Provided are a paste composition capable of not only meeting appearance characteristics in that no bow of a silicon semiconductor substrate is caused and no blisters and globules of aluminum in the aluminum electrode layer obtained after firing are caused, but also meeting characteristics in that adhesiveness of an aluminum electrode layer and the silicon semiconductor substrate is enhanced and in that reaction of the aluminum electrode layer and moisture is suppressed; and a solar cell element including electrodes formed by using the composition. The paste composition is a paste used for forming an electrode (8) on a silicon semiconductor substrate (1), comprising: an aluminum powder, an organic vehicle, and glass frit, the glass frit including at least one kind of a transition metal oxide selected from the group consisting of a titanium oxide, a vanadium oxide, an iron oxide, a molybdenum oxide, a neodymium oxide, and a tungsten oxide. A solar cell element includes a back side electrode formed by using the above paste composition. |
