The energy structure of PEDOT:PSS limits the perovskite solar cell (PSC) performance based on inverted FTO/PEDOT:PSS/perovskite/PCBM structure. Here, inorganic CuSCN is modified on PEDOT:PSS using spin-coating method under low temperature, which is compatible with the low temperature fabrication of PSC. Modification CuSCN guarantees the light harvesting of perovskite layer because of the transparency of CuSCN and good crystalline of perovskite film on CuSCN/PEDOT:PSS substrate. Furthermore, CuSCN effectively changes the energy states of PEDOT:PSS to decrease the energy loss during charge transport, promoting the charge transfer at the same time. Based on the improved charge transport and reduced energy loss, the photovoltaic property of PSC based on CuSCN/PEDOT:PSS reaches the optimized efficiency of 10.9%, much better than the control PEDOT:PSS-based device with 9.1% performance (AM1.5, 1sun).

Solid-state dye-sensitized solar cells currently suffer from issues such as inadequate nano-pore filling, low conductivity and crystallization of hole-transport materials infiltrated in the mesoscopic TiO2 scaffolds, leading to low performances. Here we report a record 11% stable solid-state dye-sensitized solar cell under standard air mass 1.5 global using a hole-transport material composed of a blend of [Cu (4,4?,6,6?-tetramethyl-2,2?-bipyridine)2](bis(trifluoromethylsulfonyl)imide)2 and [Cu (4,4?,6,6?-tetramethyl-2,2?-bipyridine)2](bis(trifluoromethylsulfonyl)imide). The amorphous Cu(II/I) conductors that conduct holes by rapid hopping infiltrated in a 6.5 mm-thick mesoscopic TiO2 scaffold are crucial for achieving such high efficiency. Using time-resolved laser photolysis, we determine the time constants for electron injection from the photoexcited sensitizers Y123 into the TiO2 and regeneration of the Y123 by Cu(I) to be 25 ps and 3.2 ms, respectively. Our work will foster the development of low-cost solid-state photovoltaic based on transition metal complexes as hole conductors.

A facile and efficient transformation of arylboronic acids to their corresponding aryl thiocyanates has been successfully developed. Based on the CuCl-catalyzed oxidative cross-coupling reaction between arylboronic acids and trimethylsilylisothiocyanate (TMSNCS) under oxygen atmosphere, the transformation can be readily conducted at ambient temperature. The newly-developed protocol provided a competitive synthetic approach to aryl thiocyanates that can tolerate a broad range of reactive functional groups and/or strong electron-withdrawing groups.

Three Cu-based coordination polymers (CPs), including [Cu II(N- eta 1-NCS) 2(O- eta 1-DMF) 2(mu 2-3,3′-bptz)] n (1), [Cu I(1,3- mu 2-NCS)(mu 2-3,3′-bptz)] n (2) and [(Cu I(1,3- mu 2- NCS))(mu 2-4,4′-bptz)] n (3) (DMF = N, N-dimethyl formamide, 3,3′-bptz = 3,6-bis(3-pyridyl)tetrazine and 4,4′-bptz = 3,6-bis(4-pyridyl)tetrazine) have been successfully constructed by solution diffusion reactions by using Cu(NO 3) 2.3H 2O or CuNCS and KNCS with 3,3′-bptz / 4,4′-bptz ligands, respectively. The resulting crystalline materials have been characterized by the single-crystal X-ray diffraction analyses, elemental analyses, FT-IR spectra, thermogravimetric analyses and powder X-ray diffraction (PXRD). Single crystal X-ray analyses revealed that CP 1 is organized in one-dimensional (1D) chain in which the Cu(II) ions are coordinated by eta 1-NCS – anions and eta 1-DMF molecules, and linked by mu 2-3,3′-bptz bridging ligands. CPs 2 and 3 are structural isomers. CP 2 exhibits two-dimensional (2D) (4,4)-plane-like network in which Cu(I) ions are linked by mu 2-NCS – and mu 2-3,3′-bptz ligands. In CP 3, Cu(I) ions are connected by mu 2-NCS – and mu 2-4,4′-bptz ligands to form 2D saw-tooth wavy network. In addition, the photoluminescence properties of CPs 1-3 were also investigated in the solid state at room temperature.

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.
