Stability of organometal halide perovskite solar cells and role of HTMs: Recent developments and future directions

Perovskite solar cells (PSCs) have recently emerged as one of the most exciting fields of research of our time, and the World Economic Forum in 2016 recognized them as one of the top 10 technologies in 2016. With 22.7% power conversion efficiency, PSCs are poised to revolutionize the way power is produced, stored and consumed. However, the widespread use of PSCs requires addressing the stability issue. Therefore, it is now time to focus on the critical step i.e. stability under the operating conditions for the development of a sustainable and durable PV technology based on PSCs. In order to improve the stability of PSCs, hole transport materials (HTMs) have been considered as the paramount components. This is due to the fact that most of the organic HTMs possess a hygroscopic and acidic nature that leads to poor stability of the PSCs. This article reviews briefly but comprehensively the environmental stability issues of PSCs, fundamentals, strategies for improvement, the role of HTMs towards stability and various types of HTMs. Also the environmental parameters affecting the performance of perovskite solar cells including temperature, moisture and light soaking environment have been considered.

Colloidal CZTS nanoparticles and films: Preparation and characterization

Cu2ZnSnS4 (CZTS) compound semiconductor has the advantage of good matching with solar radiation in optical band-gap, large absorption coefficient, non-toxic and especially large abundance ratios of elements, so that CZTS has been considered as a good absorber layer used for the thin-film solar cells with most industrialization promising and environment friendly. In the present work, colloidal CZTS nanocrystals (average size ~8-16 nm) with the band gap of ~1.5 eV were synthesized via wet-chemical processing, using oleylamine (OLA) as solvent and capping molecules. The colloids were characterized by X-ray diffraction (XRD), Raman spectroscopy, transmission electron microscopy (TEM), scanning electron microscopy (SEM) and UV-Vis-NIR spectroscopy. The structure and morphology of nanocrystals were influenced with the reaction temperature. The resulting nanocrystals were kesterite-phase CZTS when the reaction temperature was lower, but were wurtzite-phase CZTS when the reaction temperature above 275 C. The CZTS films on glass substrates were prepared by drop-casting, from the colloidal 10 wt% CZTS-toluene solution where the CZTS colloids were synthesized at 260 C with three different recipes. The resulting films with different heat-treatments were investigated by XRD, SEM and energy dispersive spectroscopy (EDS). Densified CZTS films (5 lm in thickness) could be obtained by drying and sintering in vacuum. The CZTS films have the band-gap around 1.6-2.0 eV, due to Zn rich and S poor in the films. The dark conductivity and photoconductivity under AM 1.5 irradiation of the CZTS films on ITO glass substrates with different heat-treatments were measured by the AC impedance method.

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 13395-16-9 is helpful to your research. Product Details of 13395-16-9

Assembly of novel 2D and 3D heterometallic SbIII-CuI polymers based on antimony(III) thiolates as metallothiolato ligands

A new type of neutral heterometallic SbIII-CuI thiolate coordination polymer has been synthesized under solvothermal conditions by using antimony(III) thiolates as metalloligands and CuSCN as the source of the second metal ion. Reaction of [Sb(edt)Cl] (1) (edt = ethane-1,2-dithiolate) with 1 equivalent of CuSCN affords [{Sb2(edt) 2(mu3-S)CuCl(CuSCN)}n] (2), which features a 2D layer consisted of -CuSCNCuSCN-chains and {Sb2(edt) 2(mu3-S)CuCl} units. During the reaction, 1 was converted into a sulfur-bridged dimer Sb(edt)2S, which behaves simultaneously as a bridging and chelating ligand through all of its sulfur atoms to connect four Cu+ ions in the framework structure of 2. Replacement of Cl- in 1 with pymt-gives a new antimony(III) thiolate formulated as [Sb(edt)-(pymt)] (3) (pymt = 2-pyrimidinethiol), which was further treated with CuSCN to afford coordination polymers [{[Sb(edt)(pymt)] 2(CuSCN)3}n] (4) and [{[Sb(edt)(pymt)]-(CuSCN) 2}n] (5). In the assemblies of 4 and 5, the structure of 3 remains intact and the whole compound serves as a multidentate ligand through Sedt and Npymt atoms to Cu+ ions. Complex 4 also contains -CuSCNCuSCN- chains, which are linked by tridentate {Sb(edt)(pymt)} fragments to form a 2D polymer. Complex 5 is a 3D architecture with {Sb(edt)(pymt)} units acting as bidentate bridging ligand to link the (CuSCN)n layers and {(CuSCN)2}n columns. Complexes 2-5 showed optical transitions with band gaps of 2.66 to 3.41 eV, and their optical properties were studied by DFT calculations. Wiley-VCH Verlag GmbH & Co. KGaA, 2009.

Aerobic oxidation of substituted phenols catalysed by metal acetylacetonates in the presence of 3-methylbutanal

The aerobic oxidation of substituted phenols with the catalytic system M(acac)n/3-methylbutanal/O2 has been investigated. Co(acac)2 and Mn(acac)3 promoted the transformation of 2,6-dimethylphenol and 2,6-di-t-butylphenol into their corresponding diphenoquinones and benzoquinones. In the oxidation of 2,3,6-trimethylphenol, the same catalysts yielded 32-34% of the relevant biphenol. Cu(acac)2 converted 2-naphthol into 1,1?-bi-2-naphthol with 84% yield. Supported Co(II) and Cu(II) complexes have also been used as heterogeneous catalysts for the oxidation of 2,6-di-t-butylphenol and 2-naphthol, respectively.

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.
