記述言語：英語掲載種別：研究論文（学術雑誌）出版者・発行元：Applied Surface Science

© 2019 Electronic structures of alkali metals (Li, Na, K or Rb)-incorporated formamidinium lead halide perovskite compounds were investigated by first-principles calculation. The conduction band were supplied with electrons from energy levels at 2s, 3s, 4s and 5s orbital of alkali metal to energy levels at 6p orbital of Pb atom in the perovskite crystal. Deviation of charge distribution in the perovskite crystal promoted the photo-induced charge generation, electron correlation and electron-lattice interaction as phonon effectiveness. The chemical shifts of 127 I-NMR in the perovskite crystal were originated in a slight perturbation of the coordination structure with nuclear quadruple interaction based on the electric field gradient. The slight incorporation of alkali metal near the ligand structure decreased the enthalpy with the Gibbs free-energy by contribution of the entropy due to the P–I stretching vibration.

© 2018 Elsevier B.V. CH3NH3PbI3-xClx-based perovskite photovoltaic devices were fabricated and characterized. The effects of CuBr or CuBr2addition on the photovoltaic properties and microstructures of the perovskite phase were investigated. The conversion efficiencies of the perovskite solar cells added with copper bromides were improved compared with the standard CH3NH3PbI3-xClxdevices. The efficiency of the device with CuBr2added was higher than that with CuBr added.

© 2018, Springer Nature B.V. Addition reaction between C60 and ethylenediamine occurred at room temperature in an ambient condition. C60-ethylenediamine adduct particles were prepared by mixing toluene solutions of C60 and ethyelenediamine. Average diameter of the C60-ethylenediamine adduct particles was changed non-linearly according to the reaction time, which were observed using transmission electron microscopy. Early stage of the reaction, the diameter of the adduct particles was changed from about 250 to about 430 nm. Then, the size of the adduct particles was converged to about 300 nm. During this addition reaction, the crystalline sizes of adduct particles were constant about 2–3 nm, regardless of the sizes of the adduct particles, which were determined by X-ray diffraction measurement.

© 2018 The Authors Additive effects of transition metals (M = Cr2+, Co2+, Cu2+and Y3+) on the electronic structures and magnetic properties of formamidinium lead halide perovskite compounds (FAPbI3, where FA = NH2CHNH2+) were investigated by first-principle calculation using density functional theory. In the case of Cr2+, Cu2+and Y3+-incorporated FAPbI3perovskite crystals, the electron density distribution of d-p hybrid orbital on the transition metal and iodine halogen-atoms were delocalized at frontier orbital. The total and partial density of state appeared the 3d-p hybrid orbital near the frontier orbital with narrowing band gap, yielding the wide broad absorption in the near-infrared region. The electronic correlation worked in between the localized spin on 3d orbital of the metal, and the itinerant carriers on the 5p orbital of the iodine halogen ligand and the 6p orbital of the lead atom in the perovskite crystal. The vibration behavior of the Raman and Infrared spectra were associated with change of polarization and slight distortion near the coordination structure. The considerable splitting of chemical shift of127I-NMR and207Pb-NMR in the Co2+and Cu2+-incorporated FAPbI3crystals were caused by crystal field splitting as Jahn-Teller effect with nearest-neighbor nuclear quadrupole interaction based on the charge distribution.

© 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim This paper presents the effects of copper (Cu) addition on the photovoltaic properties of perovskite CH3NH3PbI3−xClxsolar cells. The effects were investigated by measuring the current density–voltage (J–V) characteristics and external quantum efficiency. In the present work, CuBr and CuBr2were used as additives. The photovoltaic properties of the CuBr-added CH3NH3PbI3−xClxdevices showed a clear improvement. Structural and optical properties of the CuBr- and CuBr2-added CH3NH3PbI3−xClxfilms were also investigated. Based on the present results, the changes in the photovoltaic properties were discussed.

KGaA, Weinheim Effects of polysilane-doped 2,2′,7,7′-tetrakis-(N,N-di-p-methoxyphenylamino)-9,9′-spirobifluorene (spiro-OMeTAD) hole transport layers on photovoltaic properties were investigated by measuring current density–voltage characteristics and incident photon-to-current conversion efficiency of CH3NH3PbI3-based photovoltaic devices. Three kinds of polysilanes were used as the dopants. Due to the polysilane doping, conversion efficiencies of the CH3NH3PbI3devices using the polysilane-doped hole transport layers were improved. Microstructures of the CH3NH3PbI3devices were also investigated. Based on the results of the microstructure analysis, impact of silicon in the polysilanes doped into spiro-OMeTAD layer on photovoltaic properties were discussed.

© 2016 Elsevier Ltd A compact 150 W photovoltaic inverter was developed using SiC devices, which integrated a maximum power point tracking charge controller and a direct current (DC) - alternating current (AC) converter into a single module. The DC-AC converter circuit was built with four SiC metal-oxidesemiconductor field-effect transistors, while the DC-DC converter circuit built with four SiC Schottky barrier diodes. An increase of the switching frequency led to the module of a reduced size (250 × 180 × 28 mm3), which is just one third volume of a commercial Si-based inverter available today. Besides being compact, the conversion efficiency of the DC-AC converter was approximately 3% higher than that of the commercial Si-based inverter. In addition, the MPPT controller showed a conversion efficiency exceeding 96%, which raised the total efficiency under practical operation conditions up to 86%.
