Disclosed is a composition in a paste state for a solar cell. The composition contains a mixed aluminum powdery material prepared by mixing a small particle size aluminum powdery material, which has a particle size distribution (D50) of 3µm or less based on a laser analysis method and a ratio D10 to D90 (D10/D90) of 0.2 or more, and a large particle diameter aluminum powdery material, which has a D50 of 2 to 6 times the D50 of the small particle diameter aluminum powdery material and a ratio D10/D90 of 0.2 or more.
