CONDUCTIVE PASTE FOR FORMATION OF SOLAR CELL ELEMENT ELECTRODE, SOLAR CELL ELEMENT, AND METHOD FOR MANUFACTURING THE SOLAR CELL ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a conductive paste for forming a solar cell element electrode with excellent conversion efficiency capable while preventing the warp of a semiconductor substrate without causing an increases in cost.

SOLUTION: This conductive paste contains aluminum powder, an organic binder, a solvent and glass frit. The aluminum powder includes small particle size powder A of not more than 5.0μm in particle diameter and large particle size powder B of not less than 7.0μm in particle diameter.
