<p>PURPOSE: A method for manufacturing a cigs solar cell is provided to uniformly diffuse an alkaline element into a light absorption layer without a separate process. CONSTITUTION: A back electrode(200) is formed on a substrate(100). A precursor is formed on the back electrode. The precursor is heat-treated to form a light absorption layer(300). Alkali gas is additionally supplied to a thermal process space in the precursor. A buffer layer(400) is formed on the light absorption layer. A front electrode(500) is formed on the buffer layer.</p> |
