Preparation And Photoelectric Properties Of CuCr2O4 Nanopowders

Abstract:

Article Preview

CuCr2O4 nanopowders were successfully prepared by co-precipitation technique from alcohol-aqueous system and applied for photo-anodes of dye-sensitized solar cells (DSSCs). The synthesized CuCr2O4 particles were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), UV–vis diffuse reflectance spectrum (UV-vis) and thermo-gravimetric/differential Scanning Calorimetry (TG-DSC). It was shown that, with the sintering temperature of 1000 °C and the amount of PEG-400 of 1.5 wt % , the size of primary crystal grain was about 48 nm. The CuCr2O4/TiO2 composite exhibit high absorption ability in the spectral range 600 ~ 900 nm, which leading to a much higher conversion efficiency (η) of the solar cell in comparison with the pure TiO2 film electrode.
