Preparation and Performance Characterization of “Turnjujube-Like” CdSe Nanofibers

Abstract:

It was reported for the first time that “Turnjujube-like” CdSe nanofibers have been assembled onto TiO₂ surface by electrochemical method of cyclic voltammetry, using CdSO₄•8H₂O and SeO₂ as raw material, can be used as a sensitizer of quantum dot-sensitized solar cell. CdSe morphology, structure characterization and optical properties are characterized by scanning electron microscope (SEM), X-ray diffraction (XRD), and ultraviolt-visible spectroscopy (UV–Vis), respectively. The experimental results show that the prepared “Turnjujube–like” CdSe nanofibers are zinc blende CdSe with cubic crystal system, and it have excellent light absorption within the wavelength range of 300–800 nm. It has a potential for the construction of QD-sensitized solar energy cell.
