摘要
The aligned hexagonal cadmium sulfide nanorods (CdSNR) have been synthe-sized by hydrothermal technique at 200ºC on fluorine tin oxide (FTO) sub-strates. Dye sensitized solar cells (DSSCs) based on the photoelectrode core-shell CdSNR array with conductive polymers nanocomposite of polyaniline (PANI) and poly(3,4-ethylenedioxyl-thiophene)/poly(styrene-sulfonate) (PEDOT:PSS) were fabricated and designed with different types of dye molecules. DSSCs were characterized utilizing scanning electron microscopy (SEM), Raman scattering, energy dispersive spectroscopy (EDS), UV-Vis absorption spectroscopy, X-ray diffraction (XRD), and photocurrent-voltage (J-V) characteristic. Results show that under illumination (AM 1.5 G), the high power conversion energy (PCE) was achieved for CdSNR/PANI-PEDOT:PSS device when it sensitized with ruthenium (II) (dye N-719) of 0.91% and a short circuit current density (Jsc) of 4.21 mA/cm2 in comparison with the other devices, which sensitized with natural dyes. The high performance of the CdSNR/PANI-PEDOT:PSS-N719 device attributed to the wide range of absorption and photostability for N719. This work shows that the CdSNR with N719 can be appropriate candidate for photovoltaics device for their low cost fabrication procedure and excellent absorption.
