<P>PROBLEM TO BE SOLVED: To provide a method for formation of a solar battery electrode which allows the formation of an electrode excellent in the adhesion with a base material, and a solar battery with an electrode produced by the method. <P>SOLUTION: The method for formation of a solar battery electrode comprises: a step which includes growing a film by coating a base material with a composition for electrode formation by a wet process; and a step which includes sintering the base material with the film grown on its upper face. In the method, a primer treatment is performed by applying an Ag metal oxide-containing coating material to the base material. The composition for electrode formation comprises a dispersant, and metal nano particles dispersed in the dispersant. The metal nano particles include not less than 75 wt% of silver nano particles. The metal nano particles are chemically modified with a protective agent whose carbon skelton comprises an organic molecule principal chain having 1-3 carbons. It is preferable that the metal nano particles contain metal nano particles having a primary particle diameter in a range of 10-50 nm, in a proportion of not less than 70% by number on the average. <P>COPYRIGHT: (C)2013,JPO&INPIT |
