| Research Abstract |
Dye-sensitized solar cells (DSCs) called Gratzel cells have attracted a great deal of interest, as they offer simple assembling process and low-cost fabrication alternative to silicon solar cells. In this study, for the purpose of the development of the new organic solar cell with the photovoltaic conversion efficiency (η) of 12%, the photochemical performance of the DSC comprised of the TiO_2 electrode prepared by (low-temperature plasma/ion-implantation) combined treatment has been investigated. The cells comprised of the Ar plasma irradiated and N or Zr ions-implanted TiO_2 electrode showed a higher short-circuit photocurrent density (Jsc) and higher η, compared with the original cell. It has been found that the (cold plasma/ion-implantation) continuous treatment is very effective technique to improve the performance of the DSCs with long wavelength absorption dye used as the oxide semiconductor sensitizer which was absorbed the solar light up to a wavelength of 920nm, and could be taken out energy effectively from the solar light.
