ALUMINIUM PASTE COMPOSITION AND SOLAR CELL DEVICE USING THE SAME

摘要

The present invention relates to an aluminum paste composition and a solar cell device using the same, and more specifically, to an aluminum paste composition which can improve Isc, Voc, and efficiency of a solar cell, and can minimize bending of the solar cell and formation of aluminum bubble or bump to an aluminum rear electrode layer by comprising: aluminum power in which the average grain diameter (D_50) is 1 to 5 μm; aluminum-nickel alloy powder in which the average grain diameter (D_50) is 0.1-10 μm; smokeless glass frit; and organic vehicle, and to a solar cell device using the same.
