METHOD FOR MANUFACTURING A SOLAR CELL

摘要

Provided is a method for manufacturing a solar cell. A light absorption layer is formed on a substrate. A buffer layer is formed on the light absorption layer. A window electrode layer is formed on the buffer layer. Forming the buffer layer includes depositing a metallic material on the light absorption layer, supplying a non-metallic material on the light absorption layer, supplying a gas material which includes oxygen atom on the light absorption layer, and making the non-metallic material react with the metallic material. The gas material including oxygen atom reacts with the metallic material and the non-metallic material to form metal sulfur oxide on the light absorption layer.
