The rapid increase in the efficiency of perovskite solar cells (PSCs) in last few decades have made them very attractive to the photovoltaic (PV) community. However, the serious challenge is related to the stability under various conditions and toxicity issues. A huge number of articles have been published in PSCs in the recent years focusing these issues by employing different strategies in the synthesis of electron transport layer (ETL), active perovskite layer, hole transport layer (HTL) and back contact counter electrodes. This article tends to focus on the role and classification of different materials used as HTL in influencing long-term stability, in improving the photovoltaic parameters and thereby enhancing the device efficiency. Hole Transport Materials (HTMs) are categorized by dividing into three primary types, namely; organic, inorganic and carbonaceous HTMs. To analyze the role of HTM in detail, we further divide these primary type of HTMs into different subgroups. The organic-based HTMs are subdivided into three categories, namely; long polymer HTMs, small molecule HTMs and cross-linked polymers and the inorganic HTMs have been classified into nickel (Ni) derivatives and copper (Cu) derivatives based HTMs, p-type semiconductor based HTMs and transition metal based HTMs. We further analyze the dual role of carbonaceous materials as HTM and counter electrode in the perovskite devices. In addition, in this review, an overview of the preparation methods, and the influence of the thickness of the HTM layers on the performance and stability of the perovskite devices are also provided. We have carried out a detailed comparison about the various classification of HTMs based on their cost-effectiveness and considering their role on effective device performance. This review further discusses the critical challenges involved in the synthesis and device engineering of HTMs. This will provide the reader a better insight into the state of the art of perovskite solar devices.

Nitrogen/carbon layer coordinated transition metal complexes are the most important alternatives to improve the catalytic performance of catalysts for energy storage and conversion systems, which require systematic investigation and improvement. The coordination mode of transition metal ions can directly affect the catalytic performance of catalysts. Herein, this paper reports that two kinds of Cu-based composites (CuSCN and CuSCN/C3N4) are prepared by in situ controllable crystallization of copper foam (CF) through electropolymerization and calcination. As a comparison, it is clarified that the different coordination modes of Cu1+ ions determine the different catalytic properties. The samples can be switched freely by tuning the electropolymerization period, which leads to different coordination modes of Cu1+ ions dramatically, thus affecting the electrocatalytic performance of composite materials for the hydrogen evolution reaction (HER) in turn. Thorough characterization using techniques, including X-ray photoelectron spectroscopy (XPS) and synchrotron-based near edge X-ray absorption fine structure (EXAFS) spectroscopy, reveals that strong interactions between CuSCN and C3N4 of CuSCN/C3N4 facilitate the formation of subtle coordinated N-Cu-S species, of which electronic structures are changed. Density Functional Theory (DFT) calculations indicate that the electrons can penetrate from CuSCN to N atoms present in C3N4. As a result, CuSCN/C3N4 demonstrates a better catalytic performance than the conventional transition-metal-based electrocatalysts. Besides, CuSCN/C3N4 reflects almost identical hydrogen evolution reaction (HER) activity and stability in an acid electrolyte with Pt/C.

The first two inorganic-organic hybrid three-dimensional (3D) polyoxotantalates (POTas) and the first two inorganic-organic hybrid 2D POTas have been obtained. All of these high-dimensional POTas are built from a new-type POTa dimeric cluster {Cu(en)(Ta6O19)}2/{Cu(enMe)(Ta6O19)}2 (en = ethylenediamine, enMe = 1,2-diaminopropane) bridged by copper complexes. Interestingly, extended POTas 1 and 3 can undergo single-crystal to single-crystal structural transformations triggered by water.

We report on low operating voltage thin-film transistors (TFTs) and integrated inverters based on copper(I) thiocyanate (CuSCN) layers processed from solution at low temperature on free-standing plastic foils. As-fabricated coplanar bottom-gate and staggered top-gate TFTs exhibit hole-transporting characteristics with average mobility values of 0.0016 cm2 V?1 s?1 and 0.013 cm2 V?1 s?1, respectively, current on/off ratio in the range 102-104, and maximum operating voltages between ?3.5 and ?10 V, depending on the gate dielectric employed. The promising TFT characteristics enable fabrication of unipolar NOT gates on flexible free-standing plastic substrates with voltage gain of 3.4 at voltages as low as ?3.5 V. Importantly, discrete CuSCN transistors and integrated logic inverters remain fully functional even when mechanically bent to a tensile radius of 4 mm, demonstrating the potential of the technology for flexible electronics.

