METHOD FOR FORMING SOLAR CELL COLLECTING ELECTRODE, SET OF CONDUCTIVE COMPOSITIONS FOR FORMING SOLAR CELL COLLECTING ELECTRODE, AND SOLAR CELL

摘要

The purpose of the present invention is to provide a method for forming a solar cell collecting electrode whereby an electrode having excellent solder cohesion can be formed. This method for forming a solar cell collecting electrode is a method for forming a solar cell collecting electrode in which a conductive composition for forming a solar cell collecting electrode, including at least conductive particles (A), glass frit (B), and a solvent (C), is used to form a solar cell collecting electrode, wherein the method for forming a solar cell collecting electrode has a finger electrode formation step in which a conductive composition for forming a finger electrode containing a metal oxide (D) in a proportion of 3-10 mass parts to 100 mass parts of the conductive particles (A) is used to form a finger electrode; and a bus bar electrode formation step subsequent to the finger electrode formation step, in which a conductive composition for forming a bus bar electrode containing a metal oxide (D) in a proportion of less than 3 mass parts to 100 mass parts of the conductive particles (A) is used to form a bus bar electrode.
