摘要:
Pt nanoparticles (about 1.8 nm in diameter) protected with a polymer layer are prepared by a chemical reduction of Pt ions in the presence of PVP [poly(N-vinyl-2-pyrrolidone)]. PVP-capped Pt nanoparticles can be well dispersed in an isopropyl alcohol solution due to the electrostatic repulsion between Pt nanoparticles and steric repulsion between the adsorbed PVP layers. An ultrathin layer of PVP-capped Pt nanoparticles is homogeneously deposited onto the fluorine-doped tin oxide (FTO) glass by electrophoretic deposition (EPD). The photoelectron conversion efficiency of the dyesensitized solar cell is increased from 0.02 to 6.00% after employing the cathode with ultrathin transparent Pt layer prepared by EPD.
