Provided are: a paste composition which is capable of keeping a desired function for a backside electrode of a solar cell and strengthening the bond between an aluminum electrode layer and a p type silicon semiconductor substrate even if glass frit as a substance giving a bad effect on the environment is not incorporated into the composition or the content of glass frit as a substance giving a bad effect on the environment therein is decreased; and a solar cell element provided with an electrode formed by use of the composition. The paste composition is a paste composition for forming an aluminum electrode layer ( 8 ) over a p type silicon semiconductor substrate ( 1 ), comprising aluminum powder, an organic vehicle, and a metal alkoxide. The solar cell element provided with the aluminum electrode layer ( 8 ) formed by applying the paste composition having the above-mentioned characteristic to the p type silicon semiconductor substrate ( 1 ) and then firing the resultant. |
