METHOD FOR MANUFACTURING LIGHT-ABSORPTION LAYER FOR SOLAR CELL, METHOD FOR MANUFACTURING THIN FILM SOLAR CELL USING THE SAME AND THIN FILM SOLAR CELL USING THE SAME

摘要

PURPOSE: A method for manufacturing a light absorption layer, a method for manufacturing a thin-film solar cell using the same, and the thin-film solar cell are provided to produce an environment-friendly product by omitting a selenization process. CONSTITUTION: An alloy particle and a chalcogen element are included in a metal particle. The metal particle is coated on a substrate. The metal particle coated on substrate is light-sintered. The alloy particle is composed of a CuIn1-xGax element. A Se element is included in the metal particle which includes the chalcogen element.
