BiFeO3 thin films were fabricated by a simple spin-coating method as an electron transport layer in CH3NH3PbI3-based photovoltaic devices. Single-phase BiFeO3 was obtained, which was confirmed by X-ray diffraction. To characterize photovoltaic properties, BiFeO3/CH3NH3PbI3-based photovoltaic devices were fabricated by different preparation steps for CH3NH3PbI3 layer, and current density-voltage characteristics of the photovoltaic devices showed rectifying behaviors. Comparing with the BiFeO3/CH3NH3PbI3 photovoltaic device fabricated by a 1-step method, the conversion efficiency of the device fabricated by a 2-step method was improved. Bandgaps of the BiFeO3 and CH3NH3PbI3 layers were also determined from optical absorption measurements. (C) 2016 The Ceramic Society of Japan. All rights reserved.

Effects of PbCl2 addition to perovskite CH3NH3PbI3 precursor solutions on the photovoltaic properties were investigated. TiO2/CH3NH3PbI3-xClx-based photovoltaic devices were fabricated, and the microstructures of the devices were investigated by X- ray diffraction. The structure analysis indicated phase transformation of the perovskite structure from cubic to tetragonal system by chlorine (Cl)-doping. External and internal quantum efficiencies were improved by a small amount of Cl- doping, which resulted in improvement of the efficiencies of the devices. This would be due to preservation of the cubic CH3NH3PbI3-xClx structure, and to expansion of energy gap and diffusion length of exitons by Cl-doping at the iodine sites.

Effects of SbI3 addition to CH3NH3PbI3 precursor solutions on the photovoltaic properties were investigated. TiO2/CH3NH3Pb1-xSbxI3-based photovoltaic devices were fabricated in air, and formation of a perovskite-type structure was confirmed by X-ray diffraction. The conversion efficiencies were improved by adding a small amount of Sb, and formation of PbI2 was suppressed by the Sb addition.

Perovskite-type CH3NH3PbI3-based photovoltaic devices were fabricated and characterized. Doping effects of thallium (Tl), indium (In), or germanium (Ge) element on the photovoltaic properties and surface structures of the perovskite phase were investigated. The open circuit voltage increased by Ge addition, and fill factors were improved by adding a small amount of Ge, Tl or In. In addition, the wavelength range of incident photon conversion efficiencies was expanded by the Tl addition.

TiO2/CH3NH3PbI3-based photovoltaic devices were fabricated by a spin-coating method using a mixture solution. TiO2 require high-temperature processing to achieve suitably high carrier mobility. TiO2 electron transport layers and TiO2 scaffold layers for the perovskite were fabricated from TiO2 nanoparticles with different grain sizes. The photovoltaic properties and microstructures of solar cells were characterized. Nanoparticle sizes of these TiO2 were 23 nm and 3 nm and the performance of solar cells was improved by combination of two TiO2 nanoparticles
