Summary A systematic study is done on the preparation of ZnO/CeO2 mixed metal oxide (MMO) as a photoanode for dye‐sensitized solar cells (DSSCs). The MMOs are simply prepared via calcination of the Zn/Ce‐layered double hydroxides (Zn/Ce‐LDHs). The urea decomposition method is utilized for the preparation of the LDHs. Herein, the effect of various synthesis conditions, namely the amount of urea, the molar ratio of Zn2+ to Ce3+, and the calcination temperature on the photovoltaic performance of DSSCs are carefully evaluated. This is the first attempt to investigate the effect of the urea amount used in the synthesis of the LDH on the photovoltaic performance of the corresponding MMO in DSSCs. For this purpose, three series of the DSSCs are assembled by the three series of the MMOs that are synthesized under different conditions. The electrochemical method is used for measuring the photovoltaic performance of the DSSCs. All the examined parameters have a significant influence on the efficiency of the DSSCs. The best conversion efficiency reaches 2.08% (Jsc = 6.34 mA cm2, Voc = 0.68 V, and FF = 0.48) by using 20:1 molar ratio of urea to metallic cations (Zn2++Ce3+) and 8:1 molar ratio of Zn2+ to Ce3+ and calcination of LDH at 700°C. This is the best efficiency reported for the MMO based DSSCs.

To reveal the intrinsic mechanism of MnxZn1‐xFe2O4 (x=0.2, 0.4, 0.6, 0.8 and 1) nanoferrite with various content of Mn/Zn are prepared by hydrothermal method. The physical properties are characterized by X‐ray diffraction (XRD), Fourier transformed infrared spectrometer (FTIR), Transmission electronic microscope (TEM), Energy Dispersion Spectrum (EDS) and Vibrating Sample Magnetometer (VSM). The phase structure, lattice parameters, and magnetic properties have been investigated based on the entire cation distribution with enhancement of the Mn2+. The XRD and FTIR analysis indicate that the samples have cubic spinel ferrite structure, the lattice constant at and crystallite size D increase with enhancement of Mn content. The VSM plots demonstrate that the Mn0.6Zn0.4Fe2O4 sample has the largest saturation magnetization value (77 emu/g). These results indicate that a fine tuning of Mn2+ content can adjust the micro‐structure and magnetic properties of MnxZn1‐xFe2O4.
