摘要：
The SnO2-reduced graphene oxide (RGO) nanocomposites were firstly synthesized by one-pot route and then prepared for the films on FTO (SnO2:F) conductive glass as photoanodes in dye-sensitized solar cells (DSSCs) by a sol-gel method. The DSSCs were assembled with N3-dipped SnO2/RGO photoanode, Pt plate as counter electrodes and I-/I3- as an electrolyte. The SnO2/RGO nanocomposite photoanode was characterized. The photoelectric properties of DSSC were analyzed by volt-ampere (J-U) characteristic curve. The results show that SnO2/RGO nanocomposites as a photoanode in DSSC exhibit better photoelectric properties. The short-circuit current density (Jsc) and the open-circuit voltage (Uoc) of SnO2/RGO-DSSC are 15.56 mA/cm2 and 0.56 V, respectively and the photoelectric conversion efficiency is 4.58% when the mass ratio of GO and SnCl2 2H2O is 0.20. In addition, the effect of SnO2/RGO nanocomposites on the electron transport in the photoanode and PCE of DSSCs were also discussed. © 2017, Editorial Department of Journal of the Chinese Ceramic Society.
