Abstract
Provided are a paste composition capable of avoiding deteriorations in a mechanical strength and an adhesion property of an electrode layer, of sufficiently attaining a desired BSF effect, and of suppressing deformation (bow) of the silicon semiconductor substrate even in a case where a silicon semiconductor substrate is rendered thin; and a solar cell element including an impurity layer, or an impurity layer and an electrode layer, which is (or are) formed by using the above-mentioned composition. The paste composition is used for forming a p+ layer (7) or an aluminum electrode layer (5) on a silicon semiconductor substrate (1) and includes an aluminum-coated compound powder. Aluminum-coated compound particles constitute this aluminum-coated compound powder, and each of the aluminum-coated compound particles includes: a compound-particle of at least of one kind of a compound selected from the group consisting of an inorganic compound and an organic compound; and an aluminum-containing coating layer which covers a surface of the compound-particle, is located in an outermost surface of each of the aluminum-coated compound particles, and contains aluminum.
