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.
Claims10
A titanium dioxide nano ink comprising a titanium dioxide nano particle capped with a surface stabilizer represented by Chemical Formula 2, a dispersant which is a copolymer represented by Chemical Formula 5 in an amount from 0.1 to 10 parts by weight and a solvent:
- wherein R2 is hydrogen, C1-C20 alkyl, C2-C20 alkenyl, C2-C20 alkynyl or C6-C30 aryl,
- wherein n and m independently represent an integer from 1 to 30.
