PASTENZUSAMMENSETZUNG UND SOLARBATTERIEELEMENT DAMIT

摘要

Provided are a paste composition capable of inhibiting formation of blisters and globules of aluminum in a back surface electrode layer, which is caused at the time of firing, and of reducing deformation of a silicon semiconductor substrate; and a solar cell element comprising an electrode formed by using the composition. The paste composition is used for forming an electrode (8) on a silicon semiconductor substrate (1) and comprises: aluminum powder; an organic vehicle; and a hydroxide. The solar cell element comprises the electrode (8) formed by applying on the silicon semiconductor substrate (1) the paste composition having the above-mentioned features and thereafter, firing the paste composition.
