = 1,2-(PPh2)2-1,2-C2B10H10), Cu2MoS4L2 ¡¤ CH2Cl2 (2) and Cu2MOS3L2 (M = Mo(4),W(5)). All the clusters have been characterized by elemental analysis, FT-IR, UV/Visible, 1H and 13C NMR spectroscopy and X-ray structure determination. X-ray crystal structure analysis showed that the metal skeleton of these clusters could be classified into two types. With (NH4)2MS4 (M = Mo, W), the three metal atoms (two Cu atoms and one M atom (M = Mo, W)) are almost in a linear conformation, while with (NH4)2MOS3 the conformation of the heterobimetallic trinuclear cluster core was a butterfly-shaped (or referenced as defective cubane-like with two corners missing). The coordination sphere of the metal atoms in all the clusters, either for Cu or M, should be described as a distorted tetrahedron. For each cluster, the closo carborane diphosphine ligand 1,2-(PPh2)2-1,2-C2B10H10 was introduced into the Cu2MS4 or Cu2MOS3 cluster cores and coordinated bidentately through the P atoms to Cu(I), and this resulted in a stable five-member chelating ring between the bis-diphosphine ligand and the metal.

A single-helix copper-containing coordination polymer of dihydroglyoxaline sulfide formed in situ through oxidation of 1,3-imidazolidine-2-thione

A novel single-stranded helix coordination polymer [Cu(L)(SO4)(H2O)] (L = dihydroglyoxaline sulfide) was synthesized and characterized by single-crystal X-ray diffraction, IR, and TGA analysis. The polymer is an unprecedented 1D helical polymer based on a sulfate bridge and a dihydroglyoxaline sulfide chelating ligand. Both ligands were formed in situ through copper-mediated oxidation of 1,3-imidazolidine-2-thione. The helical chain is interlocked with each other through strong hydrogen bonding interactions to form a 2D sheet, which then stacks together to generate a 3D hydrogen bonding network.

Synthesis, molecular structures and ESI-mass studies of copper(I) complexes with ligands incorporating N, S and P donor atoms

Equimolar reaction of copper(I) bromide with 2-thiouracil (tucH2) in acetonitrile-methanol formed a light yellow solid which on subsequent treatment with a mole of triphenyl phosphine (PPh3) in chloroform has yielded a sulfur-bridged dinuclear complex, [Cu2Br2(mu-S-tucH2)2(PPh3)2] 2CHCl3 1. A reaction of copper(I) bromide with two moles of 2,4-dithiouracil (dtucH2) in acetonitrile-methanol followed by addition of two moles of PPh3, designed to form [Cu(mu-S,S-dtuc)2(PPh3)4Cu] 2a, instead resulted in the formation of previously reported polymer, {CuBr(mu-S,S-dtucH2)(PPh3)}n 2. Reaction of copper(I) iodide with 2-thiouracil (tucH2) and PPh3 in 1:1:2 molar ratio (Cu:H2tuc:PPh3) as well as that of copper(I) thiocyanate with pyridine-2-thione (pySH) or pyrimidine-2-thione (pymSH) and PPh3 in similar ratio, yielded an iodo-bridged unsymmetrical dimer, [(PPh3)2(mu-I)2Cu(PPh3)] 3 and thiocyanate bridged symmetrical dimer, [(PPh3)2Cu(mu-N,S- SCN)2Cu(PPh3)2] 4, respectively. In both the latter reactions, thio-ligands which initially bind to Cu metal center, are de-ligated by PPh3 ligand.

Antifouling booster biocide extraction from marine sediments: a fast and simple method based on vortex-assisted matrix solid-phase extraction

This paper reports the development of an analytical method employing vortex-assisted matrix solid-phase dispersion (MSPD) for the extraction of diuron, Irgarol 1051, TCMTB (2-thiocyanomethylthiobenzothiazole), DCOIT (4,5-dichloro-2-n-octyl-3-(2H)-isothiazolin-3-one), and dichlofluanid from sediment samples. Separation and determination were performed by liquid chromatography tandem-mass spectrometry. Important MSPD parameters, such as sample mass, mass of C18, and type and volume of extraction solvent, were investigated by response surface methodology. Quantitative recoveries were obtained with 2.0?g of sediment sample, 0.25?g of C18 as the solid support, and 10?mL of methanol as the extraction solvent. The MSPD method was suitable for the extraction and determination of antifouling biocides in sediment samples, with recoveries between 61 and 103% and a relative standard deviation lower than 19%. Limits of quantification between 0.5 and 5?ng?g?1 were obtained. Vortex-assisted MPSD was shown to be fast and easy to use, with the advantages of low cost and reduced solvent consumption compared to the commonly employed techniques for the extraction of booster biocides from sediment samples. Finally, the developed method was applied to real samples. Results revealed that the developed extraction method is effective and simple, thus allowing the determination of biocides in sediment samples.

Electrochemical Characterization of CuSCN Hole-Extracting Thin Films for Perovskite Photovoltaics

CuSCN thin films (optimized previously for perovskite photovoltaics) are deposited on glass, F:SnO2 (FTO), Au, glass-like carbon (GC), and reduced graphene oxide (rGO). They exhibit capacitive charging in an electrochemical window from ca. -0.3 to 0.2 V vs Ag/AgCl. Outside this window, CuSCN film is prone to chemical and structural changes. Anodic breakdown (at ca. 0.5 V) causes restructuring into submicrometer particles and denuding of the substrate. The natural p-doping is demonstrated by both the Hall effect and Mott-Schottky plots from electrochemical impedance. The corresponding flatband potentials (in V vs Ag/AgCl) varied with the substrate type as follows: 0.12 V (CuSCN@FTO), 0.08 V (CuSCN@Au), -0.02 V (CuSCN@GC), and 0.00 V (CuSCN@rGO). The acceptor concentrations determined from electrochemical impedance spectroscopy are by orders of magnitude larger than those from electrical conductivity and the Hall effect, the latter being regarded correct. Raman spectra confirm that thiocyanate is the dominating structural motif over the isomeric isothiocyanate. In situ Raman spectroelectrochemistry discloses substrate-specific intensity changes upon electrochemical charging. The blocking function is tested by a newly designed redox probe, Ru(NH3)63+/2+. It not only has the appropriate redox potential for testing of the CuSCN films but also avoids complications of the standard “ferrocyanide test” which is normally used for this purpose. The perovskite solar cells exhibit better solar conversion efficiency, fill factor, and open-circuit voltage for the rGO-containing devices, which is ascribed to a larger driving force for the hole injection from CuSCN into rGO.
