Biophotovoltaics: Natural pigments in dye-sensitized solar cells

Dye-sensitized solar cells (DSSCs) which are also called Graetzel cells are a novel type of solar cells. Their advantages are mainly low cost production, low energy payback time, flexibility, performance also at diffuse light and multicolor options. DSSCs become more and more interesting since a huge variety of dyes including also natural dyes can be used as light harvesting elements which provide the charge carriers. A wide band gap semiconductor like TiO2 is used for charge separation and transport. Such a DSSC contains similarities to the photosynthetic apparatus. Therefore, we summarize current available knowledge on natural dyes that have been used in DSSCs which should provide reasonable light harvesting efficiency, sustainability, low cost and easy waste management. Promising natural compounds are carotenoids, polyphenols and chlorophylls.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. category: copper-catalyst, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1111-67-7, in my other articles.

Highly efficient perovskite light-emitting devices containing a cuprous thiocyanate hole injection layer

Inorganic charge transporting materials offer numerous advantages over their organic counterparts, including high charge carrier mobility, stability, simple preparation, and low cost, and have been studied for perovskite optoelectronic devices. However, the majority of these materials strongly quench perovskite luminescence, which is detrimental to the performance of perovskite light-emitting devices. To overcome this and obtain good quality perovskite films, an organic interlayer modified with UV ozone is used. The effects of the UV ozone treatment on the energetics and chemical structures of the organic interlayer are examined. On the basis of this strategy, we fabricate perovskite light-emitting devices that contain a cuprous thiocyanate hole injection layer, which exhibit an improved external quantum efficiency of 10.2% and greater operational stability when compared with the devices that contain a conducting-polymer hole injection layer.

Copper(n) complexes of hydroquinone-containing Schiff bases. towards a structural model for copper amine oxidases

Complexation of the preformed ligand 2,5-dihydroxy-Ar-{pyridin-2-ylmethyl}-benzylideneamine (HL1) with hydrated Cu(BF42) afforded [{Cu(u-L’)}2][BF4]j 1. The crystal structure of l-MeNO2 shows a dimer of near-planar copper(n) ions, with a bridging apical BF4- anion. Variable temperature susceptibility measurements showed the copper(n) ions in 1 to be moderately antiferromagnetically coupled. The complexes [CuL2]X (X- = C1O4″ 2, NO3″ 3, CP 4 or NCS5) and [CuL3]ClO4 (6; HL2 = A-{pyridin-2-ylmethyl}-A f’-{2,5-dihydroxybenzylidene}-l,2-diaminoethane, HL3 = A{pyridin-2-ylmethyl}-Ar’-{2,4,5-trihydroxybenzylidene}-l,2-diaminoethane) have been prepared by template condensation of Apyridin-ylmethylH–diaminoethane with the appropriate benzaldehyde derivative and copper salt. The single crystal structure of 2 shows a near-planar four-co-ordinate copper(n) centre, with a non-co-ordinated C1O4- anion. The chelate ligand backbone is disordered over two orientations, which correspond to different patterns of intermolecular hydrogen bonding in the lattice. UV/vis and EPR data in dmf solution suggest that 2-6 all undergo solvolysis to form an identical [CuL(dmf)Jt (x = 0-2) species in solution. Cyclic voltammograms of HL1 and 1-6 are complex, and demonstrate rapid acid-catalysed decomposition of the benzoquinonecarbaldimine ligand oxidation products. The Royal Society of Chemistry 2000.

Air free fast solution annealing method for perovskite solar cells

The low temperature fast solution annealing (FSA) concept is used for the deposition of perovskite film. In this simple method, a spin coated perovskite film was subsequently immersed into hot (80?C) anti-solvent chlorobenzene. For this solution annealing process, sophisticated lab facility is not required to prevent humidity and moisture. Performance of devices, fabricated by FSA method using methylammonium lead iodide (MAPbI3) perovskite with two different hole transport materials (HTMs), was investigated. The power conversion efficiency (PCE) obtained for copper(I) thiocyanate (CuSCN) and 2,2?,7,7?-tetrakis[N,N-di(4-methoxyphenyl)amino]-9,9?-spirobifluorene (Spiro-OMeTAD) HTMs were 10.02% and 12.10%, respectively.

