PURPOSE: A method for bonding a solar cell is provided to easily control a co-firing condition by increasing a PN junction area and the depth of an N layer. CONSTITUTION: An N layer(22) is formed with a diffusion process using a P layer(20) as raw materials. An enlargement unit(28) is formed on the N layer using laser. An anti-reflection layer(24) is formed on the N layer. A metal electrode(26) is formed on the anti-reflection layer with a screen printing method. The metal electrode is inputted to the enlargement unit of the N layer via the anti-reflection layer. |
