摘要： Disclosed is a method for producing a copper indium selenium (CIS) or copper indium gallium selenium (CIGS) thin-film light-absorbing layer. The method includes forming a coating layer of CIGS slurry, removing a solvent, a dispersant and a binder from the coating layer to form a powder coat layer, pressing the powder coat layer to improve its particle packing density, and heating the powder layer to form a dense thin film. The method uses a powder process as a non-vacuum process to produce a CIS or CIGS thin film in high yield at low cost. Further disclosed is a method for manufacturing a thin-film solar cell including the production method.
