《Effects of co-Addition of sodium chloride and copper(II) bromide to mixed-cation mixed-halide perovskite photovoltaic devices》 was written by Ueoka, Naoki; Oku, Takeo. HPLC of Formula: 7789-45-9 And the article was included in ACS Applied Energy Materials in 2020. The article conveys some information:
The effects of the co-addition of NaCl and CuBr2 to CH3NH3PbI3-xClx-based photovoltaic devices are investigated. The lattice constant of CH3NH3Pb(Cu)I3-xClx(Br) is slightly increased by the addition of NaCl, and the X-ray diffraction peaks corresponding to the tetragonal symmetry disappears after several weeks, which indicates a structural transition from the tetragonal to the cubic system by the co-addition of NaCl and CuBr2. A microstructural model, where Na occupies the CH3NH3 vacancy site, is proposed. The Jahn-Teller effect of the Cu d electrons leads to the formation of a cubic system at elevated temperatures, and the conversion efficiency is maintained for 10 wk for the device with a co-addition of CuBr2 and NaCl.Cupric bromide(cas: 7789-45-9HPLC of Formula: 7789-45-9) was used in this study.
Cupric bromide(cas: 7789-45-9) can be used as reducing agent, when complexed by three molecules of pyridine initiators for the controlled polymerization of styrene, methyl acrylate and methyl methacrylate.HPLC of Formula: 7789-45-9
