METHOD FOR FORMING MULTIPLE-LAYER ELECTRODE STRUCTURE ON SOLAR CELL, METALLIZATION CONTACT STRUCTURE, PATTERNING METHOD OF LAYER, AND METHOD FOR FORMING FUNCTIONAL STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a method for forming a multiple-layer electrode structure for silicon solar cells.

SOLUTION: The method 10 for forming the multiple-layer electrode structure includes steps of: forming a conductive contact layer 20 on a semiconductor substrate 14; forming a metal bearing ink onto a portion of the conductive contact layer 20, so that the exposed portions of the conductive contact layer 20 are made adjacent to the metal bearing ink; and patterning the conductive contact layer 20 by removing the exposed portions of the conductive contact layer 20 from the semiconductor substrate 14.
