Method of forming an electrode structure and method of manufacturing a photovoltaic cell using the same

A method of manufacturing a photovoltaic cell, comprising:

• depositing an amorphous silicon semiconductor layer on a crystalline silicon layer to form a p-n junction;
• forming a transparent conductive layer on the amorphous silicon semiconductor layer;
• forming a preliminary metal pattern on the transparent conductive layer by performing an ink jet process using glass frit-free nano metal ink;
• forming a metal paste layer using a conductive paste through a screen printing process to cover the preliminary metal pattern;
• and
• firing the preliminary metal pattern and the metal paste layer to transform the preliminary metal pattern and the metal paste layer into a first metal pattern and a second metal pattern such that the first and the second metal patterns are formed on the transparent metal layer to define a metal electrode.
