Abstract: Disclosed are a titanium dioxide nano ink having such a strong dispersibility as to be applicable by inkjet printing and having adequate viscosity without requiring printing several times, and a titanium dioxide nano particle modified by a surface stabilizer included therein. Inkjet printing of the titanium dioxide nano ink enables printing of a minute electrode. In addition, efficiency of a solar cell may be maximized since occurrence of pattern cracking is minimized.
