Understanding of perovskite crystal growth and film formation in scalable deposition processes

Hybrid organic-inorganic perovskite photovoltaics (PSCs) have attracted significant attention during the past decade. Despite the stellar rise of laboratory-scale PSC devices, which have reached a certified efficiency over 25% to date, there is still a large efficiency gap when transiting from small-area devices to large-area solar modules. Efficiency losses would inevitably arise from the great challenges of homogeneous coating of large-area high quality perovskite films. To address this problem, we provide an in-depth understanding of the perovskite nucleation and crystal growth kinetics, including the LaMer and Ostwald ripening models, which advises us that fast nucleation and slow crystallization are essential factors in forming high-quality perovskite films. Based on these cognitions, a variety of thin film engineering approaches will be introduced, including the anti-solvent, gas-assisted and solvent annealing treatments, Lewis acid-base adduct incorporation, etc., which are able to regulate the nucleation and crystallization steps. Upscaling the photovoltaic devices is the following step. We summarize the currently developed scalable deposition technologies, including spray coating, slot-die coating, doctor blading, inkjet printing and vapour-assisted deposition. These are more appealing approaches for scalable fabrication of perovskite films than the spin coating method, in terms of lower material/solution waste, more homogeneous thin film coating over a large area, and better morphological control of the film. The working principles of these techniques will be provided, which direct us that the physical properties of the precursor solutions and surface characteristics/temperature of the substrate are both dominating factors influencing the film morphology. Optimization of the perovskite crystallization and film formation process will be subsequently summarized from these aspects. Additionally, we also highlight the significance of perovskite stability, as it is the last puzzle to realize the practical applications of PSCs. Recent efforts towards improving the stability of PSC devices to environmental factors are discussed in this part. In general, this review, comprising the mechanistic analysis of perovskite film formation, thin film engineering, scalable deposition technologies and device stability, provides a comprehensive overview of the current challenges and opportunities in the field of PSCs, aiming to promote the future development of cost-effective up-scale fabrication of highly efficient and ultra-stable PSCs for practical applications.

Construction of 1-2D CuI(or CuII) metal-organic architectures with metal thiocyanates and bipyridyl spacers: Syntheses, structures, and thermal properties

Three new coordination polymers based on IB metal thiocyanates, [CuII(NCS)2(DMSO)4(meso-dpb)]n (1), [Cu2II (NCS)4 (bpp)4]n (2), [CuI(NCS)(pia)]n (3) (dpb = 2,3-di(4-pyridyl)-2,3-butanediol, bpp = 1,3-bis(4-pyridyl)propane, pia = N,N?-(1,2-phenylene)diisonicotinamide), have been synthesized by the pre-assembly method and characterized by X-ray crystallography. In 1, CuII cations are bridged by meso-dpb ligands to form a one-dimensional (1D) linear chain. Compound 2 consists of 2D undulated layers of (4, 4) topology that show twofold parallel interpenetration. In the case of 3, the MI center adopts tetrahedral coordination geometry and the 2D networks are formed by organic ligand with “folding ruler-shaped” NCS–M chains. The thermal properties of 1-3 were also investigated.

Synthesis, structures, luminescence and terahertz time-domain spectroscopy of nine Cu(I) complexes with P^P ligands and 1,10-phenanthroline derivatives

Nine new copper(I) complexes bearing 1,3-bis(diphenylphosphino)propane (dppp) and 4,7-diphenyl-1,10-phenanthroline (batho) or 2,9-dimethyl-1,10-phenanthroline (neo) have been synthesized and characterized. Single crystal X-ray diffraction analysis reveals that complexes 1?4 and 6?9 are mononuclear with similar structures, while complex 5 is a binuclear structure. They display absorption around 280 nm and 410 nm, and the intensive emission in the range of 520?620 nm in the solid state occurring with lifetimes on the mus timescale indicates phosphorescence. Our TD-DFT calculations show that emission from the lowest excited triplet state T1 is of 3MLCT nature. This study manifests that these simple and long-lifetime Cu(I) systems may exhibit a similar, but more complex excited state behavior than the systems previously appreciated.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1111-67-7 is helpful to your research. 1111-67-7

Construction of two unique W/S/Cu cluster-based coordination polymers affected by pseudohalogen ligands

The pseudohalogen ligands affecting the architectures of heterothiometallic Mo(W)/S/Cu(Ag) cluster-based coordination polymers (CPs) was firstly explored. In the presence of CuCN or CuSCN with distinct pseudohalogen ligands, two unique W/S/Cu cluster-based CPs [WS4Cu3(CN)(4,4?-bipy)2]n (1, 4,4?-bipy = 4,4?-bipyridine) and {[WS4Cu4(4,4?-bipy)4][WS4Cu4(SCN)4(4,4?-bipy)2]¡¤0.5DMSO}n (2) were achieved by interdiffusion reaction of (NH4)2WS4 and 4,4?-bipy. 1 and 2 were characterized by X-ray single and powder crystal diffractions, elemental analysis, IR, UV-Vis, thermogravimetric analysis. 1 exhibits a neutral 2-D (4,4) network, fabricated by 4-connected T-shaped [WS4Cu3]+ clusters, single CN- bridges and double 4,4?-bipy bridges. While, 2 possesses an unusual 3-D fourfold non-equivalent interpenetrated architecture, consisting of two cationic and two anionic planar ‘open’ [WS4Cu4]2+ cluster-based frameworks; the cationic and anionic architectures are constructed by double 4,4?-bipy bridges and single 4,4?-bipy bridges, respectively, and all show the diamondoid topologies.

Electronic Modulation of Electrocatalytically Active Center of Cu7S4 Nanodisks by Cobalt-Doping for Highly Efficient Oxygen Evolution Reaction

Cu-based electrocatalysts have seldom been studied for water oxidation because of their inferior activity and poor stability regardless of their low cost and environmentally benign nature. Therefore, exploring an efficient way to improve the activity of Cu-based electrocatalysts is very important for their practical application. Modifying electronic structure of the electrocatalytically active center of electrocatalysts by metal doping to favor the electron transfer between catalyst active sites and electrode is an important approach to optimize hydrogen and oxygen species adsorption energy, thus leading to the enhanced intrinsic electrocatalytic activity. Herein, Co-doped Cu7S4 nanodisks were synthesized and investigated as highly efficient electrocatalyst for oxygen evolution reaction (OER) due to the optimized electronic structure of the active center. Density-functional theory (DFT) calculations reveal that Co-engineered Cu7S4 could accelerate electron transfer between Co and Cu sites, thus decrease the energy barriers of intermediates and products during OER, which are crucial for enhanced catalytic properties. As expected, Co-engineered Cu7S4 nanodisks exhibit a low overpotential of 270 mV to achieve current density of 10 mA cm-2 as well as decreased Tafel slope and enhanced turnover frequencies as compared to bare Cu7S4. This discovery not only provides low-cost and efficient Cu-based electrocatalyst by Co doping, but also exhibits an in-depth insight into the mechanism of the enhanced OER properties.
