초록

Dye-sensitized solar cell (DSC) is a promising alternative solar cell to the conventional silicon solar cell due to several advantages. Development of large scale module is necessary to commercialize the DSC in the near future. A scribing technology of the transparent conductive oxide (TCO) is one of the important technologies on the fabrication of DSC module. A quality of the scribed line on the TCO has a decisive effect on the efficiency of DSC module. Among several scribing technologies, the fiber laser is a suitable for scribing the TCO more precisely and accurately because of their own characteristics. In this study, we try to improve the quality of the TCO scribed line by using the fiber laser. Consequently, the operating parameter of fiber laser is optimized to get the TCO scribed line with good quality. And the fiber laser scribing technology of the TCO is applied to the fabrication of the DSC with optimal operating parameter, operating current 3900mA. As a result, the current density and fill factor are improved and the total efficiency is increased because the internal resistances of DSC such as TCO sheet resistance and the resistance concerned to the electron movement in the $TiO_2$ are reduced. This is analyzed by the electrochemistry impedance spectroscopy (EIS) and the equivalent circuit model of the DSC.
