The effect of the introduction of a CF3 group to a silyl-anchor moiety of the sensitizer on the sensitizing property for the dye-sensitized solar cell was examined by using alkoxysilyl-anchor azobenzene dyes. The cell sensitized by the silyl-anchor dye with the electron-withdrawing CF3 group in the silyl-anchor moiety exhibited higher photovoltaic performance than that by the silyl-anchor dye without the CF3 group.

A magnetic polymer electrolyte using agarose as polymer matrix, NMP as solvent and NiO nanoparticles as modifier was investigated and employed in the dye-sensitized solar cell (DSSC) in this paper. The influence of NiO nanoparticles content on magnetic polymer electrolyte was characterized by SEM and ionic conductivity test. The photovoltaic properties of the corresponding DSSCs were studied by photovoltaic performance tests. The results showed that the surface morphology of the polymer electrolyte with 1.0wt% NiO nanoparticles was smooth and this magnetic polymer electrolyte showed the maximum conductivity (2.43×10-3S•cm-1). The optimal photoelectric efficiency of 1.63% was achieved at the NiO nanoparticles content of 1.0wt%.

In this work, several liquid electrolytes (LE) have been prepared. The electrolytes contain tetrapropylammonium iodide (TPAI) salt with different salt content, propylene carbonate (PC), ethylene carbonate (EC), polyethylene oxide (PEO), dimethylformamide (DMF) and (I-/I3-) redox couple LE was used in the Dye-Sensitized Solar Cell (DSSC). DSSCs were fabricated and current density-voltage (J-V) characteristics measured. The highest incident photon conversion efficiency (IPCE) at 520 nm is 45.5% for DSSC with 0.25 g TPAI LE. At AM 1.5, DSSC with LE exhibits efficiency of 6.61% with Jsc= 18.69 mA cm-2, Voc= 0.68V and fill factor (FF) = 0.52.
