t has been attempted to utilize plastic substrates for electrodes, instead of conventional glass substrates, to fabricate flexible, lightweight, and low-cost dye-sensitized solar cells (DSSCs). We examined a pyrolysis method by which preformed layered hydroxide zinc acetate (LHZA: Zn5(OH)8(CH3COO)2·2H2O) films were converted into ZnO films at temperatures below 120 oC. Since the pyrolyzed films still contained zinc acetate compounds, they were immersed in hot water aiming at removing such the impurities. This hot water treatment influenced the film morphology to a large extent. The energy conversion efficiency of 3.41% was obtained for the cell using an N719/ZnO electrode fabricated on an indium tin oxide-coated polyethylene naphthalate (ITO-PEN) substrate through the present pyrolysis method.

Dissolution And Precipitation

For fabrication of plastic dye-sensitized solar cells, we propose a dissolution and precipitation method to form nanostructured ZnO films on plastic substrates. Layered hydroxide zinc acetate (LHZA) films on plastic substrates were immersed in acetonitrile at 60 oC. They were converted into ZnO films through the dissolution of LHZA and the precipitation of ZnO in acetonitrile. The resultant films contained a large amount of zinc acetate compound impurities, which were attempted to be removed from the ZnO films by dissolving in water. We achieved the energy conversion efficiency of 2.3% for the N719/ZnO electrode on an ITO-PEN substrate.

Dye sensitized solar cells (DSSCs) were fabricated using silver doped ZnO films deposited on ITO glass by spin coating method. The crystalline nature of ZnO films was analysed with XRD and SEM technique was used for morphological studies. The XRD pattern confirmed the presence of single phase hexagonal wurtzite ZnO structure, without the presence of secondary phase. The crystallite size of ZnO decreased from 31 nm to 25 nm with increase in doping to 1.5mol% of silver. The UV-visible transmission of the prepared ZnO film was found to be 70-90% and it decreased with increase in doping to 0.5mol% Ag and increased in the film doped with 1.5mol% Ag. The band gap values of the ZnO films with 0, 0.5 and 1.5mol% of silver, determined from Tauc plot, were 3.269, 3.235 and 3.257 eV, respectively. The absorbance peaks of the N719 dye loaded ZnO films were obtained at the wavelengths 310, 350 and 538 nm. The N719 dye loaded ZnO film doped with 0.5mol% Ag has the highest absorbance in the visible region as compared to other two samples. The fill factor values of the pure and ZnO doped with 0.5 and 1.5mol% Ag were 0.47, 0.48 and 0.42, respectively. The short circuit density values for ZnO, ZnO:Ag0.5% and ZnO:Ag1.5% were found to be 1.50, 1.55 and 1.15 A?m/cm2, respectively. The calculated photon to electron efficiencies for the ZnO films with 0, 0.5 and 1.5mol% of silver were 0.42%, 0.44% and 0.27%, respectively. Consequently future prospective of such type of dopants in ZnO film based dye sensitized solar cells seems to be bright.
