COMPOSITION FOR FORMING SOLAR CELL AND ELECTRODE PREPARED USING THE SAME

摘要

The present invention relates to a composition for forming an electrode of a solar cell comprising conductive powder, glass frit, organic vehicle, and thixotropic agent, and having 1.5-4 of a first thixotropic index (TI I) measured by a rotational viscometer at 23°C and displayed as Formula 1, and 4-8 of a second thixotropic index (TI II) displayed as Formula 2. The composition makes a printed pattern with a micro line width and a high aspect ratio, and the thickness uniformity of the printed pattern is excellent. [Formula 1] TI I = Viscosity at 1 rpm / Viscosity at 10 rpm, [Formula 2] TI II = Viscosity at 10 rpm / Viscosity at 100 rpm.
