Abstract
A solvent-free conductive paste composition including (a) a binder, (b) an initiator, (c) a glass powder and (d) a conductive powder; and a solar cell element having an electrode or wire made by coating and sintering the conductive paste composition coated on a silicon semiconductor substrate. The conductive paste composition is solvent-free so that it will not cause environmental problems with respect to the evaporation of solvents and will not be easy to spread out. The conductive paste composition facilitates the development of fine wire and high aspect ratio designs and can efficiently enhance the photoelectric conversion efficiency.
