- the IZ0 may be made of various composition ratios, but in a preferred embodiment of the present invention has a composition ratio of In 2 0 3 90wt% and ZnO 10 ⁇ %.
- a plurality of masks having a predetermined interval are formed on the transparent substrate so as to prevent the transparent substrate from being completely exposed.
- the mask is formed so that a total of 11 transparent substrates are exposed.
- Ti-In ⁇ Zn-0 thin films having different compositions of IZ0 are formed.
- the Ti content increases from 1 to ®, and conversely, 11 Ti-In-Zn-0 thin films having a reduced composition ratio are formed.
- composition ratios of the 11 Ti-In-Zn-0 thin films according to the exemplary embodiment of the present invention are shown in Table 1 below.
- composition ratio of the element of the present technology Ti ⁇ In—Zn ⁇ 0 thin film is Ti content 4 ⁇ 34at%, Zn content, 9 ⁇ 17at%, In content 56 ⁇ 79% is preferred, as the Ti content increases, Zn content does not change much, but the relatively expensive In content tends to decrease significantly It is possible to manufacture economical transparent electrode for dye-sensitized solar cell.
- step (S200) to form a thin film according to an embodiment of the present invention can be carried out under various process conditions, in a preferred embodiment of the present invention was carried out at room temperature or low temperature without increasing the temperature.
- the minimum sheet resistance was shown at composition ratios of Ti 8at%, In 76at%, and Zn 16% (see FIG. 5).
- Dts in Table 2 means a distance between the transparent substrate and the first and second targets.
- the transparent substrate is a heat treatment process or a substrate for lowering the moisture content described in an embodiment of the present invention.
- the process may further include one or more of UV ozone or plasma pretreatment to improve adhesion to the dye layer.
- the Ti-In-Zn-0 thin film according to the present invention shows thin film characteristics having an amorphous structure over all samples regardless of the composition ratio.
- FIG. 10B illustrates a total 150 nm thick Ti-In—Zn Z 0 / according to an exemplary embodiment of the present invention.
- a real electron microscope image of a metal thin film (Ag) / Ti-In-Zn-0 three-layer transparent electrode is shown.