Two different 1D-chains in the structures of the copper(I) coordination polymers based on bidentate Schiff-base building units and thiocyanate anions as bridging ligands

The reaction of the bidentate Schiff-base ligands (3,4,5-MeO-ba)2en (L1) and (4-Me-ba)2en (L2) with Cu(SCN) in CH3CN yielded two copper(I) coordination polymers [Cu(L1)(SCN)]n (1) and [Cu(L2)(SCN)]n (2), which have been characterized by elemental analyses, IR- and 1H NMR-spectroscopy, and X-ray crystallography. The non-centrosymmetric structures of both Cu(I) complexes consist of an one-dimensional polymeric chain in which copper(I) ions are bridged by two thiocyanate groups bonding in an end-to-end fashion. The Cu(I)?Cu(I) separation is 5.604 A in 1 and 5.706 A in 2.

Three pillared-layered inorganic-organic hybrid polymers with efficient luminescence

Three pillared-layered inorganic-organic hybrid polymers, namely, [Cu2(4,4?-Hbpt)(SCN)2]n (1), [Cd(4,4?-Hbpt)(SCN)2]n (2), and [Cd(4,4?-Hbpt)(SCN)2¡¤CH3CN]n (3) were synthesized via layer diffusion methods. In all three complexes, there exist 2-D neutral wave-like d10 metal thiocyanate layers (for 1, [Cu2(SCN)2]n, and for 2 and 3, [Cd(SCN)2]n) with (4, 4) topology, which are further connected by bidentate 4,4?-Hbpt ligands to form 3-D structures with the primitive cubic topology. The results of photoluminescence and thermogravimetric analyses indicate that the three complexes are good candidates as luminescent materials. This paper provides a strategy to synthesize a novel family of pillared-layered inorganic-organic hybrid polymers constructed with layered d10 metal thiocyanate layers and conjugated organic spacers at the molecular engineering level, as well as the discovery of new patterns of crystallization at the crystal engineering level.

Fabrication of CH3NH3PbI3 perovskite-based solar cells: Developing various new solvents for CuSCN hole transport material

Copper (I) thiocyanate (CuSCN) is a cost-competitive hole selective contact for the emerging organic-inorganic hybrid perovskite solar cells. However, limitation of solvent is the main issue for getting an optimal thickness for pin-hole free selective contacts. We have developed various solvents such as mixture of propylsulfide with chlorobenzene (1:1), isopropanol with methylammonium iodide (10 mg/ml) and propylsulfide + isopropanol (1:2) + MAI (10 mg/ml) for dissolving CuSCN. It was found that perovskite layer was more stable once CuSCN coating laid on the top surface using the propylsulfide + isopropanol (1:2) + MAI (10 mg/ml) solvent than conventional propylsulfide by doctor blade technique. By employing low temperature solution-process techniques, power conversion achieved over 10% under full sun illumination by the proposed mixed solvent. CuSCN continues to offer promise as a chemically stable and straightforward replacement for the commonly used expensive organic hole conductor (2,2?,7,7?-tetrakis-(N,N-di-p-methoxyphenylamine)9,9?-spirobifluorene (Spiro-OMeTAD)).

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 1111-67-7, and how the biochemistry of the body works.Application of 1111-67-7

Improved CuSCN-ZnO diode performance with spray deposited CuSCN

P-type copper(I) thiocyanate (beta-CuSCN) was deposited using a pneumatic micro-spray gun from a saturated solution in propyl sulphide. An as-produced 6 mum CuSCN film exhibited a hole mobility of 70 cm 2/V¡¤s and conductivity of 0.02 S¡¤m-1. A zinc oxide (ZnO) nanorod array was filled with CuSCN, demonstrating the capability of the process for filling nanostructured materials. This produced a diode with a n-type ZnO and p-type CuSCN junction. The best performing diodes exhibited rectifications of 3550 at ¡À 3 V. The electronic characteristics exhibited by the diode were attributed to a compact grain structure of the beta-CuSCN giving increased carrier mobility and an absence of cracks preventing electrical shorts between electrode contacts that are typically associated with beta-CuSCN films.
