Abstract: PURPOSE: A method for manufacturing a thin light absorption layer and a method for manufacturing a thin film solar cell using the same are provided to improve the density of a thin film in a low temperature sintering process by performing a powder process. CONSTITUTION: Coating solution is spread on a substrate to form a coating layer(S1). The coating solution includes copper indium selenium(CIS) or copper indium gallium selenium(CIGS) powder. A thermal process is performed on the coating layer under an inactive or a reductive gas atmosphere(S2). The powder layer is pressurized to improve the density of powder particles(S3). A thermal process is performed on the powder layer to form a thin film(S4). [Reference numerals] (S1) Forming a CIGS coating layer; (S2) Forming a powder layer according to volatilization of solvent; (S3) Pressurizing the powder layer; (S4) Forming a thin film by a thermal process
