Provided is a carbon nanotube water dispersion with which it is possible to form a conductive film that has excellent film strength and can cause a solar cell to display excellent conversion efficiency and reliability. The carbon nanotube water dispersion is for an electrode of a solar cell that includes an electrolyte solution containing a polar aprotic substance as a solvent and contains carbon nanotubes, a dispersant, a thickener, and water. The dispersant is soluble in the solvent and the thickener is insoluble in the solvent.

A pyrography composition includes ammonium chloride in an amount of about 2% to about 15% by weight; a thickener in an amount of about 10% to about 40% by weight; and water in an amount of about 50% to about 75% by weight of the total composition. The composition is a gel paste which, due to its high viscosity, remains stationary throughout the application process, maintaining edge retention for highly detailed design.
