    摘要: Disclosed herein are a glass frit and a composition for solar cell electrodes including the same. The glass frit includes lead oxide (PbO) and boron oxide (B2O3) in a weight ratio of lead oxide to boron oxide of about 1:0.075 to about 1:1, wherein a mixture of the glass frit and aluminum (Al) powder in a weight ratio of about 1:1 exhibits a phase transition peak in the range of about 400° C. to about 650° C. on a cooling curve obtained via TG-DTA analysis, measured after heating the mixture to 900° C. at a heating rate of 20° C./min, holding for ten minutes, followed by cooling the mixture at a cooling rate of 10° C. The composition can provide stable efficiency given varying surface resistance and minimize adverse influence on a p-n junction.
