From encapsulation to polypseudorotaxane: Unusual anion networks driven by predesigned metal bis(terpyridine) complex cations

Solvothermal reactions of CuSCN, metal (Mn2+, Fe2+, Co2+, Ni2+, Cu2+) sulfate, and terpyridine (2,2?:6?,2?-terpyridine or 4?-p-tolyl-2,2?: 6?,2?-terpyridine) in the presence of triphenylphosphine yielded a series of hybrid coordination compounds, in which in situ formed metal bis(terpyridine) complex cations are encapsulated by a 3D anionic network or entangled by 2D heartlike networks, forming encapsulation or polypseudorotaxane supramolecules. The complex cations play a role as template to direct the fabrication of the structures.

Photoelectrochemistry of electrodeposited Cu2O

The photoelectrochemical properties of electrodeposited Cu2O in aqueous solutions were investigated. The material showed long term stability under illumination at negative potentials. The diffusion length of electrons in the as-deposited material was of the order of 10-100 nm. We did not observe photocathodic reduction of water. The efficiencies for the reduction of oxygen and the methylviologen cation at these electrodes were surprisingly high. This suggests that, in conjunction with a suitable redox system, electrodeposited Cu2O could be a promising material as a p-type photoelectrode in an electrochemical photovoltaic cell.

Thiocyanato complexes of the coinage metals: Synthesis and crystal structures of the polymeric pyridine complexes [AgxCuy(SCN)x+y(py)z]

From solutions of CuSCN or AgSCN in pyridine, several pyridine complexes of the thiocyanates with varying compositions and crystal structures were isolated depending on the reaction conditions. In CuSCN and in the orthorhombic modification of AgSCN the SCN- anions co-ordinate to four metal atoms as 1,1,1,3-mu4 bridges, whereas the degree of bridging decreases with increasing amounts of pyridine in the polymeric complexes [Cu(SCN)(py)z] and [Ag(SCN)(py)z] (z = 1 or 2). The distorted tetrahedral co-ordination of the metal atoms is preserved by co-ordination of pyridine ligands. Especially in the heteronuclear complexes [AgCu(SCN)2(py)4], [AgCu(SCN)2(py)3] and [Ag2Cu(SCN)3(py)3], interesting variants of structures result from the different possible modes of co-ordination of the SCN- ligand and from the preferred co-ordination of the “soft” S atoms to the “soft” Ag+ ions as defined by Pearson’s hard and soft acid and base principle.

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.

Stability improvement under high efficiency?next stage development of perovskite solar cells

With efficiency of perovskite solar cells (PSCs) overpassing 23%, to realize their commercialization, the biggest challenge now is to boost the stability to the same level as conventional solar cells. Thus, tremendous effort has been directed over the past few years toward improving the stability of these cells. Various methods were used to improve the stability of bulk perovskites, including compositional engineering, interface adjustment, dimensional manipulation, crystal engineering, and grain boundary decoration. Diverse device configurations, carrier transporting layers, and counter electrodes are investigated. To compare the stability of PSCs and clarify the degradation mechanism, diverse characterization methods were developed. Overall stability of PSCs has become one central topic for the development of PSCs. In this review, we summarize the state-of-the-art progress on the improvement of device stability and discuss the directions for future research, hoping it provides an overview of the current status of the research on the stability of PSCs and guidelines for future research.

Charge and Triplet Exciton Generation in Neat PC70BM Films and Hybrid CuSCN:PC70BM Solar Cells

Organic solar cells that use only fullerenes as the photoactive material exhibit poor exciton-to-charge conversion efficiencies, resulting in low internal quantum efficiencies (IQE). However, the IQE can be greatly improved, when copper(I) thiocyanate (CuSCN) is used as a carrier-selective interlayer between the phenyl-C70-butyric acid methyl ester (PC70BM) layer and the anode. Efficiencies of ?5.4% have recently been reported for optimized CuSCN:PC70BM (1:3)-mesostructured heterojunctions, yet the reasons causing the efficiency boost remain unclear. Here, transient absorption (TA) spectroscopy is used to demonstrate that CuSCN does not only act as a carrier-selective electrode layer, but also facilitates fullerene exciton dissociation and hole transfer at the interface with PC70BM. While intrinsic charge generation in neat PC70BM films proceeds with low yield, hybrid films exhibit much improved exciton dissociation due to the presence of abundant interfaces. Triplet generation with a rate proportional to the product of singlet and charge concentrations is observed in neat PC70BM films, implying a charge?singlet spin exchange mechanism, while in hybrid films, this mechanism is absent and triplet formation is a consequence of nongeminate recombination of free charges. At low carrier concentrations, the fraction of charges outweighs the population of triplets, leading to respectable device efficiencies under one sun illumination.

mcSi and CdTe solar photovoltaic challenges: Pathways to progress

Multi-crystalline Si (mcSi) and CdTe solar photovoltaic technologies have gained significant improvement. Shockley?Queisser (S?Q) limit consideration further progress of open-circuit voltage (Voc), fill factor (FF) and the efficiency of CdTe cell are anticipated. Sub-bandgap parasitic absorption, grain boundaries and back contacts recombination lessening are vital to minimize these opto-electrical losses. mcSi and CdTe heterojunction (HJ) cells? intrinsic thermal co-efficient to optical (bandgap) loss, interface and bulk defects and related thermal diffusion are possible opto-electrical limitations. Wafer based mcSi passivated emitter rear contact (PERC) and tunnel oxide passivated contact (TOPCon) over Al back surface field (Al-BSF) contact have incredibly progressed in current decades. Similar as mcSi cell, advancement of commercial CdTe cell is desired. Reviewing CdTe and mcSi/cSi (photo-physical similarity) based one hundred and fifty research papers it is comprehended that not only band aligned but also thin, transparent passivation window and electron reflector as barrier are central to minimize the shortcomings. CdTe absorber thickness-dependent Voc and fill factor trade-off while diverse window and barrier layer performance review are realized optical transparencies to electrical loss outcome. Stated opto-electrical development purpose thin absorber supportive band and lattice matching double HJ or graded CdSexTe1-x/CdTe HJ is possible realistic pathways. mcSi thin wafer is exposed to minimize bulk degradation that is caring for a stable and cost-effective PV. Finally, CdTe solar cells present limitations to laboratory design towards the best progression trails are focused. It is anticipated to limit the levelized cost of energy (LCOE).