Structural versatility and electronic structures of copper(i) thiocyanate (CuSCN)-ligand complexes

Copper(i) thiocyanate (CuSCN) is a promising semiconductor with an expansive range of applications already demonstrated. Belonging to the group of coordination polymers, its structure can be easily modified, for example via ligand (L) coordination. In this work, we have analyzed in detail the crystal structures of 26 CuSCN-L complexes that exhibit diverse structures changing from the 3D networks of the parent CuSCN to 2D sheet, 1D ladder, 1D zigzag chain, 1D helical chain, and a 0D monomer as well as intermediate bridged structures. We outline herein the basic structural design principles based on four factors: (1) Cu(i) geometry, (2) CuSCN?:?L ratio, (3) steric effects, and (4) supramolecular interactions. In addition, we employ density functional theory to study the electronic structures of these 26 complexes and find that the opto/electronic properties vary over a wide range, e.g., widened or reduced fundamental band gaps, restricted hole transport due to Cu-SCN network disruption, and the possibility of electron transport through the ligand states. We also observe a correlation between the electronic properties and the dimensionality of the Cu-SCN network. Lowering the dimensionality of the 3D structure to 2D, 1D, and 0D by increasing the number of coordinating ligands, the dispersion and the width of the top valence bands decrease whereas the energy difference between the Cu and SCN states expands. Aliphatic ligands in most cases do not generate electronic states in the band gaps whereas aromatic ligands give rise to states between the Cu and SCN states that lead to optical absorption and emission in the visible range. This study provides guidelines for developing coordination polymer semiconductors based on the Cu-SCN network. The 2D structure is identified as a promising platform for designing new CuSCN-based materials as it retains the carrier transport properties while allowing for properties tailoring through ligand coordination.

Dependence of Tc on hydrostatic pressure in beta?-(ET)2SF5CH2CF2SO 3 and kappa-(ET)2Cu(NCS)2

The dependence of Tc on hydrostatic (He-gas) pressure is determined for the recently discovered organic superconductor beta?-(ET)2SF5CH2CF2SO 3 [ET = bis(ethylenedithio)-tetrathiafulvalene] with Tc(0) ? 5 K, yielding the pressure derivative dTc/dP ? -1.34 K kbar-1. The present experiments also included kappa-(ET)2Cu(NCS)2 where we find the extremely large value dTc/dP ? -3.84 K kbar-1, in agreement with earlier studies. For both samples the pressure dependence Tc(P) does not depend on the temperature at which the pressure is changed.

Novel mixed-metal-alkynyl complexes stabilised by di-imine ligands: Synthesis, characterisation and electrochemistry of [(tBu2bipy)Pt(C?CR)2M(SCN)] (R = C6H4Me, SiMe3; M = Cu, Ag)

Reaction of (4,4?-bis-tert-butyl-2,2?-dipyridyl) platinum bis-alkynyl [(tBu2bipy)Pt(C?CR)2] (R = C6H4Me 1a, SiMe3 1b) with Group 11 metal thiocyanate salts (M = Cu, Ag) affords 1:1 mixed-metal complexes [(tBu2bipy)Pt(C?CR)2M(SCN)] (M = Cu, R = C6H4Me 2a, SiMe3 2b; M = Ag, R = C6H4Me 3a, SiMe3 3b). X-ray analyses of the complexes 2a and 3b show that the group 11 metal is bonded in an eta2 fashion to two carbon-carbon triple bonds so that the co-ordination geometry is trigonal planar. The Pt atom geometry in both complexes is square planar. An electrochemical study of the copper complexes 2a and 2b reveals one fully reversible one electron reduction that is consistent with the first reduction of the co-ordinated bipyridyl ligand. There is also an irreversible one electron oxidation that corresponds to the CuI to CuII transition.

Development of environmentally friendly antifouling paints using biodegradable polymer and lower toxic substances

The development of new antifouling coatings with respect to the marine environment is actually crucial. The aim of the present work is to concept an erodible paint formulated with biodegradable polyester as binders and which combines two modes of prevention: chemical and physical repelling of biofouling. This system is principally dedicated to disturb durable settlement of microfouling. Each component was chosen according to its specific properties: chlorhexidine is a bisdiguanide antiseptic with antibacterial activity, zinc peroxide is an inorganic precursor of high instable entities which react with seawater to create hydrogen peroxide, Tween 85 is a non ionic surfactant disturbing interactions between colonizing organisms and surface. Obtained results highlighted the interest on mixing such molecules to obtain a promising coating with lower toxicity than traditional systems.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Related Products of 1111-67-7, you can also check out more blogs aboutRelated Products of 1111-67-7
