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.

Organic light-emitting diodes with an electro-deposited copper(I) thiocyanate (CuSCN) hole-injection layer based on aqueous electrolyte

Copper(I) thiocyanate (CuSCN) has been drawing much attention in optoelectronics due to its exceptional optical and electrical properties, as well as its processing versatility. The first organic light-emitting diodes (OLEDs) integrated with electro-deposited CuSCN crystalline thin films based on aqueous electrolyte were fabricated. With precisely tuned deposition parameters, the CuSCN thin films with satisfactory surface roughness and sufficient grain density were realized. We found that the driving voltage (voltage at a current density of 100 mA/cm2) and turn-on voltage of OLEDs using CuSCN as the hole injection layer (HIL) can be reduced by 1.41 and 1.79 V, respectively, compared with devices using vacuum-deposited hole injecting transition metal oxide molybdenum trioxide (MoO3). Moreover, the fabricated OLEDs also demonstrated considerably mitigated efficiency roll-off. Optical and energetic analyses were conducted to investigate the characteristics and enhancement mechanisms. Efficient hole-injection, electron blocking, improved charge balance, enhanced optical properties and good compatibility of electro-deposited CuSCN with thermally evaporated organic systems were found to be the primary contributors for the performance improvements of the OLEDs.

Vibrational Relaxation Dynamics of a Semiconductor Copper(I) Thiocyanate (CuSCN) Film as a Hole-Transporting Layer

The semiconductor CuSCN film, which is typically used as the hole-transporting layer (HTL) in solar cell studies, has been investigated by Fourier transform infrared (FTIR) spectroscopy and ultrafast transient infrared (IR) spectroscopy. A sharp peak at 2175 cm-1 corresponding to the CN vibrational stretching mode in CuSCN was observed, and the peak frequency remained unchanged by varying the thickness of the CuSCN thin film. Vibrational relaxation measurements showed that the 0-1 and 1-2 transitions of CN stretching can be observed at 2175 and 2140 cm-1, respectively. The heat-induced absorption and bleaching peaks (2167 and 2175 cm-1) can be clearly seen at a waiting time of 40 ps. The vibrational relaxation of the CN stretching mode determined from the 1-2 transition exhibited a biexponential decay with time constants of 7.4 ¡À 0.5 (90%) and 158 ¡À 50 ps (10%). Importantly, the abnormal anisotropy decay of the CN stretching mode in the CuSCN thin film was also observed for the first time. A detailed analysis showed that the distinct anisotropy decay curve could be described using a triexponential decay function, which was explained by three different processes: Resonance energy transfer (?8 ps), a thermalization process (?40 ps), and molecular rotation (?150 ps). The time scale of the thermalization process caused by the vibrational relaxation in CuSCN is at a time scale of 40 ps, which is important for us to understand the thermally activated charge-transport property of the CuSCN film employed as the HTL. Further UV pump-IR probe measurement revealed that the carrier scattering and relaxation processes in the CuSCN film are strongly associated with the vibrational excitation and relaxation dynamics of the CN stretching mode. It is expected that the fundamental understanding of the vibrational relaxation dynamics of the CuSCN thin film should provide helpful insight to elucidate its role as the HTL in solar cell studies at the molecular level.

Separation of propylene and propane by alkylimidazolium thiocyanate ionic liquids with Cu+ salt

Ionic liquids (ILs) coupled with Ag+ or Cu+ salts to form a new kind of reactive absorbent have been studied to separate light olefin from paraffin recently. In this work, we prepared two halogen-free alkylimidazolium thiocyanate ILs with cheaper cuprous thiocyanate, i.e., [Bmim]SCN-CuSCN and [Emim]SCN-CuSCN (Bmim, 1-butyl-3-methylimidazolium; Emim, 1-ethyl-3-methylimidazolium) and investigated their absorption capability for propylene, propane and mixture of both at 1-7 bar and 298-318 K. The effects of operating parameter including cation nature, temperature, pressure, Cu+ concentration and reuse of absorbent were investigated. Propylene shows a chemical absorption while propane does a physical one, and increasing Cu+ concentration effectively improves the absorption capability for propylene and the selectivity of propylene/propane. [Bmim]SCN-CuSCN has higher absorption capability and selectivity for propylene than [Emim]SCN-CuSCN, e.g., [Bmim]SCN-CuSCN-1.5 M can absorb 0.12 mol of propylene per liter while 0.012 mol of propane per liter at 1 bar and 298 K, with a selectivity of 10, which is comparable to some other ILs-Ag+ salts and better than pure ILs. Such absorbents can be regenerated through temperature and pressure swing without remarkable activity loss. This work shows that alkylimidazolium thiocyanate ILs with Cu+ salts are promising reactive absorbents to separate propylene from propane.

Versatility of the nature of the magnetic Cu(II)-U(IV) interaction. Syntheses, crystal structures and magnetic properties of Cu2U and CuU compounds

Treatment of [M(H2Li)] with U(acac)4 in refluxing pyridine led to the formation of the trinuclear complexes [{MLi(py)x}2U] [L1 = N,N?-bis(3-hydroxysalicylidene)-2,2-dimethyl-1,3-propanediamine and M = Ni, Cu or Zn; L2 = N,N?-bis(3-hydroxysalicylidene)-1,3-propanediamine and M = Cu or Zn; L3 = N,N?-bis(3-hydroxysalicylidene)-2-methyl-1,2-propanediamine and M = Ni, Cu or Zn; x = 0 or 1]. The dinuclear compounds [ML3(py)U(acac)2] (M = Cu, Zn) were isolated from the reaction of [M(H2L3)] and U(acac)4 in pyridine at 60C. The crystal structures of the trinuclear complexes are built up by two orthogonal MLi(py)x units which are linked to the central uranium ion by the two pairs of oxygen atoms of the Schiff base ligand; the U(IV) ion is found in the same dodecahedral configuration but the Cu(II) ion coordination geometry and the Cu … U distance are different by passing from L1 or L2 to L3, due to the shortening of the diimino chain of L3. These geometrical parameters seem to have a great influence on the magnetic behaviour of the complexes since the Cu-U coupling in [{CuLi(py)x}2U] (i = 1, 2) is ferromagnetic while it is antiferromagnetic in [{CuL3(py)x}2U]. In the compounds [{CuL3(py)x}2U] and [CuL3(py)U(acac)2], the Cu coordination and the Cu … U distance are very similar, and both exhibit an antiferromagnetic interaction.

Copper catalyzed oxidative coupling of ortho-vinylanilines with N-tosylhydrazones: Efficient synthesis of polysubstituted quinoline derivatives

Efficient and general copper catalyzed oxidative cyclization of ortho-vinylaniline has been accomplished employing N-tosylhydrazone as coupling partner. Various substituted quinoline derivatives of biological importance were achieved in good to excellent yield. The important features are the high functional group tolerates, up-gradation to gram scale synthesis and possible one-pot synthesis of quinoline from corresponding carboxaldehyde. Synthetic potential of the obtained quinoline derivatives was demonstrated through C-H bond functionalization reaction. Furthermore, preliminary mechanistic investigation revealed the possible generation of non-stabilized diazo compound and imine derivative as potential intermediates as well as copper catalyzed electrocyclic reaction and oxidative aromatization.
