TWICE PRINTED SOLLAR CELL, APPARATUS AND METHOD FOR MANUFACTURING THE SOLLAR CELL

摘要

PURPOSE: A solar cell manufactured by a twice printing method, an apparatus for manufacturing the same, and a method for manufacturing the same are provided to increase an area on which solar light is received by narrowing the width of a finger electrode. CONSTITUTION: A first screen mask is installed on a silicon wafer(120). Silver paste is applied to the first screen mask. According to the pattern of the first screen mask, a finger electrode(126) and a bus bar electrode are printed on the silicon wafer. An additional printing process is performed with respect to the finger electrode. The finger electrode includes a first finger electrode and a second finger electrode. The width of the second finger electrode is narrower than that of the first finger electrode.
